Last week, Nagpur received extremely heavy rains leading to floods in most parts and water gushing into at least 10,000 homes. According to the IMD, the city had received 109 millimetres of rain in three hours, including 90 mm between 2 am and 4 am on September 23. The Ambazari Lake, the city's largest such waterbody, and the Nag river breached their boundaries, leading to severe flooding.
