RAINFALL

Amang could dump from 50 millimeters to 100 mm of rain over the Bicol region from Tuesday to Wednesday night.

It may bring heavy rains over Bicol, the northern and southeastern portions of Quezon, and the eastern portions of Rizal and Laguna from Tuesday night until Friday night.

OUTLOOK

Amang is currently moving westward at 15 kph, and is expected move generally westward or west northwestward in the next 12 to 24 hours.

Its center will move over the the coastal municipalities of Camarines Provinces before turning more northwestward towards the waters east of Quezon, with the possibility of passing near or over the Polillo Islands, PAGASA also added.

Amang may make another landfall over Aurora by Thursday afternoon or evening, and is expected to remain a tropical depression for much of the forecast period.

“It is likely to weaken into a low pressure area by late Thursday due to increasing vertical wind shear, intrusion of dry air, and interaction with the rugged landmass of eastern Luzon,” PAGASA also said.
