A low pressure area (LPA) was spotted in Zamboanga del Sur, causing moderate to occasionally heavy rains and thunderstorms in some provinces in Visayas and Mindanao, the Philippine Atmospheric Geophysical Astronomical Services and Administration (Pagasa) said on Tuesday, January 17.
At 4 a.m., Pagasa said the LPA was 70 kilometers east northeast of Zamboanga City. Heavy rains were pouring in the areas of Eastern Visayas, Caraga, Northern Mindanao, Zamboanga Peninsula and Bohol.
Pagasa added, it may cause possible flashfloods and landslides.
Meanwhile, the tail-end of a cold front is affecting the Visayas.
A tail-end of a cold front is the boundary where the two air mass of different temperature collide causing rains and thunderstorms.
The rest of Visayas and Mindanao will experience cloudy skies with light to moderate rains and isolated thunderstorms.
Provinces that will have cloudy skies with light rains: were Cagayan Valley, Mimaropa (Marinduque, Mindoro Occidental, Mindoro Oriental, Palawan, Puerto Princesa, Romblon), Bicol, Aurora, Quezon.
The partly cloudy to cloudy skies with isolated light rains will prevail over Metro Manila and the rest of Luzon.
Moderate to strong winds blowing from the northeast will prevail over Luzon, Visayas and Caraga (Agusan del Norte, Agusan del Sur, Surigao del Norte, Surigao del Sur and Dinagat Islands). The coastal waters over these areas will be moderate to rough, Pagasa added.
