DEKAD NO. 28      OCTOBER 1-10, 2019

Philippine Agri-Weather Forecast

The weather systems that will likely affect the whole country are the trough of tropical cyclone, low pressure area (LPA), easterlies and intertropical convergence zone (ITCZ).

During the start of the dekad, extreme Northern Luzon will be cloudy with rainshowers and thunderstorms while the rest of the archipelago will experience partly cloudy to cloudy skies with isolated rainshowers. Then, the regions of Zamboanga Peninsula, Northern Mindanao, Eastern Visayas, Bicol, and the provinces of Aurora, Quezon, Isabela and Cagayan are expected to have cloudiness with scattered rainshowers and thunderstorms. The remaining areas of the country will have better weather condition except for possible isolated rainshowers. During the middle of the dekad, the LPA will bring cloudy skies with rainshowers and thunderstorms over Cagayan Valley, Cordillera and Ilocos Region while the rest of the archipelago will have partly cloudy to cloudy skies with chances of isolated rainshowers or thunderstorms. Throughout the rest of the forecast period, the whole country is expected to have improved weather condition except for possible isolated rainshowers or thunderstorms mostly in the afternoon or evening.

During the early days of the dekad, winds coming from the northwest to southwest will prevail over the eastern section of Northern Luzon while the remaining areas in Luzon will have winds coming from the southwest. The rest of the country will have winds blowing from the south to southwest. While the LPA approaches the extreme northern part of the country during the middle of the forecast period, gusty winds may be felt over the northern part of Cagayan Valley, Ilocos and Cordillera Region. As the weather disturbance moves away from the archipelago, winds coming from the northeast to east will slowly prevail over Luzon and Visayas while Mindanao will have winds from the south to east.

During the forecast period, the seaboards of Northern Luzon will have moderate to occasionally rough seas while the rest of the archipelago will experience slight to moderate coastal waters.

ENSO-neutral condition is present in the tropical Pacific.
