Metro Manila recorded 186 millimeters of rainfall within a 23-hour span due to the southwest monsoon, known locally as habagat, according to the Metropolitan Manila Development Authority (MMDA) on Sunday.

The rainfall measurement was tracked by the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), the country's official weather agency. The data reflects the intensity of the monsoon system as it swept across the capital region.

The habagat typically brings heavy rains to the western portions of the Philippines during the months of June through September. Metro Manila, situated on the western coast of Luzon, is particularly susceptible to monsoon-driven precipitation during this period.

With such substantial rainfall recorded in a single day, residents and local government units remain alert to potential flooding and waterlogging in low-lying areas. The MMDA continues to monitor weather conditions and coordinate with other agencies to ensure public safety during the ongoing monsoon season.
