MANILA – The weather bureau on Monday said the trough of a low pressure area (LPA) outside the Philippine Area of Responsibility (PAR) will bring rain showers over parts of Mindanao.
"The LPA is unlikely to develop into a tropical cyclone. However, cloud clusters were formed due to the LPA's trough, and would bring rains, particularly in Basilan, Sulu, and Tawi-Tawi," Obet Badrina of the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.
Scattered rain showers and thunderstorms are forecast in those areas, and moderate to heavy rains could result in flash floods or landslides.
Badrina said the LPA could dissipate within the day.
"There is a slim chance for the country to experience (a) tropical cyclone this week," he added.
Meanwhile, he said warm weather would continue to prevail across Luzon and the Visayas.
"Isolated rains will be experienced due to localized thunderstorms," Badrina said.
The temperatures in Tuguegarao could reach up to 38 °C and up to 36 °C in Metro Manila.
Up to 35 °C temperature is forecast in Zamboanga City, and up to 34 °C in Kalayaan Islands and Puerto Princesa.
Heat indices of 42 °C and 43 °C are forecast in the following areas:
Dagupan City, Pangasinan – 43°C
Aparri, Cagayan – 43°C
Tuguegarao City, Cagayan – 42°C
Infanta, Quezon - 44°C
Puerto Princesa City, Palawan – 44°C
Aborlan, Palawan – 44°C
Legazpi, Albay – 43°C
Virac, Catanduanes – 43°C
Masbate City, Masbate – 43°C
CBSUA-Pili, Camarines Sur – 45°C
Roxas City, Capiz – 42°C
Iloilo City, Iloilo – 42°C
Dumangas, Iloilo – 42°C
Catarman, Northern Samar – 42°C
Guiuan, Eastern Samar – 43°C
Heat index is what the temperature feels like to the human body when relative humidity is combined with the air.
Under danger level or 41 °C to 51 °C heat indices, heat cramps and heat exhaustion are likely. Continued exposure to the sun could also cause heat stroke.
Meanwhile, light to moderate winds and slight to moderate seas will prevail across the archipelago, PAGASA said. (PNA)
