WEATHER UPDATE — According to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA), three weather systems are affecting the Philippines, such as the Northeast Monsoon (Amihan), shear line, and trough or extension of the Low-Pressure Area (LPA).
The Northeast Monsoon is currently bringing rain to the northern part of Luzon and also reaches the islands of Palawan. Meanwhile, the shear line affects the Bicol Region, Eastern Visayas, Central Visayas, parts of CARAGA, and the Davao Region. Lastly, the trough or extension of the LPA outside the Philippine Area of Responsibility (PAR) brings rain, mainly in the CARAGA and Davao areas.
Based on the weather agency’s latest data, the LPA spotted outside the PAR in the southern part of Mindanao still has a low chance of becoming a Typhoon because of its large and broad circulation.
PAGASA also reports isolated rain showers possible in NCR, including Metro Manila and Western Visayas.
