OMAHA, Neb. -- The remnants of Tropical Storm Isaac could bring welcome rain to some states in the Mississippi River valley this week, but experts say it's unlikely to break the drought gripping the Midwest.
Along with the deluge of rain expected along the Gulf Coast when Isaac makes landfall, the National Weather Service predicts 2 to 6 inches of rain will fall in eastern Arkansas, southeast Missouri and southern Illinois.
Those areas are among those hard hit by the drought that stretches from the West Coast east into Kentucky and Ohio, with pockets in Georgia and Alabama. The rain that falls inland likely will ease but not eliminate drought, because those areas are so dry, said Mark Svoboda, a climatologist with the National Drought Mitigation Center.
Arkansas rancher Don Rodgers said his area is short 17 inches of rain this year. He said even a couple of inches from Isaac would make a significant difference because he would have water for his cattle and might be able to grow some forage for this winter.
"I'm very sorry for the people in the path of this hurricane. I'm just praying we can get some of the benefit from it up here," said Rodgers, who has cattle in Crawford County, a rural area near the Oklahoma border.
Heavy rains, especially if it pushes into the Ohio Valley, would provide some relief for the low-water conditions that have hampered Mississippi River traffic for weeks, said National Weather Service hydrologist Marty Pope.
"If that happens, it would help us out quite a bit," Pope said.
Pope said any rise in the river would help clear clogged shipping channels, which have caused temporary closures in recent weeks. The low levels have prompted companies to reduce loads on barges carrying goods ranging from grain to gasoline, which can mean big losses for shippers.
Isaac has been gaining strength and could become a Category I hurricane before its expected landfall Tuesday or Wednesday. The storm's path may change before it reaches land, but the drought is so widespread that the rain is certain to be welcomed by those in any area that get it.
