Kolkata, Oct. 30 -- The remnants of extremely severe cyclonic storm Arnab have weakened further into a low-pressure area over north Chhattisgarh and adjoining East Madhya Pradesh, the IMD said on Friday. The associated cyclonic circulation extends up to 4.5 km above mean sea level.
The system triggered widespread rainfall across coastal areas over the past 24 hours, with heavy showers at isolated places. Digha recorded 80 mm of rainfall, while Jangipur and Kharagpur received 60 mm each. Amgachia in East Midnapore recorded the highest rainfall at 90 mm.
Kolkata and several other South Bengal districts are expected to witness light to moderate rain and thundershowers on Saturday. East Midnapore, South 24-Parganas, North 24-Parganas, Kolkata, Birbhum, Murshidabad and Nadia are among the districts where rainfall is forecast at a few places. Thunderstorms, lightning and gusty winds reaching 30-40 kmph are also expected at isolated places.
In North Bengal, Darjeeling, Jalpaiguri, Kalimpong and Alipurduar are under a heavy rainfall warning, till Saturday morning. Rainfall activity is expected to gradually decrease over the following days.
Meanwhile, a separate low-pressure area over the South Andaman Sea and adjoining Andaman and Nicobar Islands is likely to intensify into a depression over the southeast Bay of Bengal around October 31. It is subsequently expected to move west-northwestwards towards the Andhra Pradesh coast.
The IMD clarified that there is currently no weather warning for Bengal in connection with the new system, which remains under continuous surveillance. Dry weather is expected to return to South Bengal from November 4.
