What to Do When a Cyclone Warning Is Issued in Bangladesh | Quick Actionable Ideas and Survival Tips

BANGLADESH — A cyclone warning has been issued for your area? Follow the Bangladesh Meteorological Department (BMD), Cyclone Preparedness Programme (CPP) volunteers and local administration. If authorities tell you to evacuate a coastal or low-lying area, leave early for a designated cyclone shelter or other approved safe place. For immediate rescue or life-threatening danger, call 999.

A cyclone can bring destructive wind, heavy rain, storm surge, river flooding and dangerous conditions at sea. The nearest shelter may be impossible to reach after water rises. Do not wait for a visible wave or for the roof to fail before making the decision to move.

12 immediate actions — cyclone warning survival checklist

Check the official warning. Use BMD’s current Special Weather Bulletin, local administration announcements and CPP volunteers.
Understand the instruction for your location. Warning signals, shelter directions and evacuation orders may apply differently to a coastal char, island, fishing harbour or inland town.
Prepare to evacuate early. Families in low-lying homes, near tidal rivers or on isolated islands should not wait until transport routes are flooded.
Give priority to vulnerable people. Help children, pregnant people, older residents, disabled people and anyone needing urgent medicines or accessible transport.
Go to an approved cyclone shelter when instructed. Confirm which shelter is open and the safe route through local authorities or CPP volunteers.
Do not cross dangerous water. Avoid flooding roads, storm-surge channels, unstable bridges and unnecessary boat crossings during severe weather.
Carry a small emergency bag. Bring identity documents, essential medicines, water, dry food, clothing, a torch, phone and power bank if within reach.
Secure the home only while it is safe. Close openings, move essential items above likely water levels and isolate utilities only if accessible without danger.
Keep away from the sea and riverbanks. Do not go fishing, visit the beach or stand beside an exposed embankment during an active cyclone threat.
For immediate danger or rescue, call 999. Give your village, union, upazila, district, landmark, number of people and urgent medical needs. The disaster helpline is 1090.
At the shelter, register and follow staff instructions. Keep children supervised and explain any medical or accessibility requirements.
Do not return immediately after the wind eases. Flooding, damaged power lines, unstable buildings and renewed wind can remain dangerous. Wait for the official all-clear.

If your community is being evacuated now, go as directed. The longer explanations below are intended for preparation or for reading from a safe location.

How cyclone warning information reaches households

The Bangladesh Meteorological Department issues weather bulletins and storm warnings. CPP, a joint programme of the Government of Bangladesh and the Bangladesh Red Crescent Society, helps distribute warnings in coastal communities. CPP volunteers use local communications, public-address systems and other arrangements to relay official information and support evacuation and shelter operations.

CPP describes a graduated approach to signals, including early notice, growing danger and the most serious warning stages. The meaning of the signal and the particular port or community concerned must be understood from the current BMD bulletin and local instruction. A warning number forwarded without a date, location or issuing authority may be misleading.

An official warning does not guarantee that every village has the same wind or water conditions. A coastal island or char may face a storm-surge risk while another town is more affected by rain and falling trees. Follow instructions for your location and treat the condition of the actual route as critical.

Why storm surge can be more dangerous than wind

A storm surge is an abnormal rise in sea level driven by storm winds and pressure. Coastal water can move across low land, through river mouths and into homes. It may cut off the path to a shelter before the strongest winds arrive. Heavy rain and high tides can increase the danger.

For people in exposed coastal regions, elevated roads, embankments and ordinary two-storey homes are not automatically safe substitutes for a designated shelter. An embankment can be overtopped or damaged, and a bridge can become unusable. Local evacuation planning considers land elevation, expected surge, accessibility and the strength of the structure.

Do not walk through fast-moving floodwater to retrieve a fishing net, livestock or boat. Water depth is difficult to judge and debris, open drains and erosion can make a seemingly familiar route dangerous.

Where to find a cyclone shelter in Bangladesh

The Department of Disaster Management (DDM) operates a disaster information system with a shelter map and table, and CPP volunteers and local administration assist residents to reach safe shelters. This information is a starting point, but the fact that a building appears on a list does not prove it is currently open or accessible.

Before cyclone season, ask the local disaster-management committee or CPP team which shelter serves your village and what route should be used. Check whether it can accommodate someone using a wheelchair, a person needing medical support, or a family with small children. Identify a backup if access across a bridge or river becomes unsafe.

When a cyclone is approaching, follow the current directions of authorised local officials. Do not travel to a school simply because it was used as a shelter in a previous storm. Shelter availability, occupancy and routes may change.

What to take when evacuating

Identity documents or securely stored copies, including essential medical details.
Prescription medicine, glasses, sanitary items and any needed disability supplies.
Drinking water, ready-to-eat dry food, a torch and spare batteries if available.
A phone, power bank, and paper emergency contact numbers.
Infant feeding supplies, nappies, warm or dry clothing and a suitable covering.
A small amount of cash if available without delaying departure.
Basic items suitable for the destination shelter, subject to its instructions.

A bag helps only when it is ready before the warning becomes urgent. Do not return from a safe route to search for a missing birth certificate or mobile charger. Tell the shelter or relief team about missing essentials instead.

Families, children, pregnancy and disability

CPP’s shelter operations prioritise people who are more vulnerable, including pregnant women, children, disabled people and those who are ill. This is particularly important when moving people requires a boat, an accessible vehicle or help crossing uneven ground. Arrange transport in advance where possible.

A household should assign a responsible adult to every young child, identify which relative will assist a person with mobility difficulties, and decide who carries essential medications. Do not allow children to wander near embankments or storm drains while adults are loading supplies.

If a person depends on electrical medical equipment, ask their healthcare provider and local authorities about backup plans early. A shelter’s presence does not guarantee that every power outlet, oxygen supply or specialist device will be available. Explain the requirement before the patient is placed at risk.

What to do at home before leaving

If sufficient time remains and conditions are still safe, close windows and doors, secure loose roofing materials and move valuable supplies or documents to higher shelves. Charge phones, fill clean drinking-water containers and protect the emergency bag from rain. These actions must not delay an evacuation order.

Do not climb onto a roof during strong wind to fasten metal sheets. Do not approach fallen electrical wires or operate wet switches. If shutting off electricity or gas would require standing in water, leave the controls alone and tell rescuers or utility workers.

Do not assume that a masonry house offers protection against any level of storm surge or structural damage. Follow the local shelter and evacuation plan rather than relying on a household’s confidence in its construction.

If you are already trapped by rising water

Call 999 for immediate rescue if possible. Provide the most precise location you know: district, upazila, union, village, nearby landmark, road or embankment, the number of people and whether anyone is injured. Explain how high the water is and whether an accessible route remains.

Avoid stepping into moving water. Seek a stable higher place within an appropriate structure if no safe exit remains and follow rescue instructions. Do not take a small boat into dangerous wind or current without a trained crew and a safe route. An attempt to escape can create another casualty.

Preserve your phone battery for emergency calls and keep children together. If a person is missing, give responders the last confirmed location instead of launching an unsafe independent search.

Fishing boats, boats at anchor and coastal workers

BMD provides marine and fishing-related warnings. When authorities instruct fishing vessels to avoid going to sea or return to safe harbour, follow the warning promptly. The exact instruction depends on the current bulletin and the area concerned.

A boat is not made safe by being familiar to its operator. Cyclone winds, wave height and reduced visibility may overwhelm small vessels. Do not take a last trip to retrieve nets or equipment after a warning requires staying ashore.

Coastal employers should release workers in time to reach a safe location. Do not keep people on an exposed worksite to complete a delivery or secure a building when evacuation is needed. Wage concerns can be resolved later; unsafe travel becomes harder as the weather deteriorates.

What happens inside a cyclone shelter

Follow the shelter team’s entry, registration and accommodation instructions. Keep children supervised and tell staff about allergies, medication, pregnancy, mobility limitations or urgent health problems. Store personal documents safely and do not share photos of displaced families or their identification without permission.

Water, toilet capacity and sleeping space may be strained. Use supplies responsibly, follow hygiene arrangements and cooperate with staff about movement within the building. If you need essential medication or clinical support, ask for the designated medical contact rather than leaving the shelter during dangerous weather.

The exact relief provision depends on the location and event. Do not assume financial aid or a particular package of food and supplies is guaranteed solely because you have registered.

When the cyclone seems to have passed

A sudden period of calm can occur near the centre of a cyclone. Conditions may worsen again. Do not leave the shelter based only on a temporary reduction in wind. Wait for the official all-clear and local instructions.

After the storm, flooded roads, contaminated drinking water, damaged bridges, unstable trees and downed power lines may remain. Do not enter a building with suspected structural damage or operate an appliance that was submerged. Seek qualified inspection when essential systems were damaged.

Follow public-health advice about safe drinking water and food. Keep children away from standing water and damaged electrical infrastructure. Record damage from safe locations for official assistance or insurance. Ask local authorities about recovery support and avoid sharing rumours about aid eligibility.

Frequently asked questions

What is the emergency number during a cyclone in Bangladesh?

The Department of Disaster Management lists 999 for national emergency assistance and 1090 as the disaster helpline. Use 999 for a life-threatening emergency or immediate rescue.

Where can I find official cyclone warnings?

Check the Bangladesh Meteorological Department Special Weather Bulletin and relevant announcements from local authorities and CPP volunteers.

Do I have to wait until the strongest warning signal to leave?

No. Follow local evacuation directions. People in exposed or hard-to-reach areas may need to leave earlier so routes do not become inaccessible.

Is every school a cyclone shelter?

No. Confirm the currently designated and open shelter through local officials, CPP volunteers or the DDM shelter information service.

Can I cross shallow storm-surge water?

Do not cross dangerous moving or uncertain water. It can conceal erosion, debris and currents even when the surface looks manageable.

Can I return home as soon as the wind stops?

No. A lull is not an all-clear, and flooding and infrastructure damage can remain. Wait for authorised local guidance.

Remember the essential sequence

Check BMD and CPP warnings. Leave vulnerable coastal areas early when directed. Use approved cyclone shelters. Do not cross floodwater. Call 999 for rescue. Return only after clearance.
