A cold front is moving down from the north, bringing chill weather to northern border provinces, the Central Hydrometeorology Center said November 11.

It will blanket the border provinces on November 12 before moving over other northern provinces and then the central region on November 13.

Temperatures at all these places will drop to 20 degrees Celsius in the day and 15 – 16 Celsius in the evening.

The southern and south central regions would, however, continue to enjoy sunny weather.
