Kolkata News

Kolkata: The city and its neighbouring districts could be lashed by heavy to very heavy rain under the impact of a low-pressure area on Monday. The rain could be accompanied by wind blowing at 30kmph-40kmph and may continue till Tuesday. Along with Kolkata, Nadia, Howrah, North 24 Parganas and West Midnpaore are likely to be lashed by rain on Monday. Thunderstorms with lightning and wind at 40kmph-50kmph have also been predicted in South 24 Parganas and East Midnapore.
The showers could lose intensity on Tuesday and Kolkata could remain dry subsequently, said the Met office. Heavy rain has also been predicted across north Bengal from Monday to Wednesday.
The city was cloudy with intermittent showers on Sunday and received 0.5mm rain till 5.30pm. But Salt Lake and Dum Dum recorded 14mm and 21mm rain respectively.
The low-pressure area triggering the rain lay over Telangana on Sunday along with an associated cyclonic circulation that extended up to 5.8km from the sea level. According to an IMD bulletin, it has tilted southwestwards.
Even though the system was far from Bengal, strong southeasterly winds from Bay of Bengal have been carrying in moisture. “Clouds are moving into south Bengal and we expect heavy to very heavy rain at one or two places in Kolkata, Nadia, South 24 Parganas and Howrah on Monday. There will be a strong wind as well, especially in the coastal districts of East Midnapore and South 24 Parganas and areas adjoining these places,” said deputy director-general of meteorology Sanjib Bandopadhyay.
Kolkata has received almost double the normal volume of rain — 96% above the normal mark — in September and Gangetic Bengal has recorded 31% excess rain so far this monsoon from June 1-September 30. While Kolkata’s overall rain count this monsoon has been 31% above normal, Bengal has received 15% excess rain.
The city had received 142mm rain on September 20, making it the rainiest September day in Kolkata since September 25, 2007, when the city had received 174.4mm rain.
