A storm system that's dropping snow on the western half of the state will bring up to four inches of rain to the St. Louis area by Sunday.
But don't expect much in the way of flash flooding, says National Weather Service hydrologist Mark Fuchs.
"We're not necessarily expecting flash flooding in the classic sense - where you see a very quick rising water coming down the stream," Fuchs said. "But with that being said, there will be some roads in poor drainage areas that could go underwater."
The Coast Guard is assessing the environmental impact of roughly 300 gallons of crude oil it says spilled into the Mississippi River after more than a dozen barges briefly broke free near Alton, Ill.
The Coast Guard says a vessel hit an area where barges are docked on the river about 1 a.m. this morning, causing 14 to break away from their moorings. Those barges then hit another barge loading crude oil, which caused the spill of about seven barrels (300gallons) worth of oil.
