MANILA, Philippines — A total of 34 areas across the country registered “dangerous” peak heat indices or above 42ºC (degrees Celsius), said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa) on Tuesday.

According to Pagasa, heat index refers to the “measure of the contribution that high humidity makes with abnormally high temperatures in reducing the body’s ability to cool itself.”

A heat index ranging from  42ºC to 51ºC is considered part of the “danger category.”

Once it reaches this point, the risk for various heat-related illnesses such as heat cramps, heat exhaustion, and even heat stroke during continued exposure increases.

Based on Pagasa’s latest computed heat index, Maasin, Southern Leyte registered the highest peak heat index on Tuesday at 49ºC.

In Metro Manila, Ninoy Aquino International Airport (Naia) in Pasay City logged a peak heat index of 43ºC.
