The center has issued a warning for the possibility of snowfall and frosty weather in high mountainous areas.

Various areas in the northern region, particularly those in mountainous areas, are experiencing severe cold conditions, with temperatures dropping to nearly zero degrees Celsius.

Prolonged rains have exacerbated the chilly conditions.
