46ºC heat index logged in Guiuan, Eastern Samar

MANILA, Philippines — The state weather bureau recorded a dangerous heat index of 46ºC (degrees Celsius) in Guiuan, Eastern Samar on Tuesday.

 According to the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa), heat index is “a measure of the contribution that high humidity makes with abnormally high temperatures in reducing the body’s ability to cool itself.”

Pagasa said that a heat index of from 42ºC to 51ºC is under the “danger category,” and warned that it causes heat cramps, heat exhaustion, and even heat stroke with continued exposure.

Two other areas reached “danger” level heat index on Friday – Catarman, Northern Samar and Cotabato City at 42ºC.

Catarman has consistently logged dangerous level heat indexes since March 29.

Pagasa reminded the public that in times of emergency amid intense heat:

• elevated. 
• If conscious, have them sip cool water.
