The rain dragged the maximum temperature down to 27.1°C, this summer’s lowest.Alipore Met office has predicted more rain on Wednesday, but with reduced intensity. Prior to Tuesday, 40.3mm rain on June 27 was this monsoon’s single-day highest.Three factors — a low-pressure area, a cyclonic circulation and a strong monsoon flow — combined on Tuesday to trigger the night-long showers. While Monday saw pockets of south Kolkata get more rain than neighbourhoods in the north, the incessant rain that started around 2am on Tuesday was more uniform. Most of the day’s rainfall was recorded between 2am and 8am.The single-day rain count for Dum Dum was higher than Kolkata at 99.3mm while Salt Lake recorded 90mm. “The low pressure over Gangetic Bengal is moving very slowly, causing uniform rain. This system will gradually move away towards Jharkhand and Chhattisgarh in the next two days and weaken. Hence, we expect the intensity of rain to decrease in Kolkata by Wednesday. But some western districts will continue to receive heavy spells of rain,” said meteorologist HR Biswas, head of the weather forecast section at Regional Meteorological Centre Kolkata.According to an IMD special bulletin, the low-pressure area with an associated cyclonic circulation and a strong monsoon flow will continue to trigger rain in many parts of south Bengal, including Kolkata, for at least another four days.According to the city’s Met calendar, July is the rainiest month of the year.With June’s total monthly rain count at 241.5 mm, which is normal for the month, Met officials expect July rain to be normal as well.Continuous rain pushed the maximum temperature to 27.1°C, the lowest this summer and 5.4°C below normal. The minimum temperature also dipped to 25°C, which was 1.8°C below normal. The mercury is likely to climb slightly on Wednesday but is still expected to stay below normal.
