The warm and dry season just officially started last March 26 but some areas in the country are already experiencing “dangerous” heat index level.

On Wednesday afternoon, March 31, heat index at the Ninoy Aquino International Airport station in Pasay City and Ambulong station in Batangas both reached 41 degrees Celsius–considered to be at “dangerous” level according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

The 41 degrees Celcius heat index was recorded in Ambulong around 2 p.m. and in NAIA at 3 p.m.

PAGASA defines heat index as a human discomfort index that gives the “apparent” temperature or what human perceive or feel as the temperature is affecting their body.

Full exposure to sunshine can increase the heat index by 8 degrees Celsius.

Under a “dangerous” heat index level between 41 degrees Celsius and 54 degrees Celsius, PAGASA said heat cramps and heat exhaustion are likely, while heat stroke is probable with continued activity.

Based on its weather forecast in the next 24 hours, PAGASA said Luzon will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to the prevalence of the warm and humid easterlies.

Meanwhile, PAGASA continues to monitor a low pressure area (LPA) located 135 kilometers east of General Santos City on Wednesday afternoon.

Cloudy skies with scattered rain showers and thunderstorms may prevail across Visayas and Mindanao.
