Ten-Day Regional Agri-Weather Information

DECADE NO. 2  JANUARY 11- 20, 2017

PHILIPPINE AGRI-WEATHER FORECAST

The weather systems that will affect the whole country are northeast monsoon, LPA (previously Tropical Depression Auring) and tropical cyclone.

During the early days of the ten-day forecast, Northern Luzon will experience light rains while the cloudiness associated with the LPA will continue to bring rains and thunderstorms over Visayas, CALABARZON, and the regions of Bicol and MIMAROPA. Gradual improvement of weather over these areas is expected afterwards. As the LPA (formerly TD Auring) moves outside the Philippine Area of Resposibility (PAR), another LPA at the east of the country is predicted to enter PAR. This LPA may develop into a tropical cyclone at the midst of the forecast period but will not have direct effect in the country. It will move in a north northwest direction before going in a north northeast track. Light rains are expected over the eastern section of Luzon and Visayas as the northeasterly wind flow start to strengthen again.  Southern Luzon and Visayas are expected to have rains with thunderstorms at the midst of the forecast period while the rest of Luzon will have light rains. The rest of the country will have good weather. During the last part of the decade, partly cloudy to cloudy skies with isolated thunderstorms will prevail over the whole archipelago.

Gradual decrease of temperature is expected over Northern and Central Luzon at the midst of the forecast period. This condition will continue throughout the remaining days of the decade.

Moderate to strong winds will prevail over Luzon while light to moderate winds will blow over Mindanao throughout the decade. During the first half of the forecast period, Visayas will have light to moderate winds. Visayas will have moderate to strong winds during the remaining days of the ten-day period.

Visayas and Mindanao will have slight to moderate seas during the first half of the decade. Afterwards, the coastal waters over Visayas will be moderate to rough while Mindanao will have slight to moderate seas. The seaboards over Luzon will be moderate to rough throughout the ten-day period.

The eastern and central equatorial Pacific is in neutral condition.
