PAGASA said the "danger" category of heat index is between 42ºC to 51ºC.

With these temperatures, heat cramps and heat exhaustion are likely, while heat stroke is probable with continued exposure, the weather bureau said.

The heat index is the measure of the temperature that a person feels in contrast to the actual air temperature. It is computed by factoring in the humidity as well as the air temperature.

PAGASA advised the public to:

• Limit the time spent outdoors.
• Drink plenty of water.
• Avoid tea, coffee, soda and liquor.
• Wear umbrellas, hats, and sleeved clothing outdoors.
• Schedule heavy-duty activities for the beginning or end of the day, when it's cooler.
