Meanwhile, PAGASA said that most parts of the country are under the “extreme caution” classification, with temperatures ranging from 33°C to 41°C.
The heat index is the human discomfort index that gives the "apparent" temperature, or what humans perceive or feel as the temperature affecting their body.
The effect-based danger classification ranges from 42°C to 51°C, and its effects on the body are that heat cramps and exhaustion are likely, and heat stroke is probable with continued exposure.
Symptoms of heat-related illnesses include sweating heavily, exhaustion or fatigue, dizziness, blacking out, weak but fast pulse, nausea, and vomiting.
PAGASA last March 22 declared the start of the warm and dry season in the country.
