SIGNS HAVE BEEN POSTED ALONG SEVERAL ACCESS AREAS ALONG THE  RIVER.

THE WEATHER PATTERN:

An Upper Level Low Pressure Trough (“U” shape ) is moving away from us as weak High Pressure tries to replace it. The graphics for days 1-3  show no frontal  systems that moving into or through Oregon, but a cold front will be to our northwest Sunday. The graphics for days 3-7     Monday through Friday show a cold front that will push into the Pacific Northwest between Monday and Tuesday.
