Warm weather starting today is expected to trigger renewed runoff from the higher elevations of the Rockies, sending the Pend Oreille River above flood stage next week, forecasters said Thursday. Because of flooding problems downstream from Newport, Washington, in recent years, the federal government announced Thursday that it is lowering the threshold flow for minor flooding on the Pend Oreille from 100,000 to 95,000 cubic feet per second. The mean flow in 2013 was 24,590 cfs.
