MANILA, Philippines —The easterlies and a frontal system will prevail in the next 24 hours, bringing cloudy skies and scattered rains, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (Pagasa) said on Sunday.
The easterly winds which pass through the Pacific Ocean will affect Caraga, Eastern Samar, and Southern Leyte where cloudy skies with scattered rains and thunderstorms are likely, weather specialist Veronica Torres said.
The easterlies will also affect Metro Manila and the rest of the country where partly cloudy to overcast skies with isolated rain showers or thunderstorms are likely.
Meanwhile, Torres said Batanes will have scattered rains and isolated thunderstorms due to the frontal system within the day.
“Flash floods or landslides due to moderate to at times heavy rains would be possible,” she said in a 5 a.m. forecast.
A frontal system is defined as a “transition-boundary separating two air masses of contrasting properties (temperature and humidity).”
“Simply put, fronts form when one kind of air mass enters an area occupied by another kind of air mass,” Pagasa chief Nathaniel Servando explained.
Pagasa said Metro Manila would likely have a heat index of 41 degrees Celsius on Sunday, which falls under extreme caution category, while the highest could be in Negros Occidental at 44 degrees Celsius.
