The India Meteorological Department (IMD) has put Bengaluru and several districts of Karnataka on alert as a deep depression over the southeast Bay of Bengal moves closer to the coast, with forecasts suggesting it will intensify into Cyclone Montha in the next 24 hours.

At 8:30 am on October 26, the weather system was located about 620 km west of Port Blair, 780 km east-southeast of Chennai, and 830 km south-southeast of Visakhapatnam, moving west-northwest at around 6 km per hour, the IMD's daily weather bulletin noted. The agency said it is likely to develop into a cyclonic storm by Monday (October 27) and further strengthen into a severe cyclone by Tuesday (October 28).

Meteorologists say that as the system intensifies, moisture-laden winds from the Bay of Bengal will bring intermittent rain to Bengaluru, especially in the evenings. Light waterlogging and traffic disruptions are possible in low-lying areas.
Residents have been advised to stay updated on IMD forecasts, avoid unnecessary travel during heavy rain, and secure loose outdoor items as a precaution. Meanwhile, a separate depression over the Arabian Sea is moving southwest and is not expected to affect the Karnataka coast, the IMD stated.
