Six villages in Olongapo City in Zambales province were submerged in floodwaters due to heavy rains on Monday, a local official said Tuesday.
Olongapo City Mayor Bong Gordon said some houses were submerged in neck-deep floods, forcing residents to stay on their home's roofs.
Gordon said rescue operations have been launched by teams from the Subic Bay Metropolitan Authority for the trapped villagers. He said at least 70,000 residents were affected by the floods.
The mayor said he has ordered the suspension of classes in all levels in the city. He added that some affected residents have been brought to the Olongapo City National High School, which has been turned into an evacuation center.
Weather bureau PAGASA said provinces in Luzon and Visayas will continue to experience monsoon rains. It warned residents against possible flashfloods and landslides.
It also warned small sea crafts against rough seas in Luzon and Visayas due to the southwest monsoon. With a report from Doland Castro, ABS-CBN News
