Manila: The Intertropical Convergence Zone (ITCZ) will bring scattered rains and thunderstorms across Mindanao and the Visayas, the weather bureau announced on Saturday. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) indicated that Palawan will also experience similar weather patterns, as mentioned in their 4 a.m. bulletin.
According to Philippines News Agency, the easterlies are expected to cause partly cloudy to cloudy skies with isolated rain showers or thunderstorms over Metro Manila and the rest of the country. Despite these conditions, the entire archipelago will continue to experience light to moderate winds along with slight to moderate seas.
Meanwhile, the heat index is predicted to peak at 45°C in Aparri, Cagayan; Laoag, Ilocos Norte; and Dagupan, Pangasinan. A 44°C heat index is forecasted for Tuguegarao City, Cagayan, and Subic Bay, Olongapo City.
Various locations, including Sinait, Ilocos Sur; Batac, Ilocos Norte; Echague, Isabela; Baler, Aurora; Casiguran, Aurora; Infanta, Quezon; and Iloilo City, Iloilo, may experience a 43°C heat index. Additionally, a 42°C heat index is likely in Bacnotan, La Union; Calayan, Cagayan; Iba, Zambales; Hacienda Luisita, Tarlac City; San Jose, Occidental Mindoro; and Masbate City, Masbate.
The heat index signifies the temperature the human body feels when relative humidity is considered alongside the actual air temperature. Prolonged exposure to "danger" level conditions, ranging from 42°C to 51°C, could result in heat cramps, heat exhaustion, and heat stroke.
