The National Weather Service has issued a flood warning for the Curry County Coast from Saturday evening through Monday morning.
Rain is forecast to fall for the next seven days.
Rainfall this weekend is expected to exceed 5 inches with up to 8 inches possible in the coastal ranges, and extensive run-off is likely due to saturated soils from the most recent rainfall. Rapid rises are expected on all major rivers, with possible flooding along smaller creeks and streams.
Additionally, flooding is possible in urban areas and pastures, as well as the threat of landslides, rock falls and debris flows, the weather service said.
People are encouraged to monitor forecasts as the weekend progresses, and those in flood-prone areas should be prepared to take action should it occur.
People, structures and roads located below steep slopes, in canyons and near the mouths of canyons may be at serious risk from rapidly moving landslides.
The Chetco River was flowing at 2,720 cubic feet per second (cfs) Thursday and 3,710 cfs Friday morning.
Additionally, a high surf advisory is in effect from 11 a.m. today (April 6) to early Sunday morning on the Southern Oregon Coast, with a large west swell arriving late Saturday morning and producing breakers of around 23 feet through Saturday night.
Impacts are likely to include sudden and unusually high beach run-up, which can take beachgoers by surprise, resulting in possible injury or drowning. Logs and other debris can become lifted and floated, increasing risk to those in or near the water.
