Scattered Rainshowers and Thunderstorms Forecast Across Northern Luzon

According to PAGASA in its official forecast released at 5:00 AM on June 12, 2026, Northern Luzon is expected to experience partly cloudy to at times cloudy skies with scattered rainshowers or thunderstorms. The state weather bureau reported that these weather conditions are accompanied by light to moderate winds blowing from the southwest, creating slight to moderate wave conditions along the seaboards.

For residents in La Union, this forecast means preparing for sudden rain and potential thunderstorms throughout the day. Local temperatures in the province are expected to hover between 25°C and 33°C, which may bring warm and humid conditions interrupted by sudden downpours.

The PAGASA Regional Services Division officially ended Thunderstorm Advisory No. 9 at 7:40 AM on June 12, signaling a temporary decrease in severe storm activity. However, weather specialists emphasize that localized rainshowers can still develop rapidly, presenting sudden risks to low-lying and mountainous areas.

Local disaster risk reduction offices advise residents living near mountain slopes in La Union to remain alert for signs of landslides, mudslides, and rockslides. Similarly, those residing near rivers and waterways should monitor water levels due to the threat of sudden flash floods during intense rain.

The extended weather outlook from PAGASA shows that these weather patterns will likely continue over the next five days. From June 12 to June 15, 2026, temperatures in the region are projected to range from 24°C to 34°C, with southwest winds and slight to moderate coastal waters remaining constant.

Fishermen and small sea vessel operators in La Union are advised to exercise caution, as light to moderate winds can still cause unexpected wave surges during localized thunderstorms. The public is urged to keep monitoring official weather updates for any sudden changes in rainfall warnings.
