LPA's trough, ridge of HPA to bring cloudy skies, scattered rains over PH

The trough of a Low Pressure Area (LPA) will be affecting Mindanao while the ridge of a High Pressure Area (HPA) will extend over the eastern section of Northern Luzon  on Friday, PAGASA reported.

Davao Region and SOCCSKSARGEN will have cloudy skies with scattered rain showers and thunderstorms due to the trough of the LPA with possible flash floods or landslides occurring due to moderate to at times heavy rains.

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

The Heat Index in Metro Manila is higher on Thursday with 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 extreme caution as some people may experience heat cramps and heat exhaustion and continuing activity could lead to heat stroke.

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
