2016 Philippine southwest monsoon floods


In August 2016, southwest monsoon has brought heavy rainfall and flooding in Metro Manila and nearby regions.

Background

A low pressure area which barely entered the Philippine area of responsibility, which at one point was north of Batanes and exited the country by August 14, as well as tropical depression located in the Pacific Ocean outside the PAR enhanced the southwest monsoon.

Impact

In August 14, 2016, the National Disaster Risk Reduction and Management Council reported that about 70,000 people or 15,665 families were affected by the enhanced monsoon rains in the regions of Central Luzon, Calabarzon, Mimaropa, Western Visayas, Negros Island Region, Autonomous Region in Muslim Mindanao, and the National Capital Region. Occasional rains were also experienced by residents in areas situated in the rest of Luzon and Visayas. The most affected provinces were reportedly Bataan, Bulacan, and Zambales.
The enhanced monsoon caused a tornado to spawn in Manila's port area causing damages.
At five were reported dead from the floods.

Response

The Department of Social Welfare and Development has opened at least 79 evacuation centers across the island of Luzon. In Marikina, Metro Manila, where the Marikina River overflowed due to enhanced monsoon rains, 21 evacuation centers were set up where at least 9,152 people were housed.
Maynilad which serves significant portions of Metro Manila has reduced its water production due to sedimentation of raw water at the La Mesa watershed due to the monsoon rains causing soil erosion in the Angat watershed.
