As per the weather department’s classification, 15.6mm to 64.4mm of rainfall is considered ‘moderate’, 64.5mm to 115.5mm is ‘heavy’, 115.6mm to 204.4mm is ‘very heavy’ and more than 204.5mm is ‘extreme’.

The weather bureau on Saturday has predicted heavy to very heavy rain till Wednesday. After moderate to heavy showers over the weekend, warnings were escalated on Sunday for extremely heavy rain in isolated areas through the week. On Sunday, most parts of the city recorded continuous spells of heavy to very heavy rain, the weather bureau said.

The India Meteorological Department (IMD) forecast on Monday morning read: “Continuous rain with heavy to very heavy rain at a few places and extremely heavy rain at one or two places in the city and suburbs for the rest of Monday as well as Tuesday.”

“An upper air anti-cyclonic circulation (weather system) over the Arabian Sea, a similar weather system over the Bay of Bengal, and an offshore trough are allowing the monsoon current to be active over the north Konkan coast, including Mumbai. We expect heavy to very heavy rain, with isolated, extremely heavy spells over Mumbai and the surrounding areas till Wednesday, after which rainfall is expected to reduce slowly,” said Ajay Kumar, scientist, IMD, Mumbai. “This warning has been conveyed to the BEST, the BMC, railways and the state government.”
