The city’s shower deficit for June, more than 30 per cent, might not be met in the next four days of the month as heavy rain is unlikely at least till Thursday.
The city last received substantial rain on Sunday in intermittent bursts. The clouds, however, thinned on Monday and the summer feeling was back on Tuesday.
“A cyclonic circulation is stretching over Bihar to north Bengal,” said Ganesh Kumar Das, a senior meteorologist at the India Meteorological Department, Calcutta. “It will bring substantial rain to northern districts, like Darjeeling and Malda. In south Bengal, however, the sky will only be partly cloudy.”
Only “light rain, if at all” is predicted for the city in the next 24 to 48 hours.
“The rainfall deficit in Calcutta in the first 26 days of the month is 31 per cent. Northern districts, including Cooch Behar and Darjeeling, have overshot the normal rainfall figure by at least 46 per cent. The situation does not look favourable for the deficit to be made up for by June,” Das added.
“Tuesday was muggy, similar to what it had been before last weekend’s rain,” said schoolteacher Anuradha Roy. “Monday was at least cloudy but the sun was out on Tuesday, making things worse.”
With the cloud cover gone, Tuesday’s temperature shot up — the maximum was 36.2 degrees Celsius, three notches above normal, and the minimum was 27.6, two degrees above normal.
On Monday, both were at the normal mark.
Met officials warned that the temperature might stay a few degrees above normal for at least the next two days.
According to Met records, the city usually receives 283.5mm of rain in June.
This year, with only four days for the month to end, it has received just 174.3mm. It should have rained at least 245mm by now.
“The city received rain on 10 days in June so far. On five of the 10 days, there was less than 4mm of rainfall. Obviously, the rain did not have the kind of cooling effect as a decent shower would have,” said a weather scientist.
