Northern Luzon to Experience Rainshowers and Thunderstorms

PAGASA says, Northern Luzon will experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms today, July 20, 2026, due to prevailing southwest wind flows. The state weather bureau issued this regional forecast at 5:00 AM, warning of potential localized thunderstorms that may bring light to moderate winds and slight to moderate coastal waters across the region.

In La Union, residents can expect temperatures ranging from 25°C to 32°C throughout the day. The southwest winds will remain light to moderate, keeping coastal waters generally safe but slightly wavy. While La Union is currently spared from the severe thunderstorm advisories affecting neighboring provinces, local disaster offices advise residents to remain alert for sudden weather changes.

The latest weather updates for the region include:

• Ilocos Sur and Abra: Moderate to occasionally heavy rainshowers, lightning, and strong winds are affecting towns such as Santo Domingo, San Ildefonso, and Bangued.
• Ilocos Norte: A thunderstorm watch remains active, indicating a high likelihood of thunderstorm development.
• Coastal Waters: Slight to moderate sea conditions are expected across the Ilocos Region, with winds blowing from the southwest to south.

PAGASA advises residents in mountainous areas of Northern Luzon to monitor for potential flash floods or landslides during heavy rainshowers. The agency will continue to update its daily forecasts and thunderstorm advisories as weather conditions develop.
