The rains pose risks of flash floods, landslides and partial flooding in the northern mountainous provinces, according to the national weather center.

Temperatures in the north are forecast to plunge to 11-14 degrees Celsius at the lowest and even below 5 degrees Celsius in high mountains with a possibility of frost.

Downpours, thunderstorms, whirlwinds, with lightning, hail and strong winds are also expected in the central region until Wednesday.

People in the mountainous regions are advised to refrain from engaging in outdoor activities, as well as keep their cattle, plants and aquatic farms warm to mitigate losses.
