The shear line or tail-end of the frontal system could bring scattered light to, at times, heavy rains over Bicol region and Quezon province within the next 24 hours, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Friday afternoon, Nov. 19.
Weather specialist Raymond Ordinario said the low pressure area (LPA) off Catanduanes has already dissipated but the prevalence of the shear line may bring heavy rains that could trigger flash floods or landslides in the affected areas.
Palawan, Visayas, and Mindanao will have partly cloudy to cloudy conditions with isolated rain showers due to localized thunderstorms, however, PAGASA warned that severe thunderstorm activities may sometimes trigger flash floods or landslides.
Meanwhile, Metro Manila and the rest of Luzon will continue to experience partly cloudy to cloudy skies with isolated light rains due to the northeast monsoon, locally called "amihan."
Ordinario added that no gale warning is in effect as of Friday afternoon, thus sea travel is safe even for fisherfolk and others with small sea vessels.
PAGASA said moderate to rough seas may prevail over northern Luzon, while slight to moderate seas will likely persist over the rest of the country.
