The IMD has forecast rainfall in Saurashtra and Gujarat on Wednesday and Thursday

Severe cyclone 'Maha' is forecast to re-curve and take U-turn out in the East-Central Arabian Sea and head towards the Gujarat coast between Diu and Dwarka around midnight on November 6.

The India Meteorological Department (IMD) located the severe cyclone about 550 km West-South-West of Veraval (Gujarat) and 580 km West-South-West of Diu on Sunday morning.

It is very likely to intensify into a very severe cyclone later in the evening, and continue to move in a West-North-West direction till Monday, before beginning to re-curve (i.e. make a U-turn) East-North-East.

This would orient it towards the Gujarat coast, but the very severe cyclone would also start weakening gradually from November 5 (Monday) onwards, as it encounters cooler waters near the coast. Cooler waters interfere with the process of evaporation and convection (cloud-building around the storm), the fuel for the cyclone system, compromising its strength and intensity.

"Severe cyclone Maha should cross the Gujarat coast between Diu and Dwarka, and pack maximum sustained wind speeds of 100-110 km/hr gusting to 120 km/hr," the IMD said.

It has has forecast light to moderate rainfall at most places with heavy to very heavy rainfall at a few places over Saurashtra and Gujarat on Wednesday and Thursday. Light to moderate rainfall is also forecast at most places with isolated heavy rainfall very likely over North Madhya Maharashtra and North Konkan, including Mumbai on these days.

The IMD's forecast track and intensity for severe cyclone Maha is as follows:
