Meanwhile, the strengthening surge of the Northeast Monsoon (Amihan) will bring cloudy skies with scattered rains over Cagayan Valley and Aurora, and partly cloudy to cloudy skies with isolated light rains over Metro Manila, Ilocos Region, Cordillera Administrative Region (CAR), and the rest of Central Luzon. The rest of the country will have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms.
By Monday (December 15): the Shear Line will continue to bring cloudy skies with scattered rains and isolated thunderstorms Over Bicol Region, Eastern Visayas, Cagayan, Isabela, Quirino, Aurora, and Quezon. Cloudy skies with scattered rains will still prevail over CAR and the rest of Cagayan Valley while the rest of Luzon will experience partly cloudy to cloudy skies with isolated light rains caused by Amihan. Mindanao and the rest of Visayas will have partly cloudy to cloudy skies apart from localized rainshowers or thunderstorms.

Farm Advisory
AREAS AFFECTED BY THE WEATHER SYSTEMS
NORTHEAST MONSOON, SHEAR LINE, THUNDERSTORMS AND MODERATE TO HEAVY RAINS
- Construct or repair drainage canals, dikes, and contour bunds before continuous rainfall.
- For upland farms, install contour hedgerows or barriers to reduce soil erosion.
- Use raised beds for vegetables to prevent waterlogging.
- For lowland rice, ensure paddies have good drainage and are protected from flood overflow.
- Delay fertilizer application until after heavy rainfall to reduce nutrient loss through leaching.
- Conduct regular field monitoring for pests and fungal diseases that thrive in wet conditions (e.g., rice blast, bacterial blight, leaf spot, and fruit rot).
- Use biocontrols or recommended fungicides when early symptoms appear.
ENSO ALERT SYSTEM STATUS
(updated: 04 December 2025)
https://www.pagasa.dost.gov.ph/climate/el-nino-la-nina/monitoring
Farmers are advised to harvest mature crops early to avoid losses from persistent La Niña rains. Reinforce storage areas and drying facilities to protect produce from heavy rainfall and strong winds. Maintain good drainage in the farm areas to prevent flooding and damage. Increase monitoring for pests and diseases that thrive in wet conditions. Regularly monitor weather reports and advisories from PAGASA and Department of Agriculture and implement soil conservation practices.
