The Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) raised a red rainfall warning over parts of Luzon on Wednesday afternoon as the enhanced southwest monsoon, locally known as the habagat, intensified across the region.

The alert was issued in Pagasa's 2 p.m. weather advisory, indicating that rainfall in the affected areas could reach levels that pose significant risks to communities. Red rainfall warnings represent the highest alert status and typically precede warnings of flooding and landslides in vulnerable locations.

The enhanced southwest monsoon has been bringing moisture-laden winds across much of Luzon, resulting in widespread precipitation since earlier in the week. Weather officials advised residents in the warning zones to remain alert and prepared for potential flooding, particularly in low-lying areas and near riverbanks.

Authorities urged the public to monitor updates from Pagasa and local government units for any changes to the weather situation. Communities in the affected regions were advised to take precautionary measures and avoid unnecessary travel during the heavy rainfall period.
