PAGASA announced that the Southwest Monsoon is currently influencing Luzon and the western section of Visayas, bringing various weather conditions across these regions as of its 4:00 AM bulletin on June 2, 2026. This weather system is expected to cause rains and thunderstorms, posing risks of flash floods and landslides in affected areas.

Specifically, Zambales, Bataan, Cavite, Batangas, and Occidental Mindoro are forecast to experience occasional rains. Residents in these provinces should be vigilant as these conditions carry a possible risk of flash floods or landslides due to moderate to heavy rainfall.

For Metro Manila, the rest of Luzon (including La Union), and Western Visayas, cloudy skies with scattered rains and thunderstorms are expected throughout the day. This means that communities across La Union, from coastal towns like San Juan to inland areas, should anticipate intermittent rainfall. Residents in areas such as San Fernando City and other municipalities are advised to prepare for moderate to at times heavy rains, which could lead to localized flooding or landslides, particularly in low-lying or mountainous zones.

The remaining parts of the country will generally experience partly cloudy to cloudy skies, with isolated rainshowers or thunderstorms. These localized thunderstorms can also intensify, bringing the potential for sudden flash floods or landslides.

Regarding wind and coastal conditions, Extreme Northern Luzon, which encompasses the northern areas of La Union, will have moderate winds blowing from the southwest. This will result in coastal waters that are moderate, with wave heights estimated between 1.2 to 2.5 meters. Mariners and coastal communities in these areas are advised to take necessary precautions.

For the rest of the country, winds will be light to moderate, generally from the southeast to southwest. This will lead to slight to moderate coastal waters, with wave heights ranging from 0.6 to 2.5 meters.
