‘There may be isolated heavy rainfall in various dists of South Bengal’

Kolkata: The Regional Meteorological Centre in Alipore predicted that there may be isolated rainfall in several districts of South Bengal districts at the beginning of the week as a low pressure will form over Bay of Bengal on July 18.

The city and several parts of South Bengal received overnight rainfall.

“There may be isolated heavy rainfall in the various districts of South Bengal. The intensity of rainfall in North Bengal started reducing already and the situation will further improve in the next 24 hours,” MeT office said.

There may be heavy rainfall in the coastal districts of Bengal in the next 48 hours. A low pressure will form over Bay of Bengal which will trigger rainfall in South Bengal. The districts like East Midnapore, North 24-Parganas, South 24-Parganas in South Bengal will receive heavy rainfall.

The low pressure may further intensify into depression. However, the intensity of rainfall in North Bengal reduced. A cyclonic circulation may be created over Bay of Bengal after July 18.

There have been several cyclonic circulations formed in several parts of the country. The districts like Jhargram, Bankura and Purulia in South Bengal may also witness rainfall in the next 24 hours.

Due to anticipation of formation of North-South trough and strong moisture incursion from Bay of Bengal, enhanced rainfall activity and heavy to very heavy rainfall occurred over North Bengal for the past few days.

The onset of monsoon in South Bengal has been delayed this year by El Nino and Cyclone “Biparjoy”. Monsoon was expected to enter South Bengal on June 11 but hit the region two weeks late. There was scattered rainfall in Gangetic Bengal last week but it failed to bring relief to the people in South Bengal from hot and humid conditions.
