Cyclone Arnab: IMD issues red alert as Andhra Pradesh, Odisha brace for landfall. Check rainfall forecast

A deep depression over the east-central and adjoining west-central Bay of Bengal has intensified into Cyclonic storm Arnab, triggering a high-priority red alert across coastal Andhra Pradesh, Yanam, and southern Odisha as authorities race against time to prepare for a severe landfall.   

According to the India Meteorological Department's (IMD) weather bulletin, the system was centered at 05:30 hrs IST on October 26, 2026, near latitude 15.4°N and longitude 88.9°E — roughly 590 km northwest of Sri Vijaya Puram in the Andaman Islands, 610 km southeast of Gopalpur, 650 km east-southeast of Visakhapatnam, and 910 km east of Bapatla.

Moving west-northwestwards at a speed of 15 kmph, the tempest is forecast to escalate into a severe cyclonic storm by the midnight of October 26 and transform into a very severe cyclonic storm the following day.   

The IMD warns that the system will cross the Andhra Pradesh and Yanam coasts close to Yanam and between Bapatla and Visakhapatnam by the forenoon of October 28, packing maximum sustained wind speeds of 115 to 125 kmph, gusting up to 140 kmph.

Destructive storm surges reaching 1.0 to 1.5 meters above astronomical tide are projected to inundate low-lying areas, with peak surges expected over East Godavari and Yanam.
