As the city is set to open up in phases after a two-month lockdown, it stares at an extremely heavy rain warning by the Indian Meteorological Department (IMD).

A red alert has been declared for Mumbai, Thane and Palghar with heavy rain and thunder-shower forecast for the week. It will be a result of the cyclonic storm forming in the Arabian Sea that is causing low pressure. A slight drizzle on Monday morning soothed the city after a long period of intense heat and humidity. Citizens should expect extremely heavy rain at isolated places in the next couple of days, the IMD said. "A low-pressure area over Southeast and adjoining East-Central Arabian Sea and has intensified into a depression. It is very likely to intensify into a deep depression and further intensify into a cyclonic storm. It is very likely to move nearly northwards till June 2 and then cross north Maharashtra and south Gujarat coasts between Harihareshwar (Raigad, Maharashtra) and Daman during the afternoon of June 3," the IMD stated.
