The National Weather Service in Wichita has issued a Flood Warning for the Arkansas River in Cowley and Sumner counties until 11:08PM tomorrow night [Wednesday]. Cowley County Emergency Management warns that minor flooding is forecast for Arkansas City, where the Arkansas River is expected to crest at 12 1/2 feet by late tonight. The river is expected to drop below flood stage by Wednesday afternoon. The Walnut River is also expected to rise to around 11 feet later today, but that river will remain well below the 18-foot flood stage. Emergency officials remind you not to drive into flooded areas or try to drive around barricades. They say shallow flowing water can wash a vehicle from the roadway very quickly.
