MANILA, Philippines – Storm warning signal number 1 has been hoisted over four areas as typhoon "Lawin" moves closer to northern Luzon, the state weather bureau said.

Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) has raised storm warning signal number 1 over Isabela, Cagayan, Calayan Group of Islands and Babuyan Group of Islands.

As of 4 a.m., Lawin was located 585 kilometers east of Baler, Aurora.

The typhoon further intensified, now packing 195 kilometers per hour (kph) near the center and gustiness of up to 230 kph. It was moving north-northwest at 11 kph.

Speaking to radio dzMM, PAGASA forecaster Manny Mendoza said a high pressure area over China is preventing the typhoon from moving northward.

He said the typhoon may move in a west-northwest direction due to the high pressure area.

PAGASA said due to Lawin, Isabela and Cagayan will have rains and gusty winds. MIMAROPA, Bicol region and Visayas will experience cloudy skies with occasional moderate to heavy rains which may trigger flashfloods and landslides.

Metro Manila, CALABARZON, Mindanao and the rest of Luzon will have occasional light to moderate rains and thunderstorms.

Estimated rainfall amount is 10 - 20 millimeters per hour (heavy - intense) within the typhoon's 800-km diameter.

PAGASA also warned fishing boats and other small sea crafts against venturing out into the northern and eastern seaboards of Luzon and the seaboards of Visayas and Mindanao due to big waves generated by the typhoon.
