MANILA, Philippines — The state weather bureau’s station in Pasay City is forecast to have a “danger-level” heat index Friday, May 16, after reporting the same condition for four days straight.
The Ninoy Aquino International Airport station in Pasay City is bracing for a 42° heat index temperature, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa).
On the other hand, Pagasa’s station in Quezon City Science Garden is expected to have 39°C or under the “extreme caution” category.
Also, Pagasa said the danger-level heat index of 42° is seen in the Pagasa stations in these areas nationwide:
42°
Sinait, Ilocos Sur
Batac, Ilocos Norte
Baler, Aurora
Casiguran, Aurora
Iba, Zambales
Subic Bay, Olongapo City
Camiling, Tarlac
Tanauan, Batangas
Coron, Palawan
Cuyo, Palawan
Daet, Camarines Norte
Iloilo City, Iloilo
Dumangas, Iloilo
Butuan City, Agusan del Norte

Dagupan City, Pangasinan
Tugegarao City, Cagayan
44 degrees Celsius
Bacnotan, La Union
Aparri, Cagayan
Sangley Point, Cavite City
Infanta, Quezon
San Jose, Occidental Mindoro
Ranging from 42° to 51°C, the heat index under the “danger” category could likely cause heat cramps and heat exhaustion, while heat stroke is probable with continued exposure to the sun.
Behind the danger category are “extreme caution” ranging from 33 to 41°C and “caution” at 27 to 32°C.
“Extreme danger,” or the highest category of heat index level, is declared when the heat index temperature reaches 52°C and beyond.
Heat index measures the level of discomfort an average person experiences due to the combined effects of the temperature and air humidity.
On March 26, Pagasa announced the start of the dry season in the country. /das/abc
