If floodwater threatens your home, workplace, school or travel route in Poland, follow the latest IMGW hydrological warnings and instructions from your local authorities, and leave an exposed area promptly when evacuation is ordered. Do not drive, cycle or walk through moving floodwater. The road may be undermined, and muddy water can hide deep holes, damaged culverts, electrical equipment or dangerous current. A dry-looking bank or bridge approach may also collapse after sustained water erosion.
If you receive an Alert RCB SMS, read the actual location and recommended action; the service is designed to warn people in areas of serious danger. You do not need to register or install an app to receive it. For an immediate emergency involving trapped or injured people, call 112 and provide the exact address, town, nearby river or bridge, number of people and access problems. Fire, ambulance and police have familiar specialist numbers, but 112 is the nationwide general emergency contact.
This practical guide is for families, students, workers, farmers, drivers and visitors across Dolnośląskie, Opolskie, Śląskie, Małopolskie, Mazowieckie, Podkarpackie, Wielkopolskie, Pomorskie and other regions. It explains river flooding along the Wisła (Vistula), Odra (Oder), Nysa Kłodzka, Warta, Narew and other catchments, flash floods after heavy rain, RCB messages, evacuations, water safety and recovery. For current information use the Polish Government Centre for Security’s flood guide, IMGW hydrological monitoring, Poland’s official safety handbook and local municipal or voivodeship authorities. This is general safety education, not a live Polish river-height or road-status report.
Quick answer: twelve actions during a flood
- 1. Check current IMGW forecasts and hydrological alerts for the exact river and area, and read local emergency instructions.
- 2. If authorities announce evacuation, leave promptly on the designated safe route; do not delay to rescue furniture or a vehicle.
- 3. Never cross moving floodwater on foot, bicycle or in a car, even if a large truck has recently passed.
- 4. Keep children, older people and residents with disabilities away from low flood paths, and arrange safe transport early.
- 5. Avoid flooded basements, garages and electrical rooms; do not enter water to operate breakers or recover possessions.
- 6. Before water arrives, and only when safe, prepare essential medicines, identification, food, drinking water, warm clothing and communication.
- 7. Read Alert RCB messages sent to phones in relevant threatened areas; no subscription or app installation is needed.
- 8. For urgent rescue or medical danger, dial 112 and give your location, number of people and whether the entry road is blocked.
- 9. If you cannot evacuate, seek a suitably protected higher location with rescue access, and follow official guidance.
- 10. Know official rescue signals: a white flag for evacuation need, red for urgent medical help, and blue for food or water needs, where rescuers can see them.
- 11. Treat flood-affected water, food, electricity and gas systems as potentially unsafe until properly assessed.
- 12. Return only after responsible authorities permit access and important structural, sanitation and utility hazards have been addressed.
These directions come from the Polish government’s current flood safety handbook, RCB flood guidance and Ministry of Interior’s official instructions.
First understand powódź and podtopienie
Powódź is the Polish term for flooding, often used when water spreads into normally dry land and threatens homes or infrastructure. Podtopienie commonly refers to local inundation or waterlogging, which may affect a street, basement or property without becoming a large river disaster.
Both can be dangerous. Rapid urban flooding can fill an underground garage, while prolonged river flooding can damage large neighbourhoods and rural farms.
A person outside a historic floodplain may still experience a dangerous stormwater problem. Conversely, a family beside a large river may have several days of monitoring before water arrives.
The correct protective action depends on where the water can reach you and how quickly your safe route may close.
Poland’s major rivers and catchments
Poland’s rivers include the Wisła (Vistula), Odra (Oder), Warta, Narew, Bug, Bóbr, Nysa Kłodzka and Dunajec, among others.
River floods can develop after heavy rain across a catchment and travel downstream. A town that has stopped receiving rain may still face rising water coming from tributaries or higher parts of the river system.
Local geography, flood defences and drainage affect which streets become exposed. A high reading at an upstream station is useful background, not a direct measurement of water depth inside an individual building.
Monitor the actual river and local instructions rather than relying on the weather outside your window alone.
IMGW: who provides Poland’s weather and water information?
The Instytut Meteorologii i Gospodarki Wodnej – Państwowy Instytut Badawczy (IMGW-PIB) provides meteorological and hydrological monitoring, forecasts and warnings.
Its hydrological portal includes observed river conditions and relevant warnings. The hydrological warning view helps readers locate current advisories.
The Polish Water Authority’s government page explicitly directs residents to IMGW for up-to-date hydrological and meteorological warnings.
Use the current observations and forecast to prepare, but rely on local authorities for specific evacuation, shelter and road directions.
What a river-level graph tells you—and what it does not
A river gauge shows water level at one station relative to a particular reference. It may indicate a rising trend or alert threshold.
But it does not tell the exact water depth beside your home, the condition of a nearby bridge or whether your municipality has completed an evacuation.
Different stations have different reference levels. Comparing raw heights across rivers without context can be misleading.
Check the station name, observation time, forecast, trend and warning interpretation, then follow current instructions for your neighbourhood.
Weather warnings versus hydrological warnings
A meteorological warning can tell you that heavy rain or thunderstorms are expected. A hydrological warning concerns river and water-system conditions such as dangerous rises.
These products complement each other. Heavy rain in a city may cause sudden street flooding before a major river level changes significantly.
A river may continue rising after local weather becomes calmer. One warning ending is not necessarily the end of the other hazard.
Read both weather and water information when either could affect your road or property.
IMGW and the three warning levels
IMGW warning products can use numbered severity levels, commonly 1, 2 and 3, with higher levels indicating greater potential concern for the specific hazard.
Do not treat the number as a prediction that every building in the affected county will flood. The expected effects and place named in the message are essential.
A local road already covered by strong current must not be crossed even if an older general warning was only level 1 or 2.
Public warning levels support decisions but do not replace actual conditions or official closures.
Wody Polskie and flood hazard information
Wody Polskie supports water management and related public information. Flood hazard and risk mapping also help identify areas that may be exposed under certain scenarios.
The Polish flood safety handbook references Wody Polskie, flood information maps and IMGW as useful sources for preparedness.
A hazard map supports planning over years, but is not a live street-level depth map. Roads, buildings and the actual event may create conditions different from a broad modelled boundary.
Use hazard maps to prepare a family plan, and current alerts to decide what to do today.
What is Alert RCB?
Alert RCB is Poland’s government emergency SMS warning system, managed by the Rządowe Centrum Bezpieczeństwa (Government Centre for Security).
It is used in extraordinary situations when serious threats may affect the health or lives of people within a specified area.
RCB gathers information from weather institutions, public services and regional authorities. The SMS message describes the danger and gives practical instructions.
The official English RCB guidance explains that the system is not a general weather newsletter and is not sent for every minor event.
Alert RCB requires no registration or app
The Polish government specifically states that no sign-up, subscription or app installation is necessary to receive Alert RCB.
Mobile operators send messages to phones within the affected area according to the alert distribution rules. Prepaid subscribers are included.
A person who does not receive an SMS should not assume the river or road is safe; network conditions, targeting and the hazard itself may differ.
Recognising the physical danger and following local instructions remain essential even without an alert on your handset.
What to do when you receive an RCB SMS
Read the hazard, affected area, date and requested action. The message may instruct people to avoid travel, prepare for flooding or follow evacuation directions.
Do not forward an old screenshot as a new alert without confirming its time and location. A warning may apply to a particular powiat (county) rather than the entire country.
The RCB’s official warning examples describe the importance of clear actions and verified information.
A genuine SMS is useful because of the decision it directs, not because the text contains an alarming word.
Why RCB alerts are not sent for every local flood
The RCB service is intended for exceptional significant threats. A small local storm or street inundation may not meet its national alert criteria.
The official FAQ explains that not every highly local weather event can be predicted in advance.
If water is already flowing across the road, do not wait for a national SMS before turning back. Follow emergency service and local authority directions.
A warning system complements, rather than replaces, physical safety decisions.
The first step before a forecast river flood
If the area is at risk, identify the current local evacuation plan, likely road closures and an accessible safe destination.
Prepare essential medicines and documents, charge phones and gather water, food, clothing and a flashlight in an accessible place.
Where officials advise and it can be done safely ahead of the water, move vehicles and vulnerable goods to a suitable flood-free area.
The preparation period should be used for decisions that become impossible after roads and basements flood.
Sandbags and household protection
Sandbags and temporary barriers may help with some lower-level water intrusion when correctly planned, but they do not guarantee protection against deep or fast flooding.
Do not remain on an exposed property solely to defend furniture or equipment once authorities direct evacuation.
Water pressure can damage walls, doors or drains. Improvised barriers may fail or redirect water in ways the household did not anticipate.
Property protection is secondary to preserving a safe route for people to leave.
Basements and underground garages
A basement may fill through a stairwell, drain or garage ramp. Water can block doors and introduce electrical hazards.
Do not descend to recover a vehicle or stored property once water is entering. The main switchboard may be submerged even if the lighting is still on.
Before flooding, safe professional utility isolation may be part of the plan. But never enter floodwater to operate a breaker or gas valve.
An underground car park can become a trap much faster than a person expects.
The electrical and gas isolation decision
Polish government guidance recommends disconnecting electrical and gas supplies as part of appropriate flood preparation.
This instruction applies only when it can be done safely, from a dry accessible position and by someone authorised or suitably competent.
If equipment is already submerged, leave it alone and seek professional or emergency assistance. A power outage does not prove the system is harmless.
Do not create an electrocution or explosion hazard while attempting to protect a building.
Moving valuables to higher floors
When there is time before the flood arrives, documents, essential electronics and valuable property may be moved above expected water levels.
But never delay a mandatory evacuation to relocate large furniture, heavy appliances or stock.
A household should prioritise medicines, identification, communication, food and water over replaceable possessions.
The most effective protection is leaving people and essentials in a safe place before access is cut off.
Lower Silesia, Opole and southern catchments
Some southern and southwestern Polish regions contain rivers and valleys where intense rainfall can affect urban and rural communities.
A flood near a tributary or mountain catchment can develop differently from one affecting a broad major river valley. A road may become unsafe before the nearest main river gauge shows a dramatic level.
Check the relevant local authority and IMGW warning for the exact river and community.
Do not use a photograph from a previous flood as a substitute for current river and road information.
The Odra and Wisła are different river systems
The Odra and Wisła systems have distinct catchments, tributaries and regional risk patterns.
A warning on one river does not automatically describe every location along the other. Even within one river system, upstream and downstream towns may experience different timing.
A family should know which tributary or drainage channel affects its property and which bridge provides the safest exit.
The correct river and station must be identified before a forecast becomes useful to a household.
Urban floodwater in Warsaw, Kraków and other cities
City drainage can be overwhelmed by intense rain, collecting water in underpasses, lower streets and underground parking.
A major river may remain below its flood threshold while urban runoff still makes local roads dangerous.
Avoid a water-covered road even if a navigation app shows it as open. The hidden depth may be far greater in the centre than at the edge.
The safest urban response is often stopping before the flooded low point and choosing an officially safe alternative.
Flooding after heavy rain in mountain areas
Steeper catchments can concentrate runoff rapidly, while saturated slopes may release rocks or mud onto roads.
A family moving from water must avoid a newly unstable cliff or retaining wall. A mountain road covered by fresh debris should not be used to reach another village.
Respect closures and wait for responsible road or emergency services to assess the area.
The safe evacuation path must avoid both floodwater and ground movement.
Why driving through floodwater is dangerous
Moving water can push vehicles sideways, flood engines and conceal damaged road structures.
A road may appear shallow near the kerb but have a deep drop in the middle. A four-wheel-drive car is not protection against a washed-out bridge.
Turn around safely rather than accelerating through the water. Do not send passengers ahead to measure depth.
A replaceable vehicle is not worth the possibility of drowning or creating another rescue emergency.
Walking and cycling are not safer substitutes
Swift water can knock down a pedestrian or carry them into a drain or channel. A cyclist may lose balance and be unable to regain control.
Do not wade to reach a shop, school or bus stop. Avoid paths beside eroding riverbanks.
Follow a dry authorised route or shelter in a suitable protected place until travel is safe.
A person should not be used as a depth gauge for a dangerous crossing.
Road and bridge closures
During floods, police, firefighters and road authorities may restrict bridges, riverbank roads and tunnels.
Do not bypass barriers even when one lane looks clear. Hidden erosion, debris or structural concerns may remain.
A bridge visible above the water might still need inspection after high current. Another driver’s crossing does not prove its safety.
Only responsible authorities can confirm reopening of an assessed crossing.
When a local evacuation order is announced
Follow the specified area, route and destination. Leave while travel remains safe and bring essential medication, identification and household supplies already prepared.
Do not remain to protect property or livestock once departure is required. The Polish RCB guidance warns that remaining in inundated areas can expose people to drowning, disease and interruption of electricity, water and sanitation.
A designated school or public centre may not be operating during every flood, so verify current shelter instructions.
Early evacuation preserves the greatest range of safe transport options.
What if water already blocks the exit?
If the street and ground-level route are covered by dangerous current, do not try to wade to the original shelter.
Move to a suitable higher protected level with a means of rescue access and call 112, reporting floor, location, occupants and any medical needs.
Avoid an attic with no safe exit or a visibly unstable roof. Follow official instructions on signalling to rescuers.
A route that was once safe may now create greater danger than protected temporary refuge while professional help is arranged.
Poland’s white, red and blue flood-rescue flags
The Polish government’s current security handbook describes visible flag signals for people who cannot evacuate:
- White flag — I need evacuation.
- Red flag — I need medical assistance.
- Blue flag — I need food and drinking water.
A flag can be made from a clearly visible piece of clothing, according to the official guidance. These signals are useful when responders can see the building.
They do not replace calling 112 or following emergency instructions when communication is available. Do not expose yourself on an unstable roof merely to display a flag.
Why a flag does not guarantee immediate rescue
A visible flag communicates a need but does not tell responders every detail about the building, injured people or access hazards.
Where possible, call 112 and explain the exact situation, then use a safe visible signal as an additional aid.
Do not stand on a balcony or roof that appears structurally compromised to attract attention. Choose the safest practicable observation position.
The purpose is to make a trapped household visible without creating another danger.
Polish emergency numbers: 112 and specialist services
Poland uses 112 as its general emergency number. The Ministry of Interior’s flood page also lists:
- 998 — Straż Pożarna, the fire service.
- 999 — Pogotowie Ratunkowe, ambulance and urgent medical help.
- 997 — Policja, police-related emergencies.
For a flood incident involving trapped or injured people and uncertainty about which service is needed, 112 is the straightforward starting point.
Give exact location and access conditions. Emergency operators can coordinate appropriate responders.
What to tell a dispatcher in Poland
Report the voivodeship, town or village, address, nearby river or bridge and number of affected people.
Explain whether water is rising, how many floors are occupied, whether anyone is injured or unable to use stairs, and which approach roads are closed.
A concise statement such as “Three people on the second floor in this village, ground-level exit underwater, one person needs medical assistance” is actionable.
Keep a phone available for callbacks and follow the operator’s instructions.
Families with infants and older people
Flood evacuations can be difficult for infants, older residents and people with medical conditions. They may require more time, accessible transport or specialised healthcare arrangements.
Prepare medication, infant feeding materials, clean water and appropriate equipment ahead of the expected flood. A general shelter may not have every specialist facility, so ask local officials early.
Do not carry an older person through powerful current solely to reach a centre on the other side.
A successful evacuation plan is one that every household member can complete safely.
Children, schools and supervised reunion
A school may remain dry while the access road or a bridge used by buses is inundated.
Staff should follow current education and municipal instructions for safe supervision or evacuation. Parents should use official reunification arrangements rather than travel through flooded roads.
Teach children: “Do not step into water covering the road. Stay with your teacher or adult and use the safe route.”
Children with mobility or medical needs must have individual assistance plans.
Accessible evacuation and medical equipment
A wheelchair user or person reliant on powered medical equipment may need an early transport and backup-power arrangement.
Ask municipal authorities about accessible vehicles and appropriate shelter in advance. Keep prescriptions and relevant medical information accessible.
In an emergency call, describe the exact assistance requirement and current road or staircase conditions.
An evacuation plan cannot rely solely on walking quickly or taking a building lift that may lose electricity.
What goes in a practical flood backpack?
- Essential prescribed medicine, medical records and first aid.
- Identification, important contacts and necessary documents in waterproof wrapping.
- Safe drinking water and ready-to-eat food.
- Mobile phone, power bank, torch, batteries and radio when available.
- Sturdy waterproof footwear, warm clothes and suitable outerwear.
- Infant feeding, hygiene and sanitary supplies.
- Mobility, hearing and vision aids and necessary equipment.
- A written family meeting point and current evacuation destination.
- Keys, some cash and basic pet items where practical.
- Important details about chronic medical care or dependent household members.
The bag should be carryable while assisting another person. Do not return to a dangerous basement for it.
Pets, livestock and farm access
The Polish government advises arranging livestock evacuation early because large animals can require special equipment and more time than human evacuation.
Speak with neighbours and local responders about suitable arrangements before floodwater arrives. Prepare safe feed and animal water where feasible.
Do not delay a mandatory human departure to rescue agricultural equipment or a vehicle. Emergency boats and fire service equipment may not be suited to moving large animals.
Good animal planning reduces the chance of a dangerous last-minute rescue attempt.
Hazardous materials and heating oil tanks
Floodwater may reach pesticides, paints, solvents, fuel or heating oil storage and spread contamination into homes or the environment.
Polish official flood guidance explicitly advises securing dangerous chemicals and tanks before flooding, when it can be done safely.
Do not enter contaminated lower rooms or handle unknown chemical deposits without professional advice.
Floodwater exposed to fuel or chemicals cannot necessarily be made safe by boiling.
Drinking-water safety after flooding
Floodwater may contaminate wells, pipes and storage tanks with sewage or other harmful substances.
The Polish Ministry of Interior warns that well or groundwater may become unsafe. Follow current public-health and water-supplier instructions, and obtain verified safe water.
Boiling may help reduce some microbial hazards when advised, but does not remove many chemical contaminants.
Safe water for infants, cooking and drinking is one of the first priorities after evacuation and immediate rescue.
Sanitation, sewage and infection risks
Flooding can interrupt sewage systems and spread harmful microorganisms. Food or surfaces that contact floodwater may need careful disposal or cleaning.
Use sturdy waterproof footwear and suitable gloves during authorised cleanup. Protect wounds and wash exposed skin with safe water and soap.
Seek healthcare for severe diarrhoea, fever, worsening wounds or other concerning illness following flood exposure.
Health problems can arise after a street looks dry again.
Food safety and refrigeration
Power outages may spoil perishable food. Floodwater can contaminate kitchens and food storage.
Discard unsafe items according to public-health guidance. Do not rely solely on smell or appearance to decide that something remains edible.
Food businesses should check water, electricity, refrigeration and sanitation before reopening.
Commercial stock recovery must not compromise the health of customers or workers.
Electrical and gas safety after water recedes
Electrical panels or appliances exposed to water may be unsafe even after the floor dries.
Do not reconnect affected equipment until qualified personnel assess it. Treat fallen wires as live and remain away from damaged gas fittings.
When fuel-burning generators are used for backup power, operate them outdoors according to manufacturer instructions—never inside a home or closed garage because of carbon monoxide risk.
Restoring utilities requires more than switching them on when the visible water disappears.
Basement cleaning and structural checks
Before entering a flooded cellar, ensure the responsible authorities or qualified professionals have assessed the relevant hazards.
Water may undermine foundations or damage walls, stairs and floors. Significant cracks or sagging elements require structural evaluation.
Do not operate pumps or electrical equipment in standing water without appropriate professional safety arrangements.
A homeowner should not take unnecessary risks to accelerate the drying of an unsafe property.
The first hour after reaching shelter
Account for household members, injuries and urgent medication needs. Find out where drinking water, sanitation and medical help are available.
Notify one trusted contact that the family is safe and identify the next planned communication. Avoid unnecessary journeys into closed areas.
A shelter may need to move residents if the flood or another hazard evolves; follow current instructions.
A safe refuge is a place to coordinate the next protective steps, not a starting point for unauthorised property retrieval.
Flood misinformation and old videos
Photographs from past Polish floods may circulate as though they are live coverage. A genuine river chart may also be copied without its station and timestamp.
Before sharing, verify source, county, river, time and requested action. Use official IMGW, RCB and local authority information.
Do not announce that an entire voivodeship has been evacuated when the order applies only to certain places.
Accurate messages reduce panic, unnecessary travel and congestion on rescue routes.
When can you return?
Wait for the responsible authorities to lift access restrictions. A flood may leave bridges, banks, electrical systems and buildings unstable.
Check your specific property for structural damage, safe water, sewage issues and electrical hazards. A reopened street does not mean every cellar is ready for occupancy.
Do not allow children to play in contaminated mud or enter a house with compromised walls.
The river falling is not the same as complete, safe recovery.
Insurance, documentation and assistance
Once safe access is permitted, record property losses from stable locations. Follow verified insurer and public authority procedures.
Do not enter a structurally unsafe building solely to obtain photographs or documents. Avoid unofficial agents demanding up-front payment for supposedly guaranteed disaster grants.
Keep records of municipal warnings, relocation and relevant repairs where appropriate.
Financial recovery should proceed after the safety of people, utilities and the building has been addressed.
Community flood plans and neighbours
Residents should know who receives official alerts, which route remains safe and who can assist neighbours with limited mobility.
Arrange an out-of-area contact and a backup meeting point. Local authorities may change the location of a shelter if water affects its access.
Where possible before flooding, help vulnerable residents move medicine and essentials. Avoid untrained rescue attempts in fast current.
Community resilience is strongest when the plan removes foreseeable obstacles before water arrives.
Scenario 1: a family on a river floodplain gets an RCB message
Imagine a family near the Odra receiving an RCB SMS and a municipal instruction to evacuate part of their neighbourhood. Their home remains dry, but the only low bridge is at risk.
They prepare essential medicine, follow the designated route and leave before the crossing is closed.
This is a fictional teaching scenario, not a current Poland flood report. Its lesson is acting early while the route is safe.
Scenario 2: water enters an underground garage
A resident sees water rushing down a car-park ramp while an expensive vehicle remains below.
The resident does not descend to move it, informs building management and seeks assistance if people are threatened.
The lesson is basement flooding creates life-safety hazards far beyond vehicle damage.
Scenario 3: a person needs medical rescue
Floodwater traps an older person upstairs. Their family displays a red signal safely and calls 112, giving the exact address, condition and access problem.
They remain in protected refuge instead of attempting to carry the person through current.
The lesson is the official flag can supplement—not replace—an emergency call.
Scenario 4: a rural farm prepares animal evacuation
A farmer receives early warning that the river may overtop local defences. Transporting animals will take longer than moving people.
The farmer coordinates authorised arrangements before the water arrives and does not remain in the flood zone once human evacuation is ordered.
The lesson is early livestock planning protects both animals and people.
Scenario 5: a driver follows a flooded underpass route
A driver’s navigation system shows the normal city route, but an underpass is covered with muddy water.
The driver turns back at a safe location rather than guessing the depth or following another car.
The lesson is a navigation app cannot establish current floodwater or structural conditions.
Scenario 6: a well becomes contaminated
After flooding, a household’s well looks clear again. A family member proposes using it for drinking without checking the official health notice.
The household instead obtains verified safe water and follows the public-health treatment instructions.
The lesson is invisible contamination may remain after sediment settles.
Scenario 7: a bridge appears reopened because the water is gone
Floodwater has receded from a rural crossing but an official barrier remains. Some drivers propose using the bridge anyway.
The group follows the restriction and waits for inspection. The bridge approach may have lost support beneath the road.
The lesson is water recession is not engineering clearance.
Common flood mistakes in Poland
- “A small local flood cannot be dangerous.” Current, electricity and road damage may create serious risks.
- “The nearest IMGW station tells me exact water depth inside my home.” Station levels and local inundation differ.
- “An RCB Alert needs registration or an app.” It does not.
- “No RCB SMS means the road cannot be flooded.” Not every local hazard triggers a national message.
- “An RCB SMS is an evacuation order for the entire country.” Read the affected place and action.
- “A large vehicle can cross water over a bridge.” Current and erosion may undermine it.
- “I can walk through the water instead of driving.” Swift flow and hidden drains remain dangerous.
- “A flooded basement is safe if the main lights are on.” Electricity increases the hazard.
- “I should go downstairs to switch off a wet electrical panel.” Never enter water to operate it.
- “My insurance documents are worth a dangerous return.” Life and safe departure come first.
- “A white flag requests urgent medical treatment.” Poland’s published signal for medical help is red; white means evacuation.
- “A blue flood flag requests police help.” In the official guidance blue signals food or drinking-water needs.
- “A flag guarantees an immediate rescue.” Call 112 and give precise details when possible.
- “A flooded well is safe when the water looks clear.” Contaminants may be invisible.
- “Boiling removes heating oil or pesticides.” It does not remove many chemicals.
- “A quiet afternoon means the river has finished rising.” Upstream water may continue arriving.
- “A road is safe as soon as the floodwater leaves.” Structure and foundation checks may still be necessary.
- “All public shelters are open throughout the event.” Verify current operations and accessibility.
Frequently asked questions
What should I do first if a flood threatens my home in Poland?
Check IMGW and local authority warnings, prepare essentials and evacuate when directed while a safe route remains open. Avoid moving floodwater.
What is Alert RCB?
Poland’s emergency SMS notification system for serious threats. It is sent to mobile phones in affected areas, without registration or app installation.
Where can I check Polish river forecasts?
Use IMGW’s hydrological service and the hydrological warning map, alongside local instructions.
What number should I call for flood rescue?
112 is the general emergency number. The government also lists 998 fire, 999 ambulance and 997 police.
What do the white, red and blue flags mean during flooding?
White means evacuation needed, red means medical assistance needed, and blue means food or water needed, according to Poland’s government safety handbook.
Should I enter a basement to disconnect electricity?
No, not if it is flooded or otherwise dangerous. Isolate utilities only from a safe position with proper guidance.
Is it safe to cross a bridge after floodwater recedes?
Only when the responsible authority permits travel and the route is safe. Foundations or approaches may have been damaged.
Can children remain at school during a flood?
Follow the school’s current supervision and local authority instructions; do not send children home across floodwater.
When is it safe to return to a flood-damaged home?
When local authorities allow access and significant structural, electrical, water and sanitation hazards are addressed.
