IMPACT OF THE WINDS: Twigs and branches of small trees may be broken. Some banana plants may be tilted or downed. Some houses of very light materials (nipa and cogon) may be partially unroofed. Unless this warning signal is upgraded during the entire existence of the tropical cyclone, only very light or no damage at all may be sustained by the exposed communities. Rice crop, however, may suffer significant damage when it is in its flowering stage. PRECAUTIONARY MEASURES: When the tropical cyclone is strong or is intensifying and is moving closer, this signal may be upgraded to the next higher level. The waves on coastal waters may gradually develop and become bigger and higher. The people are advised to listen to the latest severe weather bulletin issued by PAGASA every six hours. In the meantime, business may be carried out as usual except when flood occur. Disaster preparedness is activated to alert status.

IMPACT OF THE WINDS: Some coconut trees may be tilted with few others broken. Few big trees may be uprooted. Many banana plants may be downed. Rice and corn may be adversely affected. Large number of nipa and cogon houses may be partially or totally unroofed. Some old galvanized iron roofings may be peeled off. In general, the winds may bring light to moderate damage to the exposed communities. PRECAUTIONARY MEASURES: The sea and coastal waters are dangerous to small seacrafts Special attention should be given to the latest position, the direction and speed of movement and the intensity of the storm as it may intensify and move towards the locality. The general public especially people travelling by sea and air are cautioned to avoid unnecessary risks. Outdoor activities of children should be postponed. Secure properties before the signal is upgraded. Disaster preparedness agencies / organizations are in action to alert their communities. PSWS # 3 METEOROLOGICAL CONDITIONS: A tropical cyclone will affect the locality. Winds of greater than 100 kph up to 185 kph may be expected in at least 18 hours. IMPACT OF THE WINDS: Many coconut trees may be broken or destroyed. Almost all banana plants may be downed and a large number of trees may be uprooted. Rice and corn crops may suffer heavy losses. Majority of all nipa and cogon houses may be unroofed or destroyed and there may be considerable damage to structures of light to medium construction. There may be widespread disruption of electrical power and communication services. In general, moderate to heavy damage may be experienced, particularly in the agricultural and industrial sectors. PRECAUTIONARY MEASURES: The disturbance is dangerous to the communities threatened/affected. The sea and coastal waters will be very dangerous to all seacrafts. Travel is very risky especially by sea and air. People are advised to seek shelter in strong buildings, evacuate low-lying areas and to stay away from the coasts and river banks. Watch out for the passage of the eye of the typhoon indicated by a sudden occurrence of fair weather immediately after very bad weather with very strong winds coming gnerally from the north. 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. Classes in all levels should be suspended and children should stay in the safety of strong buildings. Disaster preparedness and response agencies/organizations are in action with appropriate response to actual emergency. PSWS # 4 METEOROLOGICAL CONDITIONS: A very intense typhoon will affect the locality. Very strong winds of more than 185 kph may be expected in at least 12 hours. IMPACT OF THE WINDS: Coconut plantation may suffer extensive damage. Many large trees may be uprooted. Rice and corn plantation may suffer severe losses. Most residential and institutional buildings of mixed construction may be severely damaged. Electrical power distribution and communication services may be severely disrupted. In the overall, damage to affected communities can be very heavy. PRECAUTIONARY MEASURES: The situation is potentially very destructive to the community. All travels and outdoor activities should be cancelled. Evacuation to safer shelters should have been completed since it may be too late under this situation. With PSWS #4, the locality is very likely to be hit directly by the eye of the typhoon. As the eye of the typhoon approaches, the weather will continuously worsen with the winds increasing to its strongest coming generally from the north. Then a sudden improvement of the weather with light winds (a lull) will be experienced. This means that the eye of the typhoon is over the locality. This improved weather may last for one to two hours depending on the diameter of the eye and the speed of movement. As the eye moves out of the locality, the worst weather experienced before the lull will suddenly commence. This time the very strong winds will come generally from the south. The disaster coordinating councils concerned and other disaster response organizations are now fully responding to emergencies and in full readiness to immediately respond to possible calamity.
