The shear line and the northeast monsoon will continue to dampen most parts of the country on Monday, the weather bureau said.

Scattered rain showers and thunderstorms caused by the shear line will prevail in Visayas, Northern Mindanao, Caraga and Davao Region.

Cagayan Valley, Cordillera Administrative Region and Bicol regions and the provinces of Aurora, Quezon, Marinduque and Romblon will also have rain showers caused by the northeast monsoon.

The Philippine Atmospheric, Geophysical and Astronomical Services Administration said these areas may possibly experience flash floods or landslides due to moderate to heavy rains.

Meanwhile, the northeast monsoon will also cause light rains in the rest of Luzon.

The rest of Mindanao, on the other hand, will have isolated rain showers caused by localized thunderstorms.

Moderate to strong winds and moderate to rough seas will prevail in Luzon, the Visayas, and the eastern section of Mindanao.

Rough to very rough seas are forecast over the northern, eastern, western and southern seaboards of Luzon, the eastern and western seaboards of the Visayas, and the eastern seaboard of Mindanao.

PAGASA advised fishing boats and other small sea vessels not to venture into the sea, and larger sea vessels are also alerted against big waves.

The rest of Mindanao will have light to moderate winds with slight to moderate seas.
