Process
Public Storm Warning Signals are raised to warn the public of incoming weather disturbances. Once a Storm Signal is raised, conditions are not yet necessarily felt in the given area. The following are the lead times for issuing a Public Storm Signal:
- The weather disturbance is expected in 36 hours once Public Storm Warning Signal No. 1 is raised.
- The weather disturbance is expected in 24 hours once Public Storm Warning Signal No. 2 is raised.
- The weather disturbance is expected in 18 hours once Public Storm Warning Signal No. 3 is raised.
- The weather disturbance is expected in 12 hours once Public Storm Warning Signal No. 4 is raised.
Lead time shortens if a new weather bulletin is issued and the area’s Public Storm Signal Warning remains the same.
As the weather disturbance moves through the Philippine Area of Responsibility (PAR), Public Storm Signals may be upgraded or downgraded.
An area’s given signal number is based on the intensity, size of circulation and the forecast direction, and speed of the tropical storm or typhoon when the Public Storm Warning Signal is raised. Changes in intensity, size of circulation, or movement of the tropical cyclone also determines the change of the Public Storm Warning Signal in a given area.
