A consistently cloudy sky and intermittent rain marked Sunday in Kolkata.
North Kolkata and northern suburbs got more rain than south Kolkata.
Between 8.30am and 5.30pm, the Met office recorded over 30mm of rain in Salt Lake.
In comparison, Alipore got around 5mm in the same period, said a Met official.
“A low-pressure trough that is responsible for the current weather conditions is likely to persist for a few more days. The city sky is likely to be overcast on Monday and Tuesday as well. More showers are expected over the next 48 hours,” said a Met official.
“Many small cloud masses made their way to Kolkata by Sunday afternoon. The clouds came from Jharkhand via Paschim Medinipur, Bankura and Bardhaman. The clouds over north Kolkata were more potent than those over the southern parts,” . Hooghly and North 24-Parganas also got multiple spells of rain,” the official said.
The sky was cloudy throughout Sunday. Around 2pm, the white marble monument of Victoria Memorial stood in sharp contrast against the backdrop of a dark sky. It felt like a spell of heavy rain was imminent.
However, the rain was not as widespread as expected.
Around 12.30pm, Swinhoe Street and adjoining areas in the south were getting drenched. But parts of Kasba, barely 2km away, were dry.
“A trough of low pressure is extending from Rajasthan to the northwest Bay of Bengal, via Jharkhand and Gangetic Bengal. The system is drawing a lot of moisture from the Bay of Bengal. The moisture is leading to cloud formation. The clouds are then moving eastwards, towards the Bay,” said G.K. Das, director, India Meteorological Department, Kolkata.
The current wet spell began on Friday night, with two back-to-back squalls hitting Kolkata. The thundershowers on Friday night were marked by strong gusts of wind and frequent bolts of lightning. The winds on Sunday were not as powerful as they were on Friday.
“When the conditions are consistently overcast, the clouds become heavier and move slowly. The wind speed gets diminished,” said Das.
The overcast conditions have dragged the mercury down significantly.
On Sunday, the maximum temperature in Alipore was 26.5 degrees, eight notches below normal.
The minimum temperature was 21.6 degrees, two notches below normal.
