Kolkata, Aug 13 (NationPress) The meteorological department has predicted significant rainfall in Kolkata and nearby regions starting Wednesday, as a low-pressure system has developed over the central Bay of Bengal.
This system is pulling moisture from the ocean and is anticipated to strengthen over the next 48 hours before shifting toward the Bengal coastline.
As a result, heavy to very heavy rainfall is expected in various districts of South Bengal, especially in South 24 Parganas, North 24 Parganas, Howrah, and Hooghly. According to the Regional Meteorological Centre in Alipore, the current monsoon trough extends from Jalpaiguri in north Bengal through Haflong in Assam to Manipur.
“The low-pressure area will gain strength in the next 24 hours, resulting in heavy rain across both north and south Bengal,” stated a meteorology official.
The sea is expected to be rough along the coasts of Bengal and neighboring Odisha from Wednesday to Saturday, and fishermen are advised to refrain from going into deeper waters.
