Most localities reported rainfall between 40 to 70mm, while Navi Mumbai reportedly received more than 120mm of rain in the 24 hours ending Wednesday morning, as per data shared by the IMD. Belapur received nearly 150mm, the highest recorded in this time. Other areas that received over 70mm of rainfall include Mumbra, Kopar Khairane, Kandivalu, Ghansoli, Mohane, Panvel, Dahisar, Malwani, Naupada and Versova.

“The southwest monsoon has come in two days earlier than usual this year, as predicted by the meteorology department. There will be intense rains in Mumbai for at least a period of three to four days now, during which the total reading is quite likely to exceed 300mm, or even 350mm,” said a spokesperson with the IMD’s regional forecasting centre in Mumbai. However, independent meteorologists have forecast that Mumbai may even see 450 to 600mm of rainfall accumulated in some places during the next four days.

“Mumbai and areas are receiving widespread heavy rains. There are dense cloud formations visible above Mumbai and Thane at the moment, and in fact all along the coast. Heavy rainfall warnings have been issued for all west coast districts,” said KS Hosalikar, senior scientist at the IMD in Pune. Thunderstorms were also reported in various parts of the city.

Moderate to heavy rains are likely to continue till at least 3pm on Wednesday, after which they will decrease in intensity but continue until late evening, officials said.
