ESFSEW A storm system will bring in heavy rainfall at times over the Olympic Mountains Wednesday and Thursday. Total precipitation amounts will range from 1 to 3 inches, though rainfall amounts will be highly dependent on the convective nature of this storm system and where heavier showers set up. Snow levels will stay above 8000 feet on Wednesday before falling to 3500 feet on Thursday, increasing the potential for river flooding. River flooding remains possible and we will continue to monitor the potential for river flooding during this period.

ESFPDT Temperatures in the 60s and 70s Wednesday will increase snow melt of the mid and high elevation snow pack. This will be followed by mountain rain Wednesday through Friday. Saturated mountain soils will allow for efficient runoff and will increase water levels on mountain rivers, creeks and streams. The primary concern is the John Day River at Service Creek which is forecast to reach minor flood stage Friday morning through Saturday morning, peaking Friday afternoon. The Naches River at Cliffdell is currently in action stage and is forecast to peak Thursday night before slowly declining to below action stage

ESFLKN As high pressure builds across the Great Basin through the beginning of the week, near to record warm high temperatures are forecast. This will help to increase the melt rate of mid- and high-elevation snowpack, which will make it into area creeks and streams. Faster responding creeks that will need to be watched for higher flows include Martin Creek in Humboldt county, the Owyhee River, Bruneau River, and Salmon Falls Creek in Elko county. Though flooding is not expected at this time, water in area creeks and streams will be flowing strongly thru at least midweek. Residents and outdoor

ESFPIH Temperatures will continue to run well above average through Thursday, increasing low and mid elevation snowmelt and runoff. Standing water in typical low spots can be expected, and we'll also likely begin seeing the swelling of smaller creeks and tributaries that feed the larger streams and rivers. This may even push some streams and creeks above bankfull causing minor flooding and bank erosion due to the higher flows. The warm temperatures will peak Wednesday with afternoon highs reaching well into the 60s in most locations, and into the 70s in some lower valleys. These will be the warmest readings

This may even push some streams and creeks above bankfull causing minor flooding and bank erosion due to the higher flows. Temperatures will remain anomalously warm until a cold front passage Thursday. Even the overnight lows will stay above freezing through Thursday night, which will exacerbate snowmelt runoff.
