When the “eye” of the typhoon hit the community do not venture away from the safe shelter because after one to two hours the worst weather will resume with the very strong winds coming from the south. Disaster preparedness and response agencies/organizations are in action with appropriate response to actual emergency.
If the house is not strong enough to withstand the battering of strong winds, people are advised to go to designated evacuation center or seek shelter in stronger houses, to stay in safe houses until after the disturbances has left the area, to evacuate from low-lying area and riverbanks and stay away from coastal areas for possible flooding and storm surge.
