TL;DR
Over the past 10 days, Habagat and several cyclones have brought an average of 483 mm of rain to Metro Manila. This has caused flooding and transportation disruptions. The situation remains ongoing with weather forecasts predicting continued rain.
Metro Manila has experienced an average rainfall of 483 millimeters over the past 10 days due to the combined effects of the southwest monsoon, known locally as Habagat, and several active cyclones, according to Inquirer.net. This significant volume of rain has resulted in widespread flooding, transportation disruptions, and local emergency responses, making it a critical weather event for the region.
Data from the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) confirms that the rainfall levels in Metro Manila over the past 10 days have averaged 483 mm, surpassing typical seasonal amounts. The intense rainfall is attributed to the persistent southwest monsoon, Habagat, which has been reinforced by the passage of multiple cyclones in the region, including Typhoon Egay and Typhoon Falcon.
Local authorities have reported flooding in several areas, with some streets submerged under water, affecting thousands of commuters and residents. According to the Metropolitan Manila Development Authority (MMDA), at least 15 major roads were temporarily closed due to flooding, and several barangays have declared localized evacuation centers. No fatalities have been reported, but property damage and infrastructure strain are significant concerns.
Weather forecasts indicate that the rainy conditions are expected to persist over the coming days, with PAGASA warning of continued heavy rainfall and possible flash floods, especially in low-lying and flood-prone areas.
Impacts of Prolonged Heavy Rainfall in Metro Manila
The sustained heavy rainfall over the past 10 days underscores the increasing frequency and intensity of weather events linked to climate variability. The flooding and transportation disruptions threaten public safety and economic activity, highlighting the need for improved disaster preparedness and resilient infrastructure. The ongoing weather pattern also raises concerns about future flood risks during the rainy season, especially if such rainfall levels become more common.

Recent Weather Patterns and Cyclone Activity in the Region
Metro Manila’s weather has been heavily influenced by the southwest monsoon, Habagat, which typically brings heavy rains during the rainy season. Over the past month, PAGASA has recorded several tropical cyclones passing near or over the Philippines, including Typhoon Egay and Typhoon Falcon, which contributed to the cumulative rainfall. Historically, such prolonged heavy rainfalls are associated with increased flooding and landslides, especially in urban areas with inadequate drainage systems.
This recent event is part of a pattern of intensified weather disturbances in Southeast Asia, linked to broader climate change trends. Authorities have been monitoring these developments closely to mitigate impacts and prepare for potential emergencies.
“The combination of Habagat and multiple cyclones has resulted in rainfall totals exceeding normal levels for this period, with some areas experiencing more than 500 mm of rain.”
