A second round of heavy rain is expected along the coast and into Douglas and western Josephine Counties Tuesday through Wednesday. River and streams which are already running high will see additional rises. Minor flooding is forecast for the Coquille River at Coquille Monday into Tuesday morning with additional chances for minor flooding mid week. Ponding of water on roadways, isolated minor flooding in low lying areas and isolated rockfalls and mudslides will be possible.
Another front will bring strong, gusty winds to the area Wednesday, with strongest winds east of the Cascades. Driving could be difficult at times, especially for high profile vehicles. Be sure to secure loose objects on property to prevent items from being blown around.
An extended period of wave action is expected this weekend into early next week as a series of fronts with multiple swell trains passes through the region. Breaking waves of 20 to 30 ft will lead to an increased risk of beach erosion. Additionally, there will be a minor to moderate risk of sneaker waves as these swell trains build into the waters. Beaches will be hazardous places to be through Wednesday, so if you plan to venture to area beaches, take extra caution to avoid the surf zone and stay off jetties. Remember to never turn your back on the ocean!
A strong frontal system will bring significant winter impacts to the forecast area late Wednesday night through Friday morning. Most of the snowfall will be in the southern Oregon Cascades, especially from near highway 140 north. The heaviest snow is expected above 4500 feet elevation from Lake of the Woods northward. Moderate to major impacts are anticipated due to heavy snowfall.
