Tropical storm Amang headed north, prompting the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) to place most of Luzon, including Metro Manila, under storm signal no. 1.
The storm also cut the much-awaited visit of Pope Francis to the calamity-hit areas in Leyte island by a few hours on Saturday. It made landfall in Dolores, Eastern Samar yesterday afternoon.
In its latest weather bulletin, Pagasa said that tropical storm Amang was already 60 kilometers north northeast of Borongan City in Eastern Samar with maximum sustained winds of 100 kph near the center and gustiness of up to 130 kph.
The storm is expected to be at the vicinity of Infanta, Quezon late yesterday, and around 155 kilometers east northeast of Aparri, Cagayan by Monday afternoon. The storm is also expected to continue to head north to Batanes islands on Tuesday afternoon.
Pagasa placed the following areas under storm signal no. 2: Catanduanes, Albay, Camarines Sur, Camarines Norte, Southern Quezon, Sorsogon, Masbate, and the islands of Burias, Ticao and Polillo in Luzon; and Northern Samar, Eastern Samar, Samar, and Biliran in the Visayas.
Residents in these areas were advised to prepare for winds of 61-100 kph and for heavy to intense rains, which may cause floods or landslides. Residents in coastal areas are also alerted against possible storm surges of less than two meters.
Storm signal no. 1 was hoisted over Metro Manila, Cavite, Laguna, Rizal, rest of Quezon, Laguna, Batangas, Bulacan, Nueva Ecija, Aurora, Quirino, Isabela, Marinduque, Oriental Mindoro and Romblon in Luzon; and in Leyte, Southern Leyte, extreme Northern Cebu, Bantayan Island and Camotes Island in the Visayas.
These areas will have occasional rains with occasional gusty winds.
The estimated rainfall amount is from 7.5 to 20 millimeters per hour (heavy to intense) within the 400-km diameter of the storm. Ocean waves may reach up to nine meters within its diameter.
Fisherfolks and those with small seacrafts are advised not to venture out over the seaboards of Luzon, the Visayas and the eastern seaboard of Mindanao.
Pagasa also said the public and the disaster risk reduction and management council concerned are advised to take appropriate actions.
