Due to the forecast of very heavy rains in and around Mumbai and advance of Southwest monsoon causing tidal waves, there is the likelihood of inundation in some of the heavy rainfall affected urban areas of Mumbai City. Rivers having a source in the Western Ghats and flowing into the Arabian Sea may witness flash floods in association with the forecasted rainfall. Since most of the rivers are dry, necessary precautions to control the activities along the river bed may be taken as flow may increase suddenly drowning men and materials.

River Damanganga and its tributaries are expected to rise in Nasik district of Maharashtra, Valsad district of Gujarat and Daman district in Daman and Diu Union Territory. Since most of the rivers are dry, necessary precautions to control the activities along the river bed may be taken as flow may increase suddenly drowning men and materials.

River Godavari is likely to rise in Upstream reaches in the district of Nasik, Ahmednagar and Aurangabad district. Since almost all the dams are at a very low level, this rain may give inflows into various upstream reservoirs. River Krishna and its tributaries are likely to rise in upstream districts of Satara, Sangli, Kolhapur, Pune, Sholapur in Maharashtra as well as in Bagalkote, Vijayapura and Kalaburagi districts on Krishna and in Chikmagaluru, Shivamogga and Bellari districts on river Tungabhadra in Karnataka. Since almost all the dams are at a very low level, this rain may give inflows into various upstream reservoirs.

Rivers flowing West into the Arabian Sea south of Tapi in Maharashtra, Goa, and Karnataka are also likely to rise and inundate areas in Raigad, Thane, Ratnagiri and Sindhudurg districts of Maharashtra and in Uttara Kannada, Udupi and Dakshina Kannada districts in Karnataka. Traffic along the old road and rail bridges in Konkan Railway along these river reaches have to be regulated accordingly.

River Cauvery and its tributaries in upstream reaches in Kodagu, Chikmagalur, Hassan and Mysuru districts of Karnataka and Wynad district of Kerala are likely to rise in association with the forecasted rainfall.

However, as the dams in the basins have sufficient storage and hence the expected rainfall may give some inflows into these reservoirs depending on the severity of the rainfall.
