The northeast monsoon or “hanging amihan” would continue to prevail in the country until mid-March, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
In an interview, PAGASA weather forecaster Meno Mendoza said the weak northeast monsoon will be the dominant weather system affecting extreme Northern Luzon.
The northeast monsoon is the cold wind from Siberia that blows into the country, usually from mid-October until March.
For Sunday’s weather forecast, he said the northeast monsoon is expected to bring partly cloudy to at times cloudy skies with isolated light rains over the Batanes, Calayan and Babuyan islands while the rest of the country, including Metro Manila, will be partly cloudy to cloudy with isolated rainshowers or thunderstorms.
“As of now, we are in the neutral season when we experience the average temperature. By the second or third week of March until May of this year, we will be experiencing the dry or summer season,” Mendoza told the Philippines News Agency.
He said the state weather bureau will officially declare the onset of the dry or summer season if the “cold” northeast monsoon has ended and the easterlies or warm winds from the Pacific Ocean are in effect.”
He said the termination of the northeast monsoon is the agency’s primary indicator of the onset of summer.
During summer months, Mendoza said the easterlies and the high-pressure area (HPA), which is the opposite of a low pressure area (LPA), will be the dominant weather system in the country.
In its advisory, PAGASA said moderate to strong winds coming from the northeast will prevail over the Visayas and eastern Mindanao and coastal waters along these areas will be moderate to rough.
Elsewhere, winds will be light to moderate blowing from the northeast with slight to moderate seas. PNA
