A potential cyclone—a shallow low-pressure area—east of Eastern Visayas dissipated early today, but state weather forecasters said rain is still expected over parts of Luzon for the day.
The Philippine Atmospheric Geophysical and Astronomical Services Administration said a monsoon trough may bring rain to Southern Luzon during the day, and Northern Luzon in the evening.
"Monsoon trough ang nakakaapekto sa Southern Luzon. Magpapaulan pero hindi naman malawak sa Eastern at Southern Luzon. Sa gabi sa Northern Luzon naman," PAGASA forecaster Jun Galang said in an interview.
He said rain may be expected throughout the rainy season.
Galang also said the SLPA nearing Eastern Visayas as of Wednesday had dissipated. It would have been codenamed "Butchoy" had it intensified into a cyclone.
Meanwhile, PAGASA's 5 a.m. bulletin said Eastern and Southern Luzon and Northeastern Mindanao will experience mostly cloudy skies with scattered rain showers and thunderstorms.
The rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms, it added.
Moderate to strong winds from the southwest will prevail throughout the archipelago, and coastal waters will be moderate to rough.
