Two prevailing weather systems, the shear line and the northeast monsoon (amihan), will continue to trigger rainfall across several regions of the Philippines, the state weather bureau reported Sunday.
In its 4:00 a.m. bulletin, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) issued warnings for heavy rains over the Dinagat Islands, Surigao del Norte, Surigao del Sur, Agusan del Norte, Agusan del Sur, Davao Oriental, and Davao de Oro.
Residents in Soccsksargen, Eastern Samar, Leyte, Southern Leyte, Camiguin, Misamis Oriental, and Bukidnon should expect cloudy skies with scattered rain showers and isolated thunderstorms.
PAGASA also warned that moderate to heavy rainfall in these areas could lead to flash floods or landslides.
Meanwhile, the northeast monsoon is affecting Luzon and parts of the Visayas. Cooler weather with light rains is expected in Cagayan Valley, the Bicol Region, Apayao, Kalinga, Mountain Province, Ifugao, Aurora, Quezon, and the rest of the Visayas and Northern Mindanao.
Metro Manila and the remaining parts of the country will experience partly cloudy to cloudy skies with isolated rains due to the monsoon.
Forecasters are also tracking a low pressure area (LPA) located 765 kilometers east of General Santos City. According to PAGASA, the system is unlikely to redevelop into a tropical depression within the next 24 hours.
Strong to gale-force winds are expected over the eastern section of Mindanao, bringing rough to very rough sea conditions.
The rest of the archipelago will experience moderate to strong winds and moderate to rough coastal waters. Mariners are advised to take necessary precautions.
