The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) releases tropical cyclone warnings in the form of tropical cyclone warning signals. On March 23, 2022, PAGASA revised definition of super typhoon, signal system. An area having a storm signal may be under:

  • TCWS #1 – Tropical cyclone winds of 39 km/h (24 mph) to 61 km/h (38 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.)
  • TCWS #2 – Tropical cyclone winds of 62 km/h (39 mph) to 88 km/h (55 mph) are expected within the next 24 hours.
  • TCWS #3 – Tropical cyclone winds of 89 km/h (55 mph) to 117 km/h (73 mph) are expected within the next 18 hours.
  • TCWS #4 – Tropical cyclone winds of 118 km/h (73 mph) to 184 km/h (114 mph) are expected within 12 hours.
  • TCWS #5 – Tropical cyclone winds greater than 185 km/h (115 mph) are expected within 12 hours.

These tropical cyclone warning 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 No. 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 No. 1 is in effect. Elementary and high school classes and below are canceled under signal No. 2 and classes for colleges, universities and below are canceled under signal Nos. 3, 4 and 5.
