Weather Today – November 6, 2017 – Three weather systems to dampen PH

Different weather systems prevail within the Philippine Area of Responsibility (PAR). The Tail-end of a Cold Front and Northeast Monsoon or Hanging Amihan are now dominant in the Northern Luzon while the Intertropical Convergence Zone (ITCZ) affects the entire Mindanao.

The Tail-end is the extended part of a frontal system, where cold and warm air masses meet. Meanwhile, Hanging Amihan is cold and dry air coming from the Mainland China or Siberia. The ITCZ, on the other hand, is the boundary of winds coming from the Northern and Southern Hemispheres. These weather systems are expected to bring rains in some parts of the archipelago on the last Sunday of November.

Mindanao, Eastern Visayas, Aurora, Cagayan, Isabela, Nueva Vizcaya and Quirino will experience cloudy skies with scattered rain showers and thunderstorms. Isolated light rains will affect Ilocos Region, Cordillera Administrative Region (CAR), Batanes and Babuyan Group of Islands. Metro Manila and the remaining parts of the country can expect generally fair weather apart from the isolated rain showers or thunderstorms mostly in the afternoon or evening.

Several seaboards in country are now placed under the gale warning, where fishing boats and other small sea craft are not allowed to sail due to rough to very rough sea condition. Wave height ranging from 2.8 to 4.5 meters may be experienced in Batanes, Calayan, Babuyan, Cagayan, Isabela, northern and western coast of Ilocos Norte, Aurora, Camarines provinces, eastern coast of Quezon including Polillo Islands, eastern coast of Albay, Catanduanes, eastern Samar and eastern section of Southern Leyte.
