MANILA – According to the weather bureau, most parts of the Philippines will experience fair weather with isolated rain showers on Friday (31 May 2024).

However, a frontal system affecting extreme Northern Luzon will bring scattered rain showers and thunderstorms to Batanes and the Babuyan Islands.

These areas may experience moderate to heavy rains, potentially leading to flash floods and landslides, warned the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

“The rest of the country will experience fair weather with isolated rain showers,” stated Aldczar Aurelio of PAGASA.

Light to moderate winds and slight to moderate seas are expected nationwide.

PAGASA also monitors a tropical cyclone located 955 km west of Northern Luzon, outside the Philippine Area of Responsibility. “The tropical cyclone is moving west-northwest at 10 kph and is heading towards China,” Aurelio added.

Meanwhile, more than 40 areas are forecasted to experience danger-level heat indices, with temperatures peaking at 47°C in Aparri, Cagayan.

The heat index, which measures how hot it feels when humidity is combined with air temperature, could reach 46°C in Laoag City, Ilocos Norte; Dagupan City, Pangasinan; and Tuguegarao City, Cagayan.

PAGASA has forecasted heat indices of 42°C to 45°C in the following areas:

  • MMSU, Batac, Ilocos Norte
  • Baler, Aurora
  • Casiguran, Aurora
  • Alabat, Quezon
  • Catarman, Samar
  • Sinait, Ilocos Sur
  • Bacnotan, La Union
  • ISU Echague, Isabela
  • Infanta, Quezon
  • Virac, Catanduanes
  • Catbalogan, Samar
  • Tacloban City, Leyte
  • Butuan City, Agusan del Norte
  • Sangley Point, Cavite
  • Ambulong, Tanauan, Batangas
  • Masbate City, Masbate
  • CBSUA-Pili, Camarines Sur
  • Mambusao, Capiz

  • Dumangas, Iloilo
  • Mactan International Airport, Cebu
  • Siquijor, Siquijor
  • VSU-Baybay, Leyte
  • Dipolog, Zamboanga del Norte

With heat indices ranging from 41°C to 51°C, there is an increased likelihood of heat cramps and heat exhaustion. Prolonged exposure to the sun could also lead to heat stroke.

Despite the onset of the rainy season, PAGASA has noted that several areas in the country may continue to experience high heat indices.
