MANILA—Weather system Perla has intensified into a severe tropical storm, the PAGASA said in its 5 p.m. advisory Saturday.
Perla was spotted at 3 p.m. approximately 570 kilometers (km) east northeast of Basco town, Batanes, while packing maximum sustained winds of up to 100 kilometers per hour (kph) with 125 kph gusts while moving northwest at 15 kph.
It could intensify into a typhoon within 24 hours, the state weather bureau said.
Perla, however, is expected to leave the Philippine area of responsibility (PAR) Sunday night the earliest.
Meanwhile, a shallow low-pressure area was spotted 1,835 km east of southern Luzon. It is expected to enter the PAR on Monday or Tuesday, and could develop into a tropical cyclone.
A tropical depression was also sighted 3,235 km east of Mindanao with maximum sustained winds of up to 55 kph and 70 kph gusts while moving west-northwest at 30 kph.
It is expected to turn into a typhoon within 2 to 3 days, and enter the northeastern portion of PAR in the coming days. The weather system, however, is not expected to make landfall.
Occasional gusty conditions will be experienced in extreme northern Luzon until early next week due to the northeast surface wind flow.
Sea travel is risky in seaboards of northern Luzon due to rough sea conditions due to the northeast surface wind flow.
