A consistently cloudy sky and persistent rain marked Thursday in Kolkata.
The rain came in multiple spells but none lasted long.
The consistently overcast conditions dragged the Celsius down. As the sun hardly made an appearance on Thursday, the maximum temperature slid to 28.8 degrees, four notches below normal.
A Met official attributed the rain to small clouds formed by the constant flow of moisture-laden southeasterly winds from a well-marked low-pressure area on the Bay of Bengal.
Friday is likely to be cloudy in phases and see more than one spell of rain, said a Met official.
The Met office recorded around 10mm of rain in Alipore on Thursday. Data obtained by the pumping stations of the Kolkata Municipal Corporation suggest many parts of the city were wetter.
In the past 72 hours, the Met office recorded around 65mm of rain in Alipore, the official log book of Kolkata.
The Met office attributed the showers to a low-pressure area on the Bay of Bengal.
A Met official said the system made a slight deviation from the projected track, having a little more impact on Kolkata than it was initially supposed to.
“The system was expected to move south... But it kept moving north and stayed close to north Odisha and the adjoining coastline of East Midnapore in Bengal,” said G.K. Das, director, India Meteorological Department, Kolkata.
The sky is likely to remain “generally cloudy” on Friday, according to the forecast. A couple of spells of rain are likely.
“The weekend is likely to be drier. But a fresh system is expected on the Bay at the start of next week,” said Das.
