Bulacan provincial Gov. Wilhelmino M. Sy-Alvarado said a 70-year-old man died of a heart attack when the roof of his house was blown away.
Nueva Ecija Gov. Aurelio Umali told DZMM radio that fallen trees and electric pylons blocked all the major roads in the province. He said the initial estimate was that 15,000 hectares (37,050 acres) of rice may have been damaged or destroyed.
Sy-Alvarado said more than 20 villages remained flooded Saturday, with some areas under about 2 meters (6 feet) of water. He said about 10,000 hectares (24,700 acres) of rice and vegetable farms were damaged.
A major highway in Bulacan was flooded and authorities allowed only trucks and other big vehicles to pass.
The typhoon drenched Manila overnight but caused no widespread flooding in the sprawling capital of 12 million that floods often because of poor infrastructure and clogged drainage and water canals.
Nari was the 19th storm to enter the country this year. About 20 to 22 tropical storms lash the Philippines yearly during the monsoon season from July to December.
