In 24 hours ending at 8.30 am on Wednesday, the IMD’s Santacruz observatory recorded 193.6 mm of rain, categorised as very heavy rainfall.

Tuesday was the second consecutive day and fourth in the last six days of July, when very heavy rainfall was recorded in Mumbai. In the same period, the Colaba observatory, representative of south Mumbai, recorded 84 mm of rain, categorised as heavy rainfall.

On Wednesday, Mumbai and its suburbs recorded a few moderate spells (10-20 mm/hour) of rain. However, the rainfall was not incessant. In nine hours ending at 5.30 pm on Wednesday, the Santacruz observatory recorded 31.8 mm of rain, categorised as moderate.

Meanwhile, the Doppler radar – which surveys weather patterns and forecasts – situated at Colaba continued to remain suspended on Wednesday. The radar installed in 2010 at the Regional Meteorological Centre in Colaba has seen frequent breakdowns in the last four years.

A day before Cyclone Taukate lashed Mumbai’s coast last May, the radar was down. It was also down a day before Cyclone Nisarga brushed past Mumbai on June 2, 2020. During June and July 2019, when the city witnessed extremely heavy rain, the radar remained dysfunctional on both days due to technical difficulties. It also did not work on December 4, 2017, when Cyclone Ockhi brushed past the Mumbai coast.

Doppler radar, which can carry out weather surveillance up to 450-500 km radius from its location, is crucial for gauging the intensity of rainfall and impact area in real-time.
