IMD issues a yellow alert for Bengaluru as a low-pressure system brings week-long rain until Oct 26; expect moderate rain, 30°C max and local heavy showers.

The India Meteorological Department has warned Bengaluru of a week-long spell of rain driven by a low-pressure system forming over the southwest Bay of Bengal, and it has issued a yellow alert for the city through October 26. Residents should expect moderate rain on Thursday and Friday, easing to light showers over the weekend while daytime temperatures stay around 30°C and nights near 20°C.
A series of rainbands stretching from South Andhra Pradesh into north Tamil Nadu and south interior Karnataka is fueling continuous rainfall in Bengaluru and nearby districts. The IMD and local forecasts name Hassan, Mysuru, Mandya, Kodagu, Chikkamagaluru and Shivamogga among districts under heavier rainfall alerts, with localized downpours possible — useful to note for commuters, farmers and event planners.
The current pattern also eased Bengaluru’s post-Diwali air quality; the CPCB shows the city’s AQI in the ‘satisfactory’ range (around 94) — better than many other metros experiencing severe smog. Still, motorists and outdoor workers should prepare for wet roads and reduced visibility during peak showers. Authorities are likely to prioritise drainage checks and public transport advisories while farmers in coastal and interior taluks should monitor local warnings for crop and harvest planning.
