MANILA - (UPDATED) Rains will continue to dampen large swathes of the country on Tuesday even after tropical storm "Isang" leaves the Philippine area of responsibility by midday, state weather bureau PAGASA said.
PAGASA, in a weather bulletin, said Isang was packing top sustained winds of 80 kilometers per hour (kph) near the center and gusts of up to 97 kph. Moving at 20 kph, it was last spotted in the vicinity of Itbayat, Batanes at 3 a.m.
"Kung hindi po magbabago ang bilis niya baka mamayang hapon o tanghali makalabas na rin po ito," PAGASA meteorologist Gener Quitlong told DZMM.
The southwest monsoon or habagat, Quitlong said, will continue to affect Luzon and the Visayas after the tropical storm exits PAR.
The habagat will dump rains that may trigger floods and landslides in Metro Manila, Central Luzon, Mimaropa, Calabarzon, Cordillera, Cagayan Valley and Ilocos region.
Light to moderate and possible occasionally heavy rains meanwhile will prevail in the regions of Bicol, Eastern and Western Visayas, Caraga and Davao.
A yellow rainfall warning remained over Metro Manila at past 9 a.m., said PAGASA forecaster Nikos Peñaranda.
"This means that flooding is still possible in low-lying areas and we are still expecting heavy rains in some portions of Metro Manila within the next couple of hours," Peñaranda said in a phone interview with ANC.
Storm signal no. 2 meanwhile was still hoisted over the Batanes islands. Signal no. 1 was raised over Northern Cagayan, Babuyan islands, Apayo and Ilocos Norte.
"These are mostly mountainous areas so the risk for landslides and flashfloods is still high in these areas," warned Peñaranda.
"In those areas over the Batanes region, we're still expecting waves to reach between 4.1 to 14 meters so that is really treacherous to small fishing and maritime vessels."
