MANILA (UPDATE) - Storm signal no.1 was raised early Sunday in several areas as tropical storm Maring merged with now-low pressure area Nando, the state weather bureau said.
Maring was last estimated 730 kilometers east of Tuguegarao City, Cagayan at 10 a.m., moving north northwest at 30 km per hour while packing maximum winds of 85 kph and gusts of up to 105 kph, PAGASA said in its 11 a.m. bulletin.
Topical cyclone wind signal no.1, where strong winds are expected within 36 hours, was hoisted over the following areas:
- Cagayan including Babuyan Islands
- Mountain Province
- northern portion of Benguet (Buguias, Bakun, Kibungan, Mankayan)
- Ilocos Norte
- Ilocos Sur
- Eastern Samar
- eastern portion of Northern Samar (San Roque, Pambujan, Las Navas, Catubig, Laoang, Mapanas, Lapinig, Gamay, Palapag, Mondragon, Silvino Lobos)
- eastern portion of Samar (Matuguinao, San Jose de Buan, Hinabangan, Paranas)
- Dinagat Islands
- Surigao del Norte
Moderate to heavy rains due to the tropical storm are expected over Catanduanes, while light to moderate with at times heavy rains are forecast over Bicol Region and Visayas, PAGASA said.
It added that the enhancement of the southwesterlies might bring rains over Western Visayas, Zamboanga Peninsula, Palawan, and Occidental Mindoro.
The tropical storm is forecast to gradually intensify and may be upgraded to severe tropical storm category within the next 24 hours, PAGASA said.
It is expected to move generally westward over the Luzon Strait and pass close or over the Babuyan Islands between
Monday evening and early Tuesday.
"The possibility of a landfall over mainland Luzon is not ruled out at this time," PAGASA said.
The storm is then expected to move generally westward over the West Philippine Sea beginning Tuesday, it added.
