Intense overnight thunderstorms with gusts of wind and continued rain led to Mumbai ‘s highest 24-hour October rainfall in 10 years.
The meteorological bureau has said that the entire Konkan coast, including Mumbai, is expected to receive heavy to very heavy rains with the possibility of extremely heavy rains on Thursday.
Due to intermittent episodes of heavy rain, Mumbai recorded its second highest monthly rainfall (144.8 mm) in a decade. The highest was in 2012 when 197.7 mm of rain was recorded in October.
The Santacruz Meteorological Observatory, representative of the suburbs and Mumbai, recorded 86.5 mm of rain between 8:30 a.m. on Wednesday and 8:30 a.m. on Thursday, with the majority of rainfall recorded during the night (8: 30 pm to 8:30 am).

Between 8.30 a. M. Wednesday and 8.30 a. On Thursday, the Colaba weather station, representative of South Bombay, recorded 115.8 mm of rain. The Indian Meteorological Department (IMD) had no previous rainfall data for Colaba for October, but said this was one of the highest 24-hour rainfall ever recorded for the month.
“The city and suburbs witnessed intense thunderstorm activity overnight with dense cloud cover over Mumbai, located 10 km above the ground, resulting in widespread rain activity. Those who travel early in the morning are likely to face serious difficulties due to waterlogging in low-lying areas, ”said KS Hosalikar, IMD’s deputy general manager for western region.
The maximum precipitation was recorded in Worli (110.8 mm) followed by Navi Mumbai (101 mm) and Mazgaon (97.2 mm). The rest of the Mumbai Metropolitan Region recorded rainfall between 50mm and 85mm during the last 24 hours.
Hosalikar added that heavy cloud cover was observed off the coast of Mumbai Thursday morning. “The well-marked low-pressure area is now over southern central Maharashtra and around southern Konkan. It is very likely that it will move west-northwest and emerge into the Arabian Sea off the coast of Maharashtra, and intensify into a depression over the Arabian Sea over the next 48 hours, ”Hosalikar said.
“Heavy rains are expected during the afternoon and late at night, similar to Wednesday,” Hosalikar said.
