State weather bureau PAGASA has formally marked the onset of the southwest monsoon, or habagat, a familiar seasonal phenomenon that Filipinos deal with year in and year out. As reported by Philstar Biz , the announcement signals the country's transition into the rainy season.

The southwest monsoon typically brings heavy rainfall to many parts of the Philippines, particularly the western regions. PAGASA's declaration serves as an official reminder for the public and various sectors to prepare for potential flooding, landslides, and other weather-related disruptions.

As the country shifts from the dry season to the wet season, government agencies and local disaster risk reduction offices are expected to ramp up monitoring and response efforts. The onset of the habagat also affects agriculture, transportation, and daily activities across the archipelago.
