The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) is working on a warning system that will provide information on the amount of rainfall for a specific area, according to a DZMM interview on PAGASA officer-in-charge and Department of Science and Technology (DOST) Undersecretary Graciano Yumul on Tuesday, October 25, 2011.

USec Yumul revealed that PAGASA is now calibrating the five Doppler radars in the country so that it can be used to forecast the amount of rainfall in a specific area. The Dopplers are expected to be ready by January 2011.

Below is the list of PAGASA classification of the different rainfall intensity warning that will be provided by the new system.

  • Black for heavy rain,
  • Red for moderate, and
  • Yellow for light.

PAGASA is encouraging all local government officials to provide them with geo-hazard risk maps of their respective areas. The risk maps, according to USec Yumul will help identify the areas vulnerable to flash floods and landslide based on a given rainfall intensity. Five percent of the LGU calamity fund will be set aside for the generation of risk maps.
