Tropical Storm Debby is swirling over the coastal Carolinas, with wide bands of rain falling over saturated areas and swelling inland waterways. The storm's center was lingering east of Savannah, Georgia after stirring up tornadoes and submerging streets in waist-high floodwaters. The latest forecast says Debby could restrengthen over the ocean before its center moves inland again in South Carolina by Thursday. After that it should move relatively slowly across southern states, with staggering rainfall totals possible in some areas. Debby first hit the U.S. mainland on Florida's Gulf Coast early Monday as a hurricane. At least six people have died.
