The U.S. Army Corps of Engineers is issuing a small craft advisory for the McClellan-Kerr Arkansas River Navigation System in Arkansas. Heavy rain in Oklahoma and western Arkansas over the last two days has resulted in Arkansas River flows exceeding 70,000 cubic feet per second. A crest of 150,000 to 200,000 c.f.s is forecasted from Van Buren to Ozark and a crest of 250,000 to 300,000 c.f.s is forecasted to progress downstream from Dardanelle to Wilbur D. Mills Dam over the next week.
