According to data from the Indian Meteorological Department (IMD) monitoring station located in the city and suburbs of Santa Cruz, the city recorded a total of 253 mm of rainfall (thunderstorm) in about 4.5 hours on Friday morning. This is by far the strongest rainfall event of the season and the second-largest daily rainfall (July) on record in the past 10 years. According to IMD data, the city had previously witnessed 375.2 mm of rain on July 2, 2019.
The rain on Friday morning was mainly concentrated in the western suburbs and parts of central Mumbai. The day’s thunderstorm data showed a big difference in spatial distribution, which experts attributed to the east wind blowing clouds away from southern Mumbai. Therefore, at 8:30 am on Friday, the IMD Observatory in Colaba only recorded 13mm of rain.
The total seasonal rainfall in the city is 1545 mm, exceeding the normal rainfall of 1332.5 mm expected by the end of July. According to IMD, the normal rainfall between June 1 and July 16 is 935.8 mm. In other words, as of July 16, Mumbai’s rainfall was 65% higher than normal.
