The cyclonic storm could make landfall near the border of Gujarat and Maharashtra around Vapi on Wednesday.

The IMD has four colour-coded warnings as per the intensity of any weather system — green, yellow, orange and red.

The IMD has issued an orange-colour coded warning to Kerala, coastal Karnataka, Goa and coastal Maharashtra for June 1. The same warning applies to coastal Maharashtra and Goa for June 2.

For June 3, a red-coloured coded warning has been issued to coastal Maharashtra and Goa and an orange coloured warning to Gujarat.

The red-coloured warning has been issued to coastal Maharashtra, Goa and the entire state of Gujarat for June 4, Sathi Devi, the head of the National Weather Forecasting Centre, said.

"An intense rainfall activity is expected due to the weather system," Devi added.

The India Meteorological Department on Sunday issued a red-colour coded warning to coastal Maharashtra and Gujarat for June 4 in view of a cyclonic storm in the Arabian Sea.

"A low pressure is currently over east central Arabian Sea and the Lakshadweep Islands. It is likely to intensify into a depression in the next 12 hours and a cyclonic circulation in the next 24 hours," the Cyclone Warning Division of the IMD said.

A low pressure area is the first stage of any cyclone.

"It is very likely to move nearly northwards initially till June 2 and then recurve north-northeastwards and reach near north Maharashtra and south Gujarat coasts around June 3," it added.

Once the storm intensifies into a cyclone, it will be named Nisarga, as per the new list of cyclone names approved by the World Meteorological Organisation. It will be the second cyclone over North Indian Ocean this season after Amphan.
