THE weather bureau on Tuesday said it has been monitoring a low pressure area (LPA) inside the Philippine Area of Responsibility.
As of 3 a.m., the LPA was located 295 kilometers south southeast of Kalayaan, Palawan, and embedded along the Intertropical Convergence Zone (ITCZ).
The LPA is unlikely to develop into a cyclone in the next 24 hours, but it will bring scattered rains and thunderstorms across Palawan.
The same weather condition is forecast across Mindanao, Western Visayas, and Negros Island due to the ITCZ.
Scattered rains and thunderstorms caused by the easterlies will also prevail over Eastern Samar, Leyte, and Southern Leyte.
Moderate to heavy rains in the abovementioned areas could result in flash floods or landslides, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.
The rest of the country will experience isolated rain showers or thunderstorms due to the easterlies.
Light to moderate winds and slight to moderate seas continue to prevail across the archipelago.
Meanwhile, PAGASA forecast the heat index to peak at 45°C in Aparri, Cagayan.
A 44°C is forecast in Laoag City, Ilocos Norte; Dagupan City, Pangasinan; Tuguegarao City, Cagayan; ISU Echague, Isabela; Baler (Radar), Aurora; and Tarlac Agricultural University.
The heat index could reach 43°C in Casiguran, Aurora; Infanta, Quezon; Sangley Point, Cavite City; Masbate City; Butuan City, Agusan del Norte; Cubi Point, Subic Bay, Olongapo City; Iba, Zambales; CSLSU Muñoz, Nueva Ecija; and MMSU, Batac, Ilocos Norte.
A 42°C heat index is expected in Sinait, Ilocos Norte; Bacnotan, La Union; Clark Airport; San Ildefonso, Bulacan; Ambulong, Tanauan, Batangas; Daet, Camarines Norte; Legazpi City, Albay; CBSUA-Pili, Camarines Sur; Iloilo City; and Dumangas, Iloilo.
Heat index refers to the temperature felt by the human body when relative humidity is factored in with actual air temperature.
Under “danger” level conditions, ranging from 42°C to 51°C, the public is warned of increased risks of heat cramps, heat exhaustion, and heat stroke with prolonged exposure. (PNA)
