Heavy rainfall has flooded India's tech hub Bangalore and disrupted normal life across the city Friday.
"Depression in the Bay of Bengal and formation of thick cloud owing to the southwest retreating monsoon triggered the downpour across the city and neighbourhood," a senior weather official told IANS here.
A record 132 mm of rainfall has been recorded in Bangalore since Thursday.
The heavy downpour lasted for over three hours starting from 7 p.m. and inundated low-laying areas in many suburbs, uprooted at least a dozen trees in some localities, and caused traffic snarls due to gridlock on the city's busy thoroughfares.
Thousands of office-goers returning home and people on shopping spree ahead of the 10-day Dussehra festival were caught off guard, as thundershowers intensified into downpour due to low pressure and strong winds.
"There was a forecast that moderate to heavy rain will lash the city and south interior region of the state in the next two days due to inclement weather," weather office director B. Puttana said.
