(Burns, OR) -- The flooding in Harney County could worsen this week. Over the weekend, flood waters started to recede, but the Silvies River is expected to rise again on Tuesday due to rain and warm temperatures melting the snowpack. A Flood Warning remains in effect through next Monday. Residents are being told to stay vigilant, even as some roads become passable again. Sandbag stations have reopened and the Burns sewer system remains impacted by excessive runoff.
