Parts of southern India are expected to see unsettled weather this week, with the India Meteorological Department (IMD) forecasting heavy to very heavy rainfall in areas of Andhra Pradesh, Tamil Nadu, Kerala and Karnataka between October 17 and 23, 2026. Thunderstorms, lightning and gusty winds are also possible in affected areas.
The forecast is regional, so conditions can differ significantly between districts and even nearby localities. Coastal areas may face additional marine-weather risks, and advisories for fishermen should be followed where issued.
Precautions for residents
- Check the latest IMD bulletin and district-level warnings before travelling.
- Avoid walking or driving through flooded roads and underpasses.
- Keep away from exposed locations, isolated trees and metal structures during lightning.
- Secure loose outdoor objects and be cautious around electrical wires.
- Allow extra travel time and follow official traffic and emergency instructions.
What Bengaluru residents should do
Residents of Bengaluru should rely on the latest city and district advisories rather than assuming that a statewide warning applies uniformly. Rain can reduce visibility and slow traffic, while waterlogging may develop quickly in low-lying stretches. Check road conditions before leaving and avoid unnecessary travel during intense downpours.
Forecasts can change as weather systems evolve. For the most reliable updates, follow IMD bulletins and local disaster-management authorities. This report summarises the available forecast and is not a substitute for official emergency instructions.
