Philippines: Tropical Storm Son-Tinh triggers flooding in Manila July 17

Event

Now-Tropical Storm Son-Tinh (known locally as "Henry") brought heavy rains and flooding to Metro Manila and adjacent provinces on Tuesday, July 17, prompting President Rodrigo Duterte to suspend work in government institutions and academic classes in public schools in the capital for the day. The flooding also reportedly caused traffic disruptions in Manila, particularly in Makati district, and forced the evacuations of people in low-lying areas of Marikina city (Metro Manila). Flooding has also affected parts of northern Luzon, Palawan, and Mindoro.

Though Son-Tinh has since moved out of the Philippine Area of Responsibility, monsoon storms are still forecast to bring heavy rain to Manila and other areas in the Philippines over the coming days, including to the provinces of Zambales, Bataan, Cavite, Batangas, and Palawan, as well as to the islands of Mindoro and the Western Visayas. Consequent transportation disruptions and power outages are possible in affected areas.

Context

Typhoons and tropical storms regularly strike the Philippines during the monsoon season - which typically spans from November to April in the northeast, and from May to October in the southwest. On average, roughly 20 typhoons and tropical storms hit the country each year.

Advice

Individuals in the Philippines are advised to follow all instructions as issued by local authorities (e.g. possible evacuation orders), follow local weather forecasts, and verify travel plans prior to setting out. In the event of further flooding, remember that driving or walking through running water can be dangerous; 15 cm (6 in) of running water is enough to knock over an adult.
