MANILA, Philippines — The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported that cloudy skies with rains are expected to affect the country on Sunday.

Shear line will bring overcast skies, scattered rain showers and thunderstorms to parts of northern Luzon, particularly in Batanes and Babuyan Islands.

Metro Manila and the rest of the country will also see isolated rain showers and thunderstorms, primarily in the afternoon and evening, due to the influence of the easterlies.

The state weather bureau said that the heat index in Metro Manila will reach danger levels, with the Ninoy Aquino International Airport (NAIA) in Pasay City expected to hit 43 degrees Celsius.

The heat index, or apparent temperature, considers both humidity and air temperature to show how hot it actually feels.

The following are the areas that could hit “danger” level on Sunday:

  • Alabat, Quezon - 42°C
  • Ambulong, Tanauan, Batangas - 44°C
  • Bacnotan, La Union - 44°C

In the "danger" classification, temperatures between 42°C and 51°C can cause heat cramps, heat exhaustion, and increase the risk of heat stroke with prolonged sun exposure.
