It was also down a day before Cyclone Nisarga brushed past Mumbai on June 2, 2020.

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.
