Aerial footage from the Philippine Coast Guard showed severe flooding in several towns in the Cagayan Valley region, north of Manila, while rescue efforts continue for the affected residents.
Accumulated effects of previous weather disturbances, as well as water from a dam and higher plains brought high flooding to Cagayan province, the disaster agency said.
The nearby Magat Dam released water on Friday (November 13) equivalent to two Olympic-size pools per second, government data showed.
Vamco, the 21st cyclone to hit the Philippines this year, has killed at least 42 people. It tore through the main island of Luzon late on Wednesday (November 11).
