DEKAD NO. 28 1 – 10 OCTOBER 2020
Philippine Agri-Weather Forecast
The weather systems that will likely affect the whole country are the southwest monsoon (SW), low pressure area (LPA), tail-end of a cold front, tropical cyclone and localized thunderstorms.
During the early days of the dekad, cloudy skies with scattered rainshowers and thunderstorms will be experienced over Metro Manila, CALABARZON, MIMAROPA, Bicol Region and Eastern Visayas due to the trough of LPA while the rest of the country will have partly cloudy to cloudy skies with isolated rainshowers. After this, another LPA may develop over the eastern section of Southern Luzon and bring cloudiness with rainshowers and thunderstorms over Metro Manila, Southern Luzon and Visayas. The remaining areas of the archipelago will experience good weather except for some chances of isolated rainshowers. During the second half of the dekad, Cagayan Valley, Metro Manila, Southern Luzon, Visayas, Zamboanga Peninsula and the province of Aurora will gradually experience cloudy skies with rainshowers and thunderstorms. However, the cloudiness may progress during the latter part of the forecast period, bringing rainshowers and thunderstorms over most areas in Luzon and Visayas. The rest of the country will experience partly cloudy to cloudy skies with possible occurrences of isolated rainshowers.
During the first half of the dekad, winds coming from the northeast will prevail over extreme Northern Luzon while Central Luzon and the rest of Northern Luzon will have winds from the northeast to northwest. The remaining areas of the country will have winds from the southwest to west. As the northeasterly winds continue to blow over extreme Northern Luzon, winds from the northeast to east will gradually prevail over Central Luzon, Metro Manila, CALABARZON, rest of Northern Luzon and the provinces of Mindoro, Marinduque and Romblon during the second half of the dekad. Visayas and Palawan will experience winds coming from the southwest to southeast while Mindanao will have winds from the southwest. During the latter part of the forecast period, the extreme portion of Northern Luzon will have winds from the northeast to east while Visayas and the rest of Luzon will have winds from the southwest to southeast. The rest of the archipelago will have winds from the southwest to west.
During the early days of the forecast period, the coastal waters over Northern Luzon will be moderate to rough while the rest of the archipelago will have slight to moderate seas. After this, the seaboards of the whole country will be slight to moderate. The coastal waters over Northern Luzon will gradually become moderate to rough during the second half of the forecast period. This condition will progress over the coasts of Central Luzon.
Weak to moderate La Niña is likely to persist across the tropical Pacific until the first quarter of 2021.
