Severe tropical storm Fabian continues to move slowly west- northwestward and is expected to bring rains in some parts of Luzon, the state weather bureau said Tuesday.
The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said Fabian was located 1,035 kilometers east- northeast of extreme northern Luzon as of 4 a.m.
It has maximum sustained winds of 95 kilometers per hour near the center and gustiness of up to 115 kph.
"Fabian is unlikely to bring heavy rainfall in the country throughout the forecast period," PAG-ASA said in its latest weather bulletin update.
However, monsoon rains will be experienced in the next 24 hours over Ilocos Region, Cordillera Administrative Region, Cagayan Valley, Zambales, Bataan, Occidental Mindoro, and Palawan, the state weather bureau said.
Based on the latest forecast scenario, there is "an increasing likelihood that Tropical Cyclone Wind Signal No. 1 may be hoisted over Batanes and Babuyan Islands," the PAGASA said.
"Residents and disaster managers in Batanes and Babuyan Islands are advised to continuously monitor the tropical cyclone bulletins," it added.
Rough to very rough seas may be experienced over the seaboards of Batanes and Babuyan Islands, and the western seaboard of Palawan (including Kalayaan and Calamian Islands) and Occidental Mindoro (including Lubang Islands), said PAG-ASA.
"Sea travel is risky for small seacrafts over these waters. Mariners without the proper experience should immediately seek safe harbor," it said.
Fabian is projected to reach Typhoon category tonight or morning of July 21, Wednesday.
"Fabian is forecast to further intensify and reach typhoon category tonight or tomorrow early morning. The tropical cyclone may reach its peak intensity of 150 km/h on Thursday," PAG-ASA said.
It is expected to exit the Philippine Area of Responsibility (PAR) by July 23, Friday, the state weather bureau added.
