Deep Depression Crosses Odisha-West Bengal Coast, IMD Warns of Extremely Heavy Rain

A Deep Depression over the northwest Bay of Bengal crossed the West Bengal–Odisha coast near Digha during the early hours of Tuesday, July 28, triggering widespread rainfall and prompting the India Meteorological Department (IMD) to issue warnings for extremely heavy rain, strong winds, rough sea conditions and possible flash floods across several states.
According to the IMD’s latest national bulletin issued at 9:00 AM IST, the system moved west-northwestwards at a speed of 7 kmph and crossed the coast between 12:30 AM and 1:30 AM IST near Digha. At 5:30 AM, the centre of the Deep Depression was located over north coastal Odisha and adjoining Gangetic West Bengal, about 30 km west-northwest of Digha, 30 km northeast of Balasore, 50 km east-southeast of Baripada, 160 km southeast of Jamshedpur, and 170 km east of Keonjhargarh.
The weather system is expected to continue moving west-northwestwards across north Odisha, south Jharkhand and north Chhattisgarh during the next 24 hours, bringing widespread rainfall and gusty winds across eastern and central India.
