Torrential rains wreaked havoc in the megapolis today, throwing normal life in utter chaos. The city recorded a massive 65 mm of precipitation in just three hours.
Mr Mallick issued an advisory in the evening after discussing the situation with the higher authorities.
The advisory stated that if heavy rains persisted tomorrow, the staff may stay home. However, emergency services will continue. Those who have easy access to office may report for duty, it added.
Besides the metropolis, adjoining Navi Mumbai and Thane were lashed by incessant downpour since last night, delaying suburban train services and leaving vehicles crawling through waterlogged roads in the low-lying areas.
