Public storm warning signals are activated to alert the public of impending weather disruptions. Circumstances are not yet typically perceived in the designated region after triggering a Storm Signal.
The advance times for issuing a public storm signal are as follows:
● Once Public Storm Warning Signal No. 1 is activated, the weather disturbance is anticipated in 36 hours.
● Once Public Storm Warning Signal No. 2 is activated, the weather disturbance is anticipated in 24 hours.
● Once Public Storm Warning Signal No. 3 is activated, the weather disturbance is anticipated in 18 hours.
● Once Public Storm Warning Signal No. 4 is activated, the weather disturbance is anticipated in 12 hours.
The lead time is shortened if a new weather report is released and the local Public Storm Signal Warning stays the same.
Public Storm Signals may change in strength as the weather disturbance passes through the Philippine Area of Responsibility (PAR).
When the Public Storm Warning Signal is raised, a specific location is assigned a signal number depending on the strength, size of circulation, anticipated direction, and speed of the tropical storm or typhoon.
Changes also influence the modification of the Public Storm Warning Signal in a specific location in the tropical cyclone's strength, area of circulation, or motion.
Public Storm Warning Signal No. 1
→ Conditions Meteorologically:
● A tropical cyclone will endanger or impact a region.
● Winds of 30 to 60 kph are anticipated.
● Rain that comes and goes might be anticipated for at least 36 hours. (Whenever the tropical cyclone develops quite close to a region, the warning advisory will provide a reduced lead time frame of the appearance of the winds.)
→ The Effects of the Winds:
● Small trees' twigs and branches could break.
● Some banana plants could have been uprooted or tilted.
● Some exceptionally light-weight homes could have some of their roofs missing.
● Areas impacted may only experience minimal or no harm.
● Rice harvests that are in the blossoming stage might sustain serious harm.
→ Protective Measures:
● This warning signal number could be upgraded as the tropical storm intensifies and approaches.
● In coastal seas, waves may gradually grow and develop.
● Every six hours, PAGASA issues a severe weather bulletin, and the public is recommended to listen to it.
● Unless there are floods, the business may continue as usual.
● The alert status of the disaster preparedness units is activated.
Public Storm Warning Signal No. 2
→ Conditions Meteorologically:
● A tropical cyclone has an impact on a region.
● In at least 24 hours, winds of at least 60 kph and as much as 100 kph may be anticipated.
→ The Effects of the Winds
● Some coconut trees could lean; others might even break.
● Some large trees might be uprooted.
● There may be several felled banana plants.
● It might impact crops of rice and corn
● There may be a lot of light-material homes without roofs.
● Peeling off old galvanized iron roofing is possible.
● The exposed neighborhoods may suffer minor to severe damage from the winds.
→ Protective Measures:
● Small sea crafts are at risk in the ocean and coastal seas.
● As the storm approaches a location, it should pay particular attention to its most recent position, direction, movement speed, and intensity.
● The general population is advised, especially those who travel by air and water.
● Should postpone children's outside activities.
● Before the signal is enhanced, secure the properties.
● Disaster preparedness groups and agencies are working to inform their local populations.
Public Storm Warning Signal No. 3
→ Conditions Meteorologically:
● A tropical cyclone has an impact on a region.
● In at least 18 hours, winds of more than 100 kph and up to 185 kph could be anticipated.
→ The Effects of the Winds:
● There may be many broken or dead coconut trees.
● Many trees might be uprooted and could destroy Almost all banana plants
● Corn and rice harvests might sustain significant losses.
● Most homes made of light materials might lose their roofs or be demolished. Light to medium-weight buildings may sustain significant damage.
● Electrical power and communication services might be severely disrupted.
● In general, moderate to severe damage may occur, especially in the industrial and agricultural sectors.
→ Protective Measures:
● The impacted communities are at risk due to the weather.
● All seacrafts will be in highly unsafe conditions in the ocean and coastal waterways.
● Traveling is exceedingly dangerous, particularly by air and water.
● People are urged to take refuge in sturdy structures, leave low-lying regions, and keep away from riverbanks and coastlines.
● Be on the lookout for the passing of the typhoon's eye, which is characterized by an abrupt change from severe weather to good weather, with extremely high winds often coming from the north.
● Do not leave the secure shelter when the typhoon's eye hits the area; the worst weather will return in one to two hours with mighty winds coming from the south.
● All levels of classes should be canceled, and kids should stay within secure structures for their protection.
● Emergency response and preparedness agencies and groups are working to respond to emergencies correctly.
Public Storm Warning Signal No. 4
→ Conditions Meteorologically:
● There will be a powerful storm in the region.
● More than 185 kph of extremely severe winds may be anticipated in the next 12 hours.
→ The Effects of the Winds
● Plantations of coconuts may sustain significant harm.
● Several giant trees might be uprooted.
● Plantations of rice and corn might sustain significant losses.
● The majority of mixed-construction residential and educational buildings may sustain significant damage.
● The distribution of electrical power and communication services might be seriously affected.
● Communities that are impacted may sustain significant harm.
→ Protective Measures:
The scenario has the potential to be quite harmful to the neighborhood.
● There should be no travel or outdoor activity.
● It ought to have been finished with the evacuation to safer shelters.
● The typhoon's eye is quite likely to strike the region immediately.
● The weather will continue to deteriorate as the typhoon's eye draws closer, with winds becoming more robust and more often originating from the north.
● The region will witness an abrupt weather improvement with mild winds, indicating that a typhoon is approaching the area.
● This better weather may endure for an hour or two, depending on the eye's diameter and rate of movement.
● Weather conditions will deteriorate as the eye leaves the region, with strong winds typically coming from the south.
● Emergency responses are currently being made in full by the relevant disaster coordinating councils and other disaster response agencies.
Super Typhoon:
→ Weather Conditions:
● A Super Typhoon will impact the region.
● In at least 12 hours, highly severe winds with speeds more than 220 kph are possible.
→ The Effects of the Winds:
● Light-weight constructions are almost wholly destroyed, especially in exposed coastal locations.
● Many structures' roofs have entirely failed. Substantial and severe damage to the windows and doors.
● The majority of mixed-construction residential and institutional buildings may sustain significant damage.
● Communication services and the provision of electricity were both significantly affected.
● All billboards were destroyed.
● Banana farm has sustained complete devastation.
● The majority of large trees are damaged, uprooted, or defoliated.

Comments:
Any time a Public Storm Warning Signal Number is raised or initially placed into use, the appropriate meteorological conditions are not yet in effect in the area. This is so that users can be warned when specified weather conditions occur.
It should be remembered that each signal number only has a reasonable approximate lead time for the range of wind speeds when the signal number is initially placed into operation.
