High tides and strong, onshore winds amplify effects.
65 Severe flooding is expected in the delta area, particularly US Highway 101 in the vicinity of Requa Road, the access road to Klamath Glen, and secondary roads. The forecast level is within 0.5 feet of top of levee. Any persons living or working in areas protected by the levee should take appropriate action and move to higher ground. High tides and strong onshore winds will amplify flooding effects.
64 Severe flooding is the delta area is likely, particularly US Highway 101 in the vicinity of Requa Road, the access road to Klamath Glen, and secondary roads.
