Rising river water levels due to the landfall of cyclone Yaas have inundated large parts of West Bengal's coastal districts of Purba Medinipur and South 24 Parganas on Wednesday, as sea waves were seen touching coconut tree-tops and cars floating in floodwaters.

The seaside towns of Digha and Mandarmoni in Purba Medinipur and Fraserganj and Gosaba in South 24 Parganas were among the areas affected by a storm surge of more than 2 metres above the astronomical tide level.
