Mumbai rains to continue today as well
Deluge in June: Mumbai's history with monsoon this month
If only June is considered, Mumbai received the highest one-day rainfall on June 10, 1991 at 399mm. The next was on June 19, 2015, when 283.4mm of rainfall crippled the city. And, yesterday's was the third. Anything above 204.5mm of rain is classified as 'extreme'.
Why the rains
Offshore trough created from South Gujarat to Kerala coast
IMD officials said the weather condition that the city and its suburbs are facing now will persist for today.
An offshore trough created from South Gujarat to Kerala coast is responsible.
The cyclonic formation over North Konkan (including Mumbai) and South Gujarat has now moved north, and so rainfall will reduce in the next 24 hours, explained KS Hosalikar, Deputy DG, IMD (Western Region).
