CLOUDY skies and rains may prevail across the country during the Barangay and Sangguniang Kabataan elections and Undas holidays next week, according to the state weather bureau PAGASA on Friday.

The Northeast Monsoon (Amihan), shear line, and a possible occurrence of a low pressure area will affect the entire archipelago from October 30 to November 3, PAGASA said in its special weather outlook.

Bicol Region, Visayas, Caraga, and Quezon province will have cloudy skies with scattered rain showers and thunderstorms from October 30 to 31 due to the combined effects of the shear line and LPA.

The rest of the country will have isolated rain showers or thunderstorms, mostly in the afternoon or evening.
