The Philippine Atmospheric, Geophysical and Astronomical Services Administration reported an intense thunderstorm affected the northern portion of Metro Manila and western Rizal on Saturday afternoon. Heavy to intense rainshowers with lightning and strong winds were experienced in southern Metro cities including Muntinlupa, Parañaque, Las Piñas, and Pasay.
Pagasa's thunderstorm advisory warned the severe weather could persist for one to two hours. The state weather bureau urged residents to take precautionary measures against potential flash floods and landslides. "Localized thunderstorms are expected," a Pagasa forecaster stated in the bulletin.
The weather disturbance also threatens five specific areas in Luzon according to Pagasa's latest forecast. These include Tarlac municipalities San Jose, Capas, and Bamban, along with Santa Cruz in Zambales and Gabaldon in Nueva Ecija. These regions should prepare for similar conditions.
For Metro Manila and the rest of the country, partly cloudy to cloudy skies with isolated rainshowers or thunderstorms are predicted. The primary weather system causing these conditions is localized thunderstorms, not a low-pressure area or monsoon surge. This makes forecasting precise locations challenging.
Possible flash flooding remains a significant concern in low-lying and flood-prone areas. Pagasa emphasizes that during severe thunderstorms, the public should seek shelter, avoid open fields, and refrain from using electrical appliances. Lightning poses a serious threat during these events.
Local government units in affected areas have been alerted to monitor situations closely. Disaster risk reduction management councils are on standby to respond to any emergencies. Rapid water level rises in creeks and drainage systems are possible.
The thunderstorm activity is typical for the current transitional weather period. Pagasa notes that warm, humid afternoons often trigger convective development leading to such intense but localized rainfall. These patterns are expected to continue in coming days.
Residents are advised to stay updated through official Pagasa channels for real-time thunderstorm advisories. The bureau issues updates every few hours when significant convective development is detected by radar and monitoring stations across the archipelago.
Transportation may be affected in flooded areas, particularly in Metro Manila's known flood hotspots. Commuters should anticipate possible delays and rerouting. Visibility can drastically reduce during periods of intense rainfall.
Pagasa continues to monitor broader weather systems, but confirms no tropical cyclone is currently enhancing thunderstorm activity. The forecast for the next 24 hours maintains the chance of isolated to scattered rainshowers, primarily during afternoon and evening hours.
