According to PAGASA Weather Forecaster Samuel Duran, no other weather disturbance is expected to enter or develop within the Philippine Area of Responsibility (PAR) within the next 2-3 days. However, three rain-inducing weather systems prevail including the Tail-end of a Cold Front, Trough of Low Pressure Area (LPA) and Northeast Monsoon.
The Tail-end of a Cold Front is the boundary of two different air masses, where the cold air mass dominates the warm air mass. When winds converge, convective clouds are formed, bringing rains in affected areas. In the next hours, cloudy skies with scattered rain showers and thunderstorms will prevail in the provinces of Cagayan, Isabela, Aurora and Quezon.
The same weather condition is expected in Mindanao due to the trough or extended part of an LPA. Meanwhile, Hanging Amihan will continue to bring isolated light rains in Batanes and the Babuyan Group of Islands. Metro Manila and the rest of the country will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms mostly in the afternoon or evening.
Sea travelers and fisherfolk are not advised to venture out into the northern seaboard of Northern Luzon, where gale warning remains hoisted. Batanes, Calayan, Babuyan, coasts of Cagayan and Ilocos Norte will have rough to very rough sea conditions with wave height ranging 3.1 to 4.5 meters.
Apart from the light rains and bumpy coastal waters, Amihan is also responsible for the slight drop in temperatures, mostly in the northern parts of Luzon. Here are the lowest temperatures recorded yesterday, November 20, 2017.
Baguio City – 17.0°C
Itabayat and Basco, Batanes – 21.0°C
Tanay, Rizal – 21.3°C
