CHARLESTON, S.C.: Much of the US southeast was under water Saturday, deluged by rains from Hurricane Joaquin, with forecasters predicting more historic flooding in coming days for the already waterlogged region. Joaquin, a powerful Category 4 storm, brought record-setting rain to many southeastern US states after devastating parts the Bahamas and threatening to do much the same to Bermuda. News reports have blamed Joaquin for four deaths in the United States since Thursday. CNN reported that a falling tree in North Carolina killed one person. Three others died in weather-related accidents in South Carolina, it said. Meanwhile, the Bahamas, a low-lying archipelago, has huge areas where homes were destroyed and residents left without power or phone service after the Atlantic storm tore past.
