MANILA, Philippines - The state-run weather bureau on Saturday said the low pressure area earlier spotted is now estimated to be at 680 kilometers east of General Santos City.
The bad weather brought about by the LPA prompted Cebu Pacific Air to cancel six domestic flights, the Philippine News Agency reported.
A northeast monsoon, meantime, is affecting Luzon.
"The regions of CARAGA and Davao will experience cloudy skies with moderate to heavy rainshowers and thunderstorms which may trigger flashfloods and landslides," the Philippine Atmospheric and Astronomical Services Administration said in its latest weather update.
Visayas and the rest of Mindanao, on the other hand, will have cloudy skies with light to moderate rainshowers and thunderstorms.
"Cagayan Valley and the province of Aurora will be cloudy with light rains. Metro Manila and the rest of Luzon will have partly cloudy to cloudy with isolated rainshowers or thunderstorms," PAGASA added.
Moderate to strong winds will prevail over the country and coastal waters will be moderate to rough.
Cancelled flights
The PNA, citing a report of the airport's Media Affairs Division, said the grounded flights were 5J-381/382 Manila-Cagayan de Oro City-Manila, which was supposed to depart at 4:40 a.m. and arrive back to Manila at 8:10 a.m.
Other flights that were called off are: 5J-781/782 and 5J-939/940 both having Manila-Ozamiz-Manila routes.
Also cancelled were Manila-Butuan-Manila flights and Manila-Tagbilaran-Manila flights of Cebu Pacific Air.
