While the coastal districts are likely to receive heavy rains, the interior places in southern West Bengal are likely to get thunderstorms with lightning and gusty wind, the Met said.
A well-marked low pressure in northwest Bay of Bengal, which is likely to concentrate into a depression by Tuesday, is likely to bring in its wake heavy rain, with the intensity being higher in the coastal districts of the state till Thursday, the Met said.
