The Celsius is set to touch a new low.
The Met office has predicted that the minimum temperature on Wednesday would be 9 degrees Celsius in Calcutta, the lowest in more than a decade, following a comeback of the chill. And if the wind blows unhindered, the apparent temperature to be felt on the exposed skin will be even lower — around seven degrees.
The last time this winter the minimum temperature has been as low as 10 was on December 27, when the city was experiencing a phase of continuous fog and mist. The lowest minimum in the past decade has so far been 9.3 degrees, recorded on January 22, 2003.
“Nine degrees, if the prediction comes true, will be the lowest in the city in more than a decade,” said an official of the India Metereological Department.
The minimum temperature on Tuesday was 12.2 degrees Celsius, two notches below normal and three less than Monday’s 15.2. The maximum temperature came down from Monday’s 21.2 to 19.3, seven degrees below normal.
“For the first time this year I felt the bite of the cold when I stepped out for a walk on Tuesday morning. The visibility, too, was poor,” said Mandira Maitra, a resident of Golpark.
The absence of any weather system has resulted in a free flow of the North Wind and the return of the chill the city has been missing since the last week of December, the weatherman said.
The North Wind was being blocked over the past few days by two weather systems — a cyclonic circulation over Bangladesh and a high-pressure belt over north Bay of Bengal — which had strengthened the flow of moisture into southern Bengal.
“The twin systems resulted in fog and mist and lowered the visibility. Now that both systems have weakened, the visibility is set to improve,” the weather official said.
“Some districts of south Bengal experienced a cold wave-like situation on Tuesday. But such a phenomenon is unlikely in Calcutta,” the official added.
