10 - Day Regional Agri-Weather Information

DEKAD NO. DEKAD NO. 34 DECEMBER 1 – 10, 2019

Philippine Agri-Weather Forecast

The weather systems that will likely to affect the whole country are the northeast monsoon, tropical cyclone and tail-end of a cold front.

During the early days of the dekad, Typhoon “Tisoy” will bring stormy weather over Metro Manila, Visayas and the regions of Bicol, CALABARZON and MIMAROPA while Central Luzon, Surigao del Norte, and the southern portions of Ilocos Region, Cordillera and Cagayan Valley will experience cloudy skies with rains and gusty winds. Northern Mindanao and the rest of Luzon will be cloudy with scattered rainshowers and thunderstorms. Improved weather condition is expected over the rest of Mindanao. After this, as the tropical cyclone moves away from the landmass, gradual improvement of weather is expected over the areas affected by Typhoon “Tisoy”. However, Northern Luzon will continue to have cloudiness with scattered rainshowers and thunderstorms while the rest of the archipelago will experience better weather condition except for some chances of isolated rainshowers. During the mid of the second half, Bicol Region, Visayas and Mindanao will have cloudy skies with rainshowers and thunderstorms. Northern Luzon and the provinces of Aurora and Quezon will be cloudy with light rains while the rest of Luzon will experience partly cloudy to cloudy skies with isolated rainshowers.

During the early days of the dekad, winds coming from northeast will be experienced in northern and central sections of Luzon while winds coming from the northeast to northwest will blow over the rest of the country. Metro Manila and the regions of Bicol, CALABARZON, Central Luzon and Eastern Visayas, and the provinces of Oriental Mindoro, Occidental Mindoro, Romblon, Marinduque, and the northern portions of Palawan, Central Visayas and Western Visayas are expected to experience gusty winds. Afterwards, winds from northeast to east will blow over the northern and eastern sections of Luzon while the rest of the country will have winds coming from the east to northeast. During the start of the second half, northeasterly windflow will progress over Luzon while the rest of the country will have winds coming from east to northeast.
During the early days of the dekad, rough to very rough seas are expected to occur over Luzon and eastern seaboards of Visayas while the rest of the country will have moderate to rough seas. As Typhoon “Tisoy” moves away from the country, during the mid of the forecast period, rough to very rough seas will continually prevail over the northern, western and the central sections of Luzon. The coastal waters of Visayas, Mindanao and the rest of Luzon will have moderate to rough seas. However, the eastern seaboards of Southern Luzon may start to experience rough to very rough seas at the middle of the second half of the dekad up to the end of the forecast period.

ENSO-neutral condition will likely to continue throughout the forecast period.

Farm Advisories

The frequency of tropical disturbances causes wet weather condition which promotes fungal development and damage stored farm products. It can also reduce the quality, viability and market price of the grains. Thus, it is advised to keep barns and crop storage rooms in good, dry, well ventilated condition. Big trees may have weak/dead branches that can fall and cause damages to houses, animal shelters and hurt inhabitants during strong winds and continuous heavy rains. As precautionary measure, cutting of excess leaves and branches of big trees is advised. Also, pruning of banana leaves that will likely be broken can be saved from total destruction. Continuous rain causes soil erosion and landslide which may require covercropping, land terracing and waterway declogging activities.
