Ridge of HPA over eastern Luzon, localized thunderstorms to bring isolated rains over parts of PH

The ridge of a High Pressure Area (HPA) will continue to extend over the eastern section of Luzon on Friday, PAGASA reported.

Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms due to localized thunderstorms with possible flash floods or landslides during severe thunderstorms.

PAGASA forecasted heat index at 40 degrees Celsius at the NAIA, Pasay City station and 39 degrees Celsius at the Science Garden in Quezon City.

Based on the heat index chart, the public is advised to take precaution against heat cramps and heat exhaustion, and heat stroke is possible with continued exposure.

The heat index is a measure of how hot it really feels when factoring in the relative humidity at a given location.

In order to prevent heat-related illnesses, the weather bureau is advising the public to do the following:

Limit the time outdoors

Drink plenty of water

Avoid tea, coffee, soda or liquor

Wear umbrellas, hats, sleeved clothing outdoors

Schedule heavy-duty activities at start or end of the day when it's cooler

The wind speed forecast for the eastern section of Luzon is light to moderate moving in the east to southeast direction with slight to moderate coastal waters.

The rest of the country will experience light to moderate wind speed moving in the east to northeast direction while coastal waters will be slight to moderate.

Sunrise will be at 5:40 a.m., sunset at 6:11 p.m. — BAP, GMA Integrated News
