The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) officially declared on Wednesday the start of the dry season.
“The recent analyses indicate retreat of the high pressure area (HPA) over Siberia, thereby weakening of the associated northeasterly winds and decreasing sea level pressure in the country. Moreover, the wind pattern has generally shifted from northeasterlies to easterlies over most parts of the country as a result of the advancing HPA over the northwestern Pacific,” it said.
These signify the start of the dry season and warmer conditions, according to PAGASA.
With the easterlies as the prevailing weather system, the country could expect warm and humid weather, especially until noon, PAGASA forecaster Ana Clauren said earlier.
Clauren added that rains and thunderstorms may be experienced for a short period in the afternoon or evening.
PAGASA said the day-to-day rainfall across the country will be mostly due to the easterlies and localized thunderstorms.
The weather bureau, meanwhile, urged the public to take precautionary measures to minimize heat stress, and to optimize the daily use of water for personal and domestic consumption.
The Philippines experiences two seasons — the dry season when rain showers are greatly reduced and when the public could expect higher temperatures; and wet season, which usually begins in June.
