EL SALVADOR CITY, Misamis Oriental — Large parts of Mindanao are expected to experience unsettled weather conditions on Saturday, August 8, with partly cloudy to cloudy skies, isolated rainshowers and localized thunderstorms prevailing across the region, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

The Mindanao Regional Weather Forecast (MINPRSD), issued at 5:00 a.m. on August 8, covers the period from 5:00 a.m. Saturday until 5:00 a.m. Sunday, August 9.
PAGASA warned that some thunderstorms could become severe enough to trigger flash floods and landslides, particularly in areas that receive intense or prolonged rainfall.
The weather agency also forecast moderate to strong winds from the southwest, accompanied by moderate to rough seas ranging from 1.2 to 2.8 meters, raising concerns for sea travel, fishing activities and communities in exposed coastal areas.
Thunderstorms to affect wide areas
Across Mindanao, skies are generally expected to remain partly cloudy to at times cloudy, with rainshowers or thunderstorms occurring in different areas throughout the forecast period.
The combination of localized thunderstorms and strong southwest winds means that weather conditions may change rapidly, with periods of sunshine potentially followed by sudden heavy rain, gusty winds and thunderstorms.
PAGASA’s warning regarding possible flash floods and landslides is particularly important for communities near rivers, streams, steep slopes and other flood- or landslide-prone areas.
Residents are urged to remain alert during thunderstorms and to avoid crossing swollen rivers and waterways when heavy rain occurs.

Public urged to exercise caution
With thunderstorms forecast across virtually all parts of Mindanao, authorities and residents are advised to closely monitor weather developments, particularly during periods of darkening skies, strong winds and intense rainfall.
PAGASA’s warning that severe thunderstorms could cause flash floods and landslides underscores the need for heightened preparedness, especially in communities located near waterways, steep terrain and other hazard-prone areas.
Motorists should exercise extra caution on roads during heavy downpours because sudden flooding and reduced visibility can make travel dangerous.
Fishermen and small boat operators are likewise advised to assess sea and wind conditions before venturing offshore, as moderate to rough seas of 1.2 to 2.8 meters are expected across Mindanao’s coastal waters.
Residents are encouraged to monitor official PAGASA bulletins and advisories and to follow instructions from local disaster risk reduction and management offices should hazardous weather develop.
