Chandigarh, Jan. 11 -- The city witnessed its coldest night of the season as temperatures dropped to 4degC on Saturday, low enough for the India Meteorological Department (IMD) to classify it as a cold wave condition.

A cold wave condition is declared in the region when the minimum temperature drops below 10degC and is 4.5 to 6.4 degrees below normal, or when the absolute value of the minimum temperature is 4degC or below. If the absolute value of the minimum temperature is 2degC or below, then a severe cold wave is declared.

Though it is unlikely that the night temperatures may drop further, Met officials said the nights will continue remaining chilly but residents can expect afternoons to be sunny.
