The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said on Tuesday, Jan. 28, that several areas in Luzon, including Metro Manila, will experience cooler weather as the effects of the northeast monsoon, or "amihan," prevail in the coming days.
“Medyo may kalamigan po ang ating mga temperatura dahil inaasahan natin na lalakas ulit yung epekto nitong northeast monsoon (The temperatures are somewhat cooler as we expect the effects of the northeast monsoon to strengthen again),” weather specialist Rhea Torres said in PAGASA’s forecast.
For Jan. 28, Torres noted that temperatures in the Luzon area would range from 14 to 31 degrees Celsius (°C).
The temperatures for some key cities are: Metro Manila (22 to 31 °C), Laoag (22 to 28 °C), Tuguegarao (20 to 28 °C), Baguio (14 to 21 °C), Legazpi (24 to 30 °C), and Tagaytay (19 to 27 °C).
Torres noted that “generally fair weather conditions” are expected in Luzon, except in some areas where isolated and moderate rains are possible.
Effects of weather systems
Meanwhile, Torres mentioned that scattered rainshowers are expected in the rest of the country due to the “amihan,” shear line, and easterlies.
“Sa kasalukuyan, inaasahan pa rin yung mga pag-ulan sa ilang bahagi ng ating bansa dulot ng patuloy na epekto ng mga weather systems na patuloy na nakaka-apekto sa ating kapuluan (Currently, rain is still expected in some parts of our country due to the ongoing effects of weather systems that continue to impact our archipelago),” Torres said.
The shear line, a weather system formed by the collision of warm and cold air masses, is expected to bring rain to several parts of the country.
Torres said light to moderate rains are expected in most parts of the country in the coming days as the effects of the “amihan” continue to prevail. Meanwhile, the impact of the shear line is expected to decrease in the days ahead.
In its weather forecast, PAGASA said the shear line will greatly affect Palawan and the Visayas, while the northeast monsoon will continue to influence weather conditions in the rest of Luzon.
Partly cloudy to cloudy skies with isolated light rains are expected in Metro Manila and the rest of Luzon due to the “amihan.”
The northeast monsoon will bring cloudy skies with rains in Batanes, Cagayan, and Isabela.
Cloudy skies with scattered rains and isolated thunderstorms are expected in the Visayas, Palawan, and Dinagat Islands due to the shear line.
The easterlies will bring cloudy skies with scattered rains and thunderstorms in the rest of Mindanao.
PAGASA warned of possible flash floods or landslides due to moderate to at times heavy rains.
