CITY OF SAN FERNANDO The Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) is urging the public to take precautionary measures against excessive heat and humid weather which is forecasted to prevail in the coming months.

In its 11:00 am, March 27 forecast, Pagasa said that heat index temperatures ranging between 38 to 45 degrees Celsius fall under the state weather bureau's "Extreme Caution and Danger" category which means prolonged exposure under the sun may lead to dehydration, heat exhaustion, heat cramps, and heat stroke.

On Monday, Pagasa said that temperatures in Angeles City ranged from 24 to 36 degrees Celsius; in Metro Manila from 25 to 34 degrees Celsius; and in Tuguegarao City from 24 to 36 degrees Celsius, which could reach up to 38 degrees Celsius.

There are almost no cloud clusters inside the Philippine Area of Responsibility.

"So we are expecting hot weather in most parts of the country although isolated rain showers and thunderstorms caused by the easterlies and localized thunderstorms may also be experienced in the coming days," PAGASA weather specialist Obet Badrina said.

He added that no tropical cyclone is expected to form or enter the Philippine Area of Responsibility this week.

Badrina urged the public to stay hydrated and avoid going outdoors at noontime when the heat is most intense to avert exhaustion, cramps and stroke which can be fatal and dangerous.

Other important precautionary measures advised by Pagasa include wearing light and breathable clothes; avoiding drinking sugary drinks like soda, and those containing caffeine like coffee and tea, as well as alcohol and other diuretics which can cause dehydration amid intense heat; and avoiding intense physical activities at noontime and in the afternoon which can lead to heat cramps or heat stroke.

Pagasa officially declared the start of the dry season which is characterized by warm temperatures in different parts of the country.

The Department of Health (DOH) warned of other common illnesses during summer and sweltering heat.

The DOH urged the public to apply sun protection lotions for additional protection, and if going to resorts, to ensure that the water in the swimming pools are clean and free of bacteria to avoid ear infections, eye infections and gastrointestinal disease, and for those who will go outside to wear hats or use umbrellas if going out between 10 am and 3 pm.
