MANILA — Several weather systems continue to affect the country on Tuesday, January 13, with rains expected over parts of Northern Luzon and southern Mindanao, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
PAGASA said a shear line is affecting the eastern section of Northern Luzon, bringing cloudy skies with scattered rains and isolated thunderstorms over Cagayan, Isabela, and Aurora. Moderate to at times heavy rainfall in these areas may trigger flash floods or landslides, especially in low-lying and mountainous communities.
Meanwhile, the Northeast Monsoon or amihan continues to influence the rest of Northern Luzon. The Cordillera Administrative Region and the remaining parts of Cagayan Valley are expected to experience cloudy skies with light rains, while the Ilocos Region and the rest of Central Luzon may have partly cloudy to cloudy skies with isolated light rains. No significant weather-related impacts are expected in these areas.
In southern Mindanao, the Intertropical Convergence Zone (ITCZ) is affecting the Davao Region, where cloudy skies with scattered rains and thunderstorms are forecast. PAGASA warned of possible flash floods or landslides due to moderate to occasionally heavy rainfall.
Metro Manila and the rest of the country will experience partly cloudy to cloudy skies with isolated rainshowers or thunderstorms caused by easterlies. Localized flooding or landslides may occur during severe thunderstorms, PAGASA added.
Strong to moderate northeasterly winds are expected over Northern Luzon, the eastern section of Central Luzon, Southern Luzon, and the Visayas, resulting in moderate to rough coastal waters with wave heights ranging from 2.1 to 3.5 meters. Similar conditions are forecast over the eastern section of Mindanao, with waves reaching up to 3.1 meters.
Elsewhere, winds will be light to moderate with slight to moderate seas, with wave heights of 0.6 to 2.1 meters.
PAGASA also reported that the maximum temperature recorded at its Science Garden station in Quezon City over the past 24 hours reached 30.2 degrees Celsius at 2 p.m., while the minimum temperature dipped to 23.2 degrees Celsius at 6 a.m. Relative humidity peaked at 93 percent early Tuesday morning.
Residents in affected areas were advised to remain alert for weather updates and possible advisories, especially those in flood- and landslide-prone locations.
