Mumbai, July 02 (ANI): The residents of Mumbai on Wednesday enjoyed the very first rainfall of monsoon after suffering from a month long heat wave. However, the heavy rainfall though fruitful for the people, also caused trouble as there was immense waterlogging in Andheri and some flights were also reportedly delayed due to bad weather condition. May and June are usually the hottest months of the year in India with temperatures often in the range of 42 to 47 degrees Celsius at many places.
