High heat index expected in Zambales, Pangasinan

At least five cities in the Philippines might experience a 40°C or higher heat index this Wednesday, 5 March.

Based on the Highest Heat Index Forecast of the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA), the highest heat index expected this Wednesday is 42°C, which is forecasted in Dagupan City, Pangasinan.

Other areas in Luzon that were also forecasted to have dangerous heat index levels are Echague, Isabela, and Sangley Point in Cavite with 40°C.

A 41°C heat index is anticipated over Olongapo City and Iba in Zambales, and Calapan in Oriental Mindoro.

Cotabato City is also forecasted to experience a 41°C heat index.

The heat index determines the temperature at which the human body feels, and it is usually higher than the actual air temperature.

PAGASA weather specialist Benison Estareja said the warm easterlies remain the dominant weather system, bringing humid conditions to most of the country.

Through the PAGASA’s Automatic Weather Station Heat Index on Tuesday, the heat index in Zamboanga City peaked at 46°C — a temperature already at the danger level.

The PAGASA noted that a temperature ranging between 42°C to 51°C can pose a danger to the human body as it could cause heat cramps and heat exhaustion.

“Heat stroke is probable with continued exposure,” the post further added.

In a statement, the Office of the Civil Defense Administrator Undersecretary. Ariel F. Nepomuceno urged the Filipinos to recognize the risks and to remain vigilant to avoid heat-related illnesses.
