While the whole of Maharashtra is already reeling under heavy to very heavy rainfall for the past 3-4 days, the Indian Meteorological Department has issued a fresh red category warning of extremely heavy rainfall at isolated places in Pune and Satara districts.<br />''<br />''The forecast also predicted heavy rainfall at isolated places in Mumbai, Raigad, and Palghar. Major dams in the state, Koyna dam is already 86 per cent full, over 50,000 cusecs of water has been released in downstream Koyna river.<br />''<br />''Following incessant rains, 94 check dams on Panchganga river in Kolhapur district in western Maharashtra are submerged under water while Krishna river at Sangli is flowing close to the danger mark. Over 7000 cusecs of water has been released from Radhanagari dam in Kolhapur district so far. The water has entered nearby villages flooding roads. At Sangli, residential areas around Krishna river banks have been evacuated.<br />''<br />''The Parlkota river in Vidarbha's Gadchiroli district is flooded, cutting around 100 villages from the mainland. Several parts of Northern Maharashtra too, like Nanded and Dhule are facing water logging and traffic disruptions. Since most dams across the state have received good rainfall in catchment areas, the average water level at all dams has gone up considerably. <br />
