MANILA: Most parts of the country will continue to experience warm weather and isolated rain showers due to the easterlies, the weather bureau said Wednesday.The intertropical convergence zone (ITCZ) affecting southern Mindanao, however, will bring scattered rain showers and thunderstorms over the Davao Region, South Cotabato, Sarangani, Sultan Kudarat, Basilan, Sulu, Tawi-Tawi, Zamboanga del Sur, and Zamboanga Sibugay.Moderate to heavy rains in those areas could result in flash floods or landslides, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said.The rest of the country will have isolated rain showers caused by the easterlies and localized thunderstorms.PAGASA forecaster Obert Badrina said no weather disturbance was monitored inside and outside the Philippine Area of Responsibility (PAR)."It is likely that no tropical cyclone will enter or develop inside PAR throughout the week," he said.Meanwhile, temperature is forecast to reach 38°C in Tuguegarao; 35°C in Metro Manila, and 34°C in Kalayaan Islands and Puerto Princesa.PAGASA forecast heat indices of 42°C to 45°C in the following areas:NAIA - 42°CPAGASA Science Garden, Quezon City - 42°CDagupan City, Pangasinan - 44°CBacnota, La Union - 42°CTuguegarao City, Cagayan - 43°CEchague, Isabela - 43°CClark Airport, Pampanga - 42°CMuñoz, Nueva Ecija - 43°CBaler, Aurora - 42°CCasiguran, Aurora - 42°CSubic, Olongapo City - 42°CSangley Point, Cavite - 43°CTanuan, Batangas - 42°CInfanta, Quezon - 42°CCalapan, Oriental Mindoro - 42°CSan Jose, Occidental Mindoro - 42°CCoron, Palawan - 42°CPuerto Princesa, Palawan - 44°CAborlan, Palawan - 44°CVirac, Catanduanes - 43°CMasbate Ciy, Masabate - 42°CPili, Camarines Sur - 43°CRoxas, Capiz - 45°CIloilo City, Iloilo - 42°CDumangas, Iloilo - 42°CGuiuan, Eastern Samar - 43°CDipolog, Zamboanga del Norte - 43°CZamboanga City, Zamboanga del Sur - 45°CDavao City, Davao del Sur - 42°CCotabato City, Maguindanao - 43°CButu an City, Agusan del Norte - 43°CHeat index is what the temperature feels like to the human body when relative humidity is combined with the air.Under danger levels or heat indices of 41°C to 51°C, heat cramps and heat exhaustion are likely.
