Cyclone Warning: Choosing Shelters Before the Culvert Floods
A cyclone warning gives 36 hours before landfall. A coastal village has 320 residents, including 18 people over 70, six pregnant women and 40 head of livestock. Shelter A is a pucca school 5 km away with capacity for 150 people. Shelter B is a panchayat hall 2 km away with capacity for 200, but its asbestos roof was damaged in the last monsoon and has not been repaired. The only road crosses a culvert that usually floods about 12 hours before landfall. The village has two tractors, one jeep and no ambulance. The sarpanch wants to wait until morning, about 12 hours from now, so that people can finish harvesting. The block office has not yet confirmed that either shelter is open.
1. Decide when and where to evacuate, and justify the timing against the cyclone and the culvert.
Read the worked answer
The evacuation must be complete before the culvert floods and before winds reach about 60 km/h, not at the moment of landfall.
- Timing: with 36 hours available and a culvert that floods around 12 hours before landfall, the safe window is roughly the next 18–24 hours. Waiting 12 hours for harvesting leaves too little margin for 320 people, livestock, and the elderly. Start warning and movement now, aim to clear the village by about 24 hours before landfall, and stop road movement once winds are strong or the culvert is under water. The sarpanch's plan risks trapping the village on the wrong side of the culvert.
- Shelter choice: Shelter A is structurally sound and should be the primary shelter. Shelter B should be used only if the roof is repaired and certified safe, or if it can serve as a short-term staging point in dry weather. An asbestos roof that failed once is not a cyclone shelter.
- Capacity: A holds 150, so the overflow needs a second verified pucca building or transport to a block shelter. Do not pack 320 people into a damaged hall.
The reasoning is that shelter is only useful if it survives the wind, and evacuation is only useful if it happens before the access road closes.
2. List the priority groups and the transport plan, including livestock, using only the two tractors, one jeep and no ambulance.

Priority groups:
- Pregnant women, especially any near term, and anyone with a medical condition needing continuous medicine.
- People over 70 and the bedridden, with one family member each.
- Children and their mothers.
- General population.
- Livestock, moved separately and only if it does not delay people.
Transport plan:
- The jeep is best for the six pregnant women and the most frail elderly, with a volunteer and a first-aid kit. It makes repeated short trips to Shelter A.
- One tractor-trolley carries the elderly, children and luggage in the first run; the second tractor carries people in the next run and then fodder/livestock to a raised area or pre-arranged cattle shelter.
- Fit trolleys with ropes and tarpaulin, keep speeds low, and never overload; count people at loading and at arrival.
- Livestock should not be taken into the human shelter. Identify a raised, government-notified cattle camp; if none exists, move animals to high ground with a few caretakers and return for people first.
The judgement is to use scarce vehicles for people first, because livestock can be moved to high ground while an elderly person cannot walk 5 km in rising wind.
3. The block office has not confirmed the shelters. What should the village team do about verification, warning and records?
Read the worked answer
- Verify before moving: send a two-person team by jeep to Shelter A to confirm it is open, unlock the rooms, check water, toilets, generators and a functioning roof. Report back by phone or messenger. If Shelter A is not open, use the verified pucca building and inform the block office immediately. Do not send 320 people toward an unconfirmed shelter.
- Warn with specific instructions: use the loudspeaker, temple or mosque announcement, ward volunteers and WhatsApp groups. Say the departure time, the pickup point, what to bring (documents, medicines, dry food, torch), and that livestock go separately. Repeat the message.
- Records: keep a household list with names, ages, pregnant women, disabled persons and livestock, and a tally at the shelter. This is how missing people are identified after landfall.
- Escalation: inform the block office in writing that Shelter B is unsafe and that capacity at A is insufficient, and request a second shelter and a medical team.
The reasoning is that an unverified shelter creates a second disaster, and records are the only reliable way to reconcile families after the cyclone.
