In a special bulletin, the India Meterological Department (IMD) said that besides these areas, north-central Maharashtra and south Gujarat were also likely to experience heavy to very heavy rain in the next 48 hours.
"The weather conditions are a result of the monsoon depressions that had formed over the Odisha coast, which moved westwards inland," V.K. Rajeev Nair, director, IMD Mumbai, told IANS.
The depressions weakened into a well-marked low pressure area by Thursday as a result of which Vidarbha in east Maharashtra and other areas are experiencing heavy and very heavy rainfall since the past two-three days, claiming at least 107 lives so far, the met official said.
Under the influence of this low pressure area which is taking a west north-westerly course, north Maharashtra, north coastal areas and south Gujarat could experience heavy to very heavy rains.
