Ten areas across the Philippines are expected to experience dangerous heat index levels ranging from 43°C to 44°C on Holy Monday, the state weather bureau warned.
In its 5 a.m. forecast, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said the following areas may face intense heat:
- NAIA, Pasay City, Metro Manila – 44°C
- Echague, Isabela – 44°C
- Sangley Point, Cavite – 44°C
- Dagupan City, Pangasinan – 43°C
- Tuguegarao City, Cagayan – 43°C
- Subic Bay, Olongapo City – 43°C
- San Ildefonso, Bulacan – 43°C
- Ambulong, Tanauan, Batangas – 43°C
- San Jose, Occidental Mindoro – 43°C
- Dipolog, Zamboanga del Norte – 43°C
PAGASA classifies heat index values between 42°C and 51°C under the “danger” category, where heat cramps, heat exhaustion, and even heatstroke are likely with prolonged exposure. Heat indices between 33°C and 41°C fall under the “extreme caution” level.
The heat index represents the actual temperature felt by the human body when humidity is factored in with air temperature.
Weather Outlook
While hot and humid conditions will prevail in many areas, parts of the country will experience rains due to the frontal system and easterlies.
The frontal system affecting extreme Northern Luzon is expected to bring rains over Batanes, Cagayan, and Apayao.
Meanwhile, scattered rains and thunderstorms caused by easterlies will affect the Zamboanga Peninsula, Basilan, Sulu, and Tawi-Tawi. PAGASA warned that moderate to heavy rainfall in these areas may lead to flash floods and landslides.
The rest of the country may also experience isolated rain showers or thunderstorms, particularly in the afternoon or evening.
Extreme Northern Luzon will have moderate winds and moderate coastal waters, while the rest of the archipelago can expect light to moderate winds and slight to moderate seas.
No low pressure area is expected to enter or form within the Philippine Area of Responsibility, PAGASA added.
