Severe cyclonic storm Nisarga - the second to strike India in two weeks - made landfall on the Maharashtra coast near Alibaugh at around 1 pm. The storm is expected to weaken into a cyclone in a few hours. With wind speeds slowing down, coronavirus-hit Mumbai may have escaped the worst of the tropical storm. No damage has been reported from the financial capital where movement of people is restricted in public places like beaches, parks and promenades along the coastline till tomorrow afternoon. Flight operations have been suspended at the city's Chhatrapati Shivaji Maharaj International Airport till 7 pm. Besides Maharashtra, Gujarat, Daman and Diu, and Dadra and Nagar Haveli were put on high alert due to the cyclone that developed over a low pressure area over the Arabian Sea.
