Weather conditions in parts of India have shifted from warm and dry to periods of heavy rainfall.

Initially, Bengaluru and Kolkata were forecasted to experience warm, mostly dry conditions with clear or partly cloudy skies. In Bengaluru, temperatures were expected to reach 30°C, while Kolkata faced heat and humidity concerns.

Subsequently, the India Meteorological Department warned of heavy to very heavy showers in Karnataka, specifically affecting Bengaluru and several southern districts, accompanied by thunderstorms and gusty winds. In West Bengal, weather patterns shifted to include scattered light to moderate rain and thunderstorms across Kolkata and South Bengal districts during the Durga Puja period. While gusty winds were expected, officials noted that heavy rain was unlikely to significantly disrupt festivities, with conditions in West Bengal forecasted to improve and become mostly dry later in the week.
