MANILA – Rain showers are expected over several areas in Luzon due to the southwest monsoon (habagat) and a frontal system, according to the weather bureau on Thursday (30 May 2024).

The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) reported that the habagat will bring scattered rain showers and thunderstorms to the Ilocos Region and the provinces of Zambales, Bataan, Occidental Mindoro, and Palawan.

In addition, scattered rain showers and thunderstorms caused by the frontal system will affect Batanes and the Babuyan Islands.

PAGASA warned that moderate to heavy rains in these areas could lead to flash floods or landslides.

The rest of the country will see isolated rain showers from localized thunderstorms, with moderate winds and seas expected across Luzon. Other regions will experience light to moderate winds and slight to moderate seas.

Despite the onset of the rainy season, PAGASA forecasts that some areas will face heat indices reaching danger levels. The heat index, which combines air temperature and relative humidity to reflect how hot it feels, could peak at 47 degrees Celsius in Aparri, Cagayan, and Baler, Aurora Province. ISU Echague in Isabela and Casiguran in Aurora may experience heat indices of 46 degrees Celsius.

Areas with forecasted heat indices of 42 to 45 degrees Celsius include:
