Mumbai: The city and suburbs on Friday received the maximum rains this monsoon to date.
Colaba weather observatory, which covers south Mumbai, recorded 157 millimetres (mm) of rainfall between 8:30 and 11:30 am on Friday morning after torrential downpour inundated several low-lying areas in the city.
India Meteorological Department (IMD) classifies 20-30 mm rain per hour as an intense spell; 30-50 mm per hour as a very intense spell; 50-100 mm per hour as an extremely intense spell; and over 100 mm per hour as a cloud burst.
Friday’s showers in south Mumbai fell in the “very intense spell” category.
Cuffe Parade topped the location-wise rainfall data received from south Mumbai at 105 mm; followed by the area in and around the Chhatrapati Shivaji Maharaj Terminus (CSMT) (97mm), Worli (85 mm), Malabar Hill (81 mm), Haji Ali (76 mm), Matunga (65 mm), Sewri and Parel (64 mm), and Dharavi (62 mm).
The intensity of the rains lessened around 12.30pm onwards.

Earlier, KS Hosalikar, deputy director, western region, IMD, had predicted intense rainfall in Mumbai and its adjoining areas on Friday and Saturday.
“Isolated areas in south and central Mumbai have recorded approximately 70 mm overnight rainfall. Radar images are indicating active monsoon conditions over Mumbai and its surrounding areas. Mumbai and its suburbs may receive up to 50 mm rain per hour. The entire Konkan coast, including Mumbai, will receive heavy incessant rains for the next 48 hours. People are advised to avoid travelling,” he said.
IMD has issued an orange alert — heavy to very heavy rain — for Friday and Saturday, but the intensity is likely to lessen from Sunday.
It has also warned of waterlogging in several low-lying areas of the city, temporary disruption of civic services such as water and electricity, traffic snarls, the likelihood of collapse of old buildings, and uprooting of trees.
IMD has urged proper regulation of city traffic and restricted movement for Mumbaikars in waterlogged areas.
IMD classifies light rain between 2.5 and 7.5 mm; moderate rain (7.6-35.5 mm); heavy rain (35.6-64.4 mm); and extremely heavy rain (64.5-124.4 mm).
