A heat index between 41℃ and 54℃ is under what the PAGASA considers as dangerous level due to the high likelihood of heat cramps and heat exhaustion.
The highest heat index so far in 2021 was recorded in Dagupan City, Pangasinan on May 14 at 53℃.
PAGASA said the whole country will continue to have hot and humid weather conditions on Monday, May 17, due to the prevalence of the easterlies.
However, there is a chance of isolated rain showers or thunderstorms by afternoon or evening.
Due to the possibility of sudden heavy rains during severe thunderstorms, PAGASA advised the public to take necessary precautionary measures in case of flooding or landslides.
