(CNN Philippines) — After days of grueling summer heat, the National Capital Region (NCR) and nearby areas were caught off guard when strong winds and heavy rain poured down on the afternoon of Tuesday (April 21), causing flooding in some areas.
The extremely hot weather caused the sudden downpour, according to Gener Quitlong, a forecaster of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
The high temperature caused water to evaporate quickly until it turned into cumulonimbus clouds, he said in a phone interview on Tuesday with CNN Philippines’ Roanna Jamir.
Thunderstorms are common in hot weather and it usually happens anytime from the afternoon until the evening.
Based on PAGASA’s 3D doppler radar, parts of Metro Manila, Cavite, Rizal, Laguna, Batangas, Pampanga, and Tarlac may continue to experience thunderstorms on Tuesday.
Some netizens said that, aside from rain, ice pellets were also part of the downpour.
