MANILA, Philippines -- Typhoon "Huaning" has slightly intensified as it continues to move in a west northwest direction, state weather bureau PAGASA said Thursday morning.
PAGASA said the typhoon has gained strength and is now packing maximum sustained winds of 185 kilometers per hour (kph) near the center and gustiness of up to 220 kph.
It was spotted 810 kilometers east northeast of Itbayat, Batanes as of 10 a.m.
Huaning was still moving west northwest at 20 kph.
Public storm warning signal number 1 remains hoisted over the Batanes Group of Islands.
The typhoon is expected to bring estimated rainfall amount of 10 to 46 millimeters per hour (heavy to torrential) within its 800-kilometer diameter.
PAGASA said Huaning is expected to be outside the Philippine Area of Responsibility (PAR) by Saturday morning.
Fishermen, especially those using small sea crafts, are advised not to venture out into the northern and eastern seaboards of Luzon due to big waves generated by the typhoon, PAGASA said.
The regions of Cordillera, Western Visayas, Zamboanga Peninsula, Northern Mindanao and Caraga, and the provinces of Nueva Vizcaya, Quirino, Nueva Ecija, Mindoro, Marinduque and Romblon will experience cloudy skies with light to moderate rains and thunderstorms.
Metro Manila and the rest of the country, meanwhile, will have partly cloudy to cloudy skies with isolated rains or thunderstorms.
