Cyclone Vayu, which developed from a deep depression off the coast of Lakshadweep on late Monday night, is now heading towards Saurashtra in Gujarat and is expected to intensify into a "very severe storm" by Tuesday night or Wednesday morning.

The India Meteorological Department has issued a warning of heavy rains and high winds at a speed of over 110 kilometres on June 13 and 14 in coastal areas of Saurashtra and Kutch.
"The system now is seen as a depression over the Southeast and East Central Arabian Sea and is centered at 11.2°N and 71°E, around 800 km South-Southwest of Mumbai", according to skymetweather.com.

It said heavy rains were very likely at isolated places in Porbandar, Jamnagar, Dwarka and Kutch on June 14.
