Days of unrelenting heavy rain and storms that killed at least 18 people worsened flooding as some rivers rose to near-record levels Monday and inundated towns across an already saturated U.S. South and parts of the Midwest. Cities ordered evacuations and rescue crews in inflatable boats checked on residents in Kentucky and Tennessee, while utilities shut off power and gas in a region stretching from Texas to Ohio. “I think everybody was shocked at how quick (the river) actually did come up,” said salon owner Jessica Tuggle, who was watching Monday as murky brown water approached her business in Frankfort, Kentucky, the state capital along the swollen Kentucky River.
