Do not go out when storm number 3 is making landfall.

The Department of Dyke Management and Natural Disaster Prevention (Ministry of Agriculture and Environment) recommends that people in localities monitor forecasts, warnings, and updates on storm developments to proactively prevent and avoid them.

For ships, it is necessary to enter places with ports and waterways. In case there are no ports, they can enter sheltered river channels to anchor.

Absolutely do not stay on anchored boats, tourist boats, watchtowers, rafts, or aquaculture areas when a storm hits.

On land, it is necessary to reinforce and brace houses, prune tree branches, remove potentially unsafe billboards and posters, and ensure the safety of construction sites.

Absolutely do not go out when the storm is making landfall, except in emergency cases and with specific instructions from authorities.

People identify the safest shelter for all family members and proactively evacuate when necessary or as requested by local authorities. Proactively stock up on food, drinking water, medicine, and necessary supplies.

To prevent rain, floods, and inundation in low-lying areas and urban areas, people need to raise their assets, keep important documents in safe places, and move their vehicles to higher terrain.

Also save emergency phone numbers for use in case of emergency.
