The IMD stated that a cyclonic circulation over Bangladesh and its surrounding areas extends up to 1.5 km above the mean sea level and is causing strong moisture incursion from the Bay of Bengal. The maximum temperature is very likely to fall further by 2-4 degrees with no large change thereafter.
On Tuesday, IMD issued an orange alert (be prepared) for heavy rain and thunderstorms in several districts of southern Bengal. There is a high chance of heavy rainfall between 7-11 cm in the districts of Jhargram, East and West Midnapore, and South 24 Parganas.
Additionally, there may be thunderstorms with gusty wind speeds of 50-60 kmph in one or two places in Bankura, Birbhum, Purulia, Jhargram, East and West Midnapore, North and South 24 Parganas, and East and West Burdwan districts.
