Cyclone Arnab strengthened over the Bay of Bengal from a deep depression into a cyclonic storm and then, by the IMD's Monday 5:30pm bulletin, a severe cyclonic storm. It was at about 15.6 N, 87.3 E, roughly 490 km east-south-east of Visakhapatnam and 730 km east of Bapatla, moving west-northwest at 17 km/h. The IMD expects a very severe cyclonic storm within 12 hours.
It is forecast to cross the Andhra Pradesh and Yanam coasts between Bapatla and Visakhapatnam by the forenoon of 28 October, with sustained winds of 115-125 km/h and gusts to 140. The IMD expects the storm to keep moving west-northwest until the evening of 27 October, then turn north-west towards the coast. Odisha faces very heavy rain on 27 October, extremely heavy rain on 28 October and very heavy rain on 29 October, with heavy rain on 30 October. Impacts are expected to continue into 29 October and recede substantially from 30 October; no warning is listed for 31 October or 1 November.
Preparations are under way on both sides of the coast. In Andhra Pradesh, officials identified about 5.7 lakh (570,000) vulnerable residents and put 10 NDRF teams and 11 SDRF teams on standby, with control rooms and relief centres being prepared; reporting did not establish that all of those residents had been moved. The utility APEPDCL has opened 30 divisional and 11 circle-level control rooms. On Monday the Centre placed the Army, Navy, Air Force and Indian Coast Guard on standby for rescue and relief.
In Odisha, schools, colleges and Anganwadi centres in Ganjam, Gajapati, Rayagada, Koraput and Malkangiri close on 28 and 29 October, and those districts are under a red warning for very heavy rain. The state has begun moving residents out of low-lying and landslide-prone southern districts. It has 302 rescue teams on standby, and 225 fire service teams and NDRF personnel have been deployed. Fishing is suspended, and more than 4,800 boats have returned to the Kakinada coast.
Across the bay, Sri Lanka's meteorology department issued a red warning on Monday for strong winds and rough seas as Arnab intensified, according to a news roundup. In Odisha the IMD expects heavy to very heavy rain, strong winds and possible landslides in several districts, with widespread rain on 28 October and isolated extremely heavy falls in some places.
Bangladesh proposed the name 'Arnab', which comes from the cyclone-name list adopted in April 2020; in Bengali it means 'sea' or 'ocean'.
