Welcome To bagyo.ph – Online Weather Philippine Weather Forecast
Typhoons in the Philippines refer in general to tropical cyclones that enter the Philippine area of responsibility and affect the Philippines. Locally they are called bagyo. Tropical cyclones entering the Philippine area of responsibility are given a local name by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), which also raises public storm signal warnings as deemed necessary. Around 19 tropical cyclones enter the Philippines’ area of responsibility in a typical year and of these usually 6 to 9 make landfall.
The term bagyo, a Tagalog word meaning typhoon arose after a 1911 storm in the city of Baguio had a record rainfall of 46 inches within a 24-hour period
Public Storm Warning Signals
winds of 30–60 km/h (20-35 mph) are expected to occur within 36 hours
winds of 60–100 km/h (40-65 mph) are expected to occur within 24 hours
winds of 100–185 km/h, (65-115 mph) are expected to occur within 18 hours.
winds of at least 185 km/h, (115 mph) are expected to occur within 12 hours.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) releases tropical cyclone warnings in the form of Public Storm Warning Signals. An area having a storm signal may be under:
- PSWS #1 – Tropical cyclone winds of 30 km/h (19 mph) to 60 km/h (37 mph) are expected within the next 36 hours. (Note: If a tropical cyclone forms very close to the area, then a shorter lead time is seen on the warning bulletin.)
- PSWS #2 – Tropical cyclone winds of 60 km/h (37 mph) to 100 km/h (62 mph) are expected within the next 24 hours.
- PSWS #3 – Tropical cyclone winds of 100 km/h (62 mph) to 185 km/h (115 mph) are expected within the next 18 hours.
- PSWS #4 – Tropical cyclone winds of greater than 185 km/h (115 mph) are expected within 12 hours.
These storm signals are usually raised when an area (in the Philippines only) is about to be hit by a tropical cyclone. As a tropical cyclone gains strength and/or gets nearer to an area having a storm signal, the warning may be upgraded to a higher one in that particular area (e.g. a signal #1 warning for an area may be increased to signal #3). Conversely, as a tropical cyclone weakens and/or gets farther to an area, it may be downgraded to a lower signal or may be lifted (that is, an area will have no storm signal).
Classes for preschool are canceled when Signal #1 is in effect. High school classes and below are canceled under Signal #2 and classes for colleges and universities and below are canceled under Signal #3.
