Kanpur, Sept. 27 -- Kanpur recorded 175.4 mm rainfall between 8.30 am on Friday and 8.30 am on Saturday, breaking a 76-year record for 24-hour rainfall in the city and also a 45-year record for September. According to weather department records, the 175.4 mm rainfall is the highest in 24 hours in Kanpur since August 21, 1950. It was then that the city had received 213 mm rainfall. As the September rainfall record, this is the first time since 1981 that the month has seen the city receiving such heavy rain. Relentless showers triggered house collapses, flooding and other rain-related incidents that left at least seven people dead across Kanpur and its neighbouring districts. Dr S N Sunil Pandey, principal weather scientist at Chandrashekhar Azad University, said, "Kanpur received 175.4 mm of rainfall during the 24-hour period. The monsoon was fully active and its influence had led to heavy rain and thunderstorms, with similar weather expected to continue till Sunday." Ajay Mishra, the CSA University weather department nodal and technical officer, said a very strong low-pressure area over the Bay of Bengal, along with a cyclonic circulation, had reactivated the monsoon over Uttar Pradesh just before its expected withdrawal. The India Meteorological Department has issued an alert for winds of 40-50 kmph and lightning until September 27. The rain, which began on Thursday night, continued through Saturday morning. Large parts of Kanpur were waterlogged, drains overflowed and several roads became difficult to negotiate. More than 10 houses collapsed in different villages of Ghatampur, though residents escaped unhurt. Three people died due to house collapses in Hamirpur. A boy in Fatehpur died after a house wall collapsed. A 70-year-old man was buried under a collapsed mud house in Banda and died. Two men died while working on an electrical fault in an apartment in Kanpur after a rainwater-induced seepage. Waterlogging was reported across Kanpur.
