The India Meteorological Department (IMD) released its Tuesday bulletin at 10:30 IST, predicting very heavy to heavy rainfall over southern India and a dry spell over most of the north. The bulletin highlighted a deepening depression over the North Andaman Sea that moved north‑northwestward at 10 km/h, intensifying into a deep depression by 11:30 IST on September 28, 2026. This system is expected to steer toward the northeast Bay of Bengal, potentially affecting the Andaman and Nicobar Islands.
In the northern belt, Uttarakhand will see light to moderate showers in districts such as Uttarkashi, Rudraprayag, Chamoli, Bageshwar and Pithoragarh, while Himachal Pradesh may receive isolated rainfall. Delhi, Haryana and Punjab are projected to remain largely dry, with no heavy rain warning issued for any part of Uttar Pradesh on Tuesday.
The southern focus shifts to Karnataka, where South Interior districts are slated for very heavy rain accompanied by thunderstorms and lightning, a pattern that may persist through October 1. Tamil Nadu, Puducherry and Karaikal are also expected to experience heavy showers on September 29, with the risk of flash floods persisting into the first week of October.
In the northeast, Mizoram, Manipur, Nagaland and Tripura will receive heavy rainfall with thunderstorms and lightning starting September 29, and the IMD expects further heavy activity on September 30. The Andaman and Nicobar Islands will also see thunderstorms as the depression’s influence grows.
Officials have urged residents in the most affected districts to stay alert, keep emergency contact numbers handy, and follow local advisories. The IMD will issue a revised bulletin at 18:00 IST, and state disaster management authorities are on standby to respond to any sudden weather‑related incidents.
