Despite the already sweltering conditions across the country, the state weather bureau PAGASA warned on Thursday that the peak of the dry season is yet to come.

The prevailing weather system known as Easterlies continues to affect large parts of the country. This system brings warm and humid air from the Pacific Ocean, which is primarily responsible for the elevated temperature and heat index levels currently being recorded in various regions.

According to PAGASA, 28 areas across the country are expected to experience heat index levels classified under the “danger” category, ranging from 42 to 51 degrees Celsius.

Heat index refers to the apparent temperature felt by the human body, which combines actual air temperature and humidity levels.

"Iyong forecast po natin ngayong araw sa Metro Manila, possible po iyong 41 to 42 degrees Celsius. And then kung makikita po natin, ang pinakamataas na posibleng maitala ngayon araw ay 45 degrees Celsius dito po sa may Tuguegarao, Cagayan," said PAGASA weather specialist Chenel Dominguez.

Several provinces are also expected to endure extreme heat, particularly those in the Ilocos Region, Central Luzon, CALABARZON, MIMAROPA, Bicol Region, and Western and Central Visayas.

But according to PAGASA, the current high temperatures could intensify further in the coming days and weeks.

"Sa nakikita po natin, patuloy pa rin tayong makakaranas ng mainit na panahon sa mga susunod na araw, linggo. Possible po umabot din po ito ng May. At hindi pa rin po ito iyong ng peak ng pinaka tag-init. Possible po makakaranas pa rin tayo ng mas mainit na panahon," Dominguez emphasized.

Among those most affected by the oppressive heat are ride-hailing drivers, who spend long hours on the road and are constantly exposed to the sun.

"Ako madalas, kapag talagang sobrang init, ang ginagawa ko, inuuwi ko na lang. Safety na lang din," shared one ride-hailing driver.

"Dapat talaga lagi kang may baong tubig para at least mapawi ang init, iyong pagod. Kailangan talaga hindi ka mauhaw ng matagal. Kasi dapat hydrated ka palagi. Mahirap na atakihin ka bigla," the driver added.

Meanwhile, the intertropical convergence zone is expected to persist but will only affect parts of Mindanao.

PAGASA also noted that there are still no signs of the southwest monsoon or 'habagat' season, which typically signals the start of the rainy season.

The weather bureau continues to advise the public to stay hydrated, wear light-colored clothing, and avoid going outdoors unless necessary.
