The Ridge of High Pressure Area remains to be the dominant weather system, bringing higher temperatures in the Philippines today.
It will continue to bring partly cloudy to cloudy skies or fair weather over Luzon, Visayas and Mindanao. However, localized thunderstorms are still expected to form in the afternoon or evening.
You can expect the same weather scenario this weekend, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).
Today, Metro Manila’s heat index may reach up to 40.2 degrees Centigrade, the agency added. Everyone is advised to take precautions.
WHEN WILL TAG-INIT END?
State Meteorologist Buddy Javier states that the Hot and Dry season may last until mid-June. By then, the winds will start to shift and usher in more rains.
But in order to fully establish the end of Tag-init, PAGASA has certain criteria in determining the onset of rainy season in the country, particularly in areas under the Type 1 climate, which produces two pronounced seasons:
1. Dry – October to March
2. Wet – April to September
In order for the agency to officially declare the onset of the rainy season, the following conditions must be present:
1. A total rainfall amount of 25 millimeters or more in a five-day period or at least 1 millimeter of rainfall per day in three consecutive days.
2. Criterion #1 must be met in at least five of the following climate Type 1 stations:
* San Jose, Mindoro
* Metro Manila
In order for Metro Manila to be counted, at least 2 out of 3 Metro Manila stations (Science Garden, Port Area, Sangley Point) must have met the first condition.
