Manila: Three prevailing weather systems will continue to bring rains and thunderstorms over parts of the country, the weather bureau said Sunday. In its 4 a.m. advisory, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported that the northeast monsoon, locally known as amihan, will result in cloudy skies with light rains over Metro Manila, Cordillera Administrative Region, the rest of Cagayan Valley, Nueva Ecija, Bulacan, and Calabarzon, excluding Quezon.

According to Philippines News Agency, Ilocos Region and the rest of Central Luzon will experience partly cloudy to cloudy skies with isolated light rains due to the influence of the amihan. Meanwhile, Quezon province, along with Cagayan, Isabela, and Aurora, is expected to have cloudy skies with scattered rains and isolated thunderstorms caused by the shear line.

The Bicol Region, Eastern Visayas, Dinagat Islands, Surigao del Norte, and Surigao del Sur will see cloudy skies with scattered rains and thunderstorms as a result of easterlies. The rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms, also influenced by easterlies.

Northern Luzon and the eastern section of Central Luzon will experience moderate to rough coastal waters due to moderate to strong northeast winds. The rest of Luzon and eastern sections of Visayas and Mindanao will also encounter moderate to strong winds and moderate to rough seas because of east to northeast winds. Other regions of the country will have light to moderate northeast to north winds and slight to moderate coastal waters.

No low-pressure area is currently being monitored inside or outside the Philippine Area of Responsibility based on satellite images observed by PAGASA. However, weather forecaster Obit Badrina indicated that a potential low-pressure area might develop between Wednesday and Friday this week, which could bring scattered rains over the eastern section of Visayas and Mindanao, including the Bicol Region.
