MANILA, Philippines – A warning system that will indicate the amount of rainfall in a specific area is in the works, weather bureau PAGASA said.

PAGASA officer-in-charge and Department of Science and Technology (DOST) Undersecretary Graciano Yumul told dzMM the bureau is working on calibrating the 5 Doppler radars in the country to allow a forecast of rainfall amount in a specific area.

The weather chief explained the intensity warning will come in 3 classifications: black for heavy rain; red for moderate; and yellow for light.

“Kunwari yung Quezon [at] Aurora parehas silang nasa signal number 1 pero mas malapit ang mata ng bagyo sa Quezon. Then Quezon is black, tapos yung Aurora siguro is red,” Yumul said.

Yumul said the calibration is expected to be finished by January next year.

Risk maps

Yumul asked local government officials to take advantage of the new warning system by coming up with risk maps in their respective areas in order to avoid possible loss of lives.

He explained risk maps will determine which areas are vulnerable from flash floods and landslide within a given rainfall intensity.

He added the creation of these maps should be based on the geo-hazard map released by the national government.

“Yung sinasabi natin sa ating mga kasama na yung buong Pilipinas, may geohazard map na. Ibig sabihin alam na natin kung saan magbabaha, kung saan magla-landslide. Pero kailangan yung mga local government units natin, dapat may risk map sila,” he said.

“Kapag tinignan mo sa mandato, yun ang mandato ng LGUs. Ibibigay ng national [government] ang geohazard map. Sasabihin niya dito ang mga ilog na magbabaha, pero kung sa ganitong ulan, alin dyan ilog ang babaha, yun yung dapat madetermine ng ating mga LGUs," he added.

The budget in making the maps will be sourced from the 5% of the LGU’s calamity fund.
