11. What Public Storm Warning Signal (PSWS) is issued by PAGASA if damage to affected communities can be very heavy? A. PSWS #1 B. PSWS #2 C. PSWS #3 D. PSWS #4
Intermittent rains may be expected in at least 36 hours. (When the tropical cyclone develops very close to an area, a shorter lead time of the occurrence of the winds will be specified in the warning bulletin.)
Twigs and branches of small trees may be broken.
Some banana plants may be tilted or uprooted.
Some houses of very light materials may be partially unroofed.
Only very light or no damage may be sustained by areas affected.
Rice crops in flowering stage may suffer significant damage.
When the tropical cyclone intensifies and moves closer, this warning signal number may be upgraded.
The waves on coastal waters may gradually develop and swell.
The people are advised to listen to the latest severe weather bulletin issued by PAGASA every six hours.
Business may be carried out as usual except when floods occur.
Disaster preparedness units are activated to alert status.
PSWS #2
A tropical cyclone will affect an area.
Winds of greater than 60 kph and up to 100 kph may be expected in at least 24 hours.
Some coconut trees may tilt; some of them may break.
Few big trees may be uprooted.
Many banana plants may be downed.
Rice and corn crops may be affected.
A large number of houses made of light materials may be unroofed.
Old galvanized iron roofing may be peeled off.
In general, the winds may bring light to moderate damage to the exposed communities.
The sea and coastal waters are dangerous to small seacraft.
Special attention should be given to the latest position, direction and movement speed, and intensity of the storm as it moves toward an area.
The public especially people traveling by sea and air are cautioned.
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
A tropical cyclone will affect an area.
Winds of greater than 100 kph up to 185 kph may be expected in at least 18 hours.
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 light material houses may be unroofed or destroyed. 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.
The weather condition is dangerous to the communities affected.
The sea and coastal waters will be very dangerous to all seacraft.
Travel is very risky especially by air and sea.
People are advised to seek shelter in strong buildings, evacuate low-lying areas, and stay away from the coasts and riverbanks.
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 generally 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 emergency.
PSWS #4
A very intense typhoon will affect the area.
Very strong winds of more than 185 kph may be expected in at least 12 hours.
Coconut plantations 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.
Damage to affected communities can be very heavy.
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.
The area is very likely to be hit directly by the eye of the typhoon.
As the eye of the typhoon approaches, the weather will worsen continuously, with winds increasing to its strongest coming generally from the north.
A sudden improvement of the weather with light winds will be experienced, which means the area is under the eye of the typhoon.
Depending on the eye’s diameter and movement speed, this improved weather may last for an hour or two.
As the eye moves out of the area, weather conditions will worsen, with strong winds generally coming from the south.
The disaster coordinating councils concerned and other disaster response organizations are now fully responding to emergencies.
