MANILA — Tropical depression Marilyn has entered the Philippine area of responsibility, threatening to dump moderate to heavy rains over vast swaths of Luzon and Visayas, the state weather bureau said Friday. The trough or extension of Marilyn, which entered PAR at 9:30 a.m., may spawn floods and landslides in Visayas, Calabarzon, Bicol, Mimaropa and Zamboanga regions, and Aurora, Quirino, Isabela, and Cagayan provinces, said PAGASA. Metro Manila and the rest of the country will experience localized thunderstorms, added the agency. Marilyn, the country’s 13th storm this year, was 1,645 kilometers east of Central Luzon at 3 a.m., packing maximum sustained winds of 55 kilometers per hour and 70 kph gusts, PAGASA earlier said. The storm and the habagat or southwest monsoon will continue stirring rains over large parts of the country until the weekend, PAGASA weather forecaster Benison Estareja told radio DZMM.
