PAGASA forecast “danger” heat index in at least three areas in the country

The state weather bureau’s heat index forecast, the heat index expected to be computed at the following synoptic stations will be within the “danger” range of 42 to 51 degrees Celsius on Monday:

Science Garden Quezon City – 46°C

Clark Airport, Pampanga – 46°C

CLSU Muñoz, Nueva Ecija – 45°C

The heat index is the measure of the temperature that a person feels in contrast to the actual air temperature.

Computed by factoring in the humidity as well as the air temperature, the heat index measures “human discomfort” and is the “apparent temperature” felt by the human body.

PAGASA’s heat index classification defines heat index temperatures ranging from 42°C to 51°C as being in the “danger” level, where “heat cramps and heat exhaustion are likely; heat stroke is probable with continued exposure.”

Caloocan City, Malabon and Valenzuela has announced that classes in public schools from kindergarten to high school will shift to online or asynchronous classes on Monday due to the heat index.
