A low pressure area off Maharashtra coast is likely to bring rainfall over India`s western coast and north Maharashtra, and Gujarat starting from Wednesday while a low pressure over south Thailand is likely to emerge as a cyclonic storm over the east coast on December 4, the IMD said.

The already rain- and flood-battered eastern coast is set to witness more rainfall as a low pressure lay over south Thailand and neighbourhood on Tuesday and is likely to emerge into Andaman Sea by early Wednesday.
