MANILA, Philippines — Several parts of the country will continue to experience rainy and unsettled weather as multiple weather systems affect the Philippines, according to the 24-hour public weather forecast issued Monday afternoon, January 5.
The state weather bureau reported that a shear line is influencing the eastern section of Southern Luzon, while the northeast monsoon is affecting most of Luzon. Meanwhile, easterlies continue to bring rain to large portions of the Visayas and Mindanao.
Residents in the Zamboanga Peninsula, Basilan, Tawi-Tawi, and Palawan can expect cloudy skies with scattered rains and thunderstorms caused by the trough of a low-pressure area (LPA). Authorities warned of possible flash floods or landslides in these areas, especially during periods of moderate to heavy rainfall.
Similar weather conditions are expected in the Bicol Region, Quezon, Oriental Mindoro, Marinduque, Romblon, Northern Samar, and parts of Western Visayas including Antique, Aklan, Capiz, and Iloilo. Cloudy skies with scattered rains and isolated thunderstorms may trigger flash floods or landslides due to the continuing effects of the shear line.
The rest of the Visayas and Caraga will also see cloudy skies with scattered rains and thunderstorms brought by easterlies, with weather officials advising residents to stay alert for possible flooding and landslides.
In contrast, the Cordillera Administrative Region, Cagayan Valley, and Aurora will experience cloudy skies with light rains due to the northeast monsoon, with no significant impacts expected. Metro Manila and the rest of Luzon will have partly cloudy to cloudy skies with isolated light rains, also caused by the monsoon.
For the rest of Mindanao, partly cloudy to cloudy skies with isolated rain showers or thunderstorms are forecast, although severe thunderstorms could still lead to localized flash floods or landslides.
Coastal conditions remain risky in several areas. Luzon and the eastern sections of the Visayas and Mindanao will experience moderate to strong winds blowing from the northeast to north, resulting in moderate to rough seas with wave heights ranging from 1.8 to 4.0 meters. The rest of the country will see light to moderate winds and slight to moderate seas.
For the past 24 hours ending at 4:00 p.m., temperatures ranged from a low of 22.4°C recorded at 6:30 a.m. to a high of 29.0°C at 2:00 p.m. Relative humidity dipped to 61 percent late in the morning and peaked at 83 percent in the early hours of the day.
Astronomical data for Metro Manila shows sunrise at 6:23 a.m. tomorrow and sunset today at 5:40 p.m. The moon will rise at 8:39 p.m. tomorrow and set at 8:45 a.m., with the moon about 87 percent illuminated.
Weather officials continue to advise the public, especially those in flood- and landslide-prone areas and coastal communities, to stay updated on the latest advisories and take necessary precautions.
