Heavy rains are expected over the central plains and the western coast on August 6 due to a low-pressure area, Ministry of Earth Sciences Secretary M Rajeevan said on Saturday.
Heavy rains are also expected over Mumbai, especially on August 6, he added.
Mr Rajeevan said a weather system over the Bay of Bengal will move across central India to Gujarat, which will bring into heavy rains.
