Southern Oregon is in the midst of a wet weather pattern to start the week, and travelers should remain alert to rainfall-related hazards, especially through Friday. As of Monday, moderate to heavy rain has already soaked much of the region, causing slick roads, reduced visibility, and localized ponding in low-lying areas and along highways. Rivers and streams are running high, and although widespread flooding is not expected at this time, travelers are urged to use caution near creeks, underpasses, and rural roads where water may accumulate quickly.
Through Wednesday, rain will continue off and on across the Rogue Valley, Applegate, and Illinois Valley regions, with daytime highs hovering in the low 50s to upper 50s. Nighttime temperatures will stay cool but above freezing, in the upper 30s and low 40s. Patches of morning fog may add to driving concerns, especially near rivers and open fields. Travelers should plan extra time for morning commutes and be wary of reduced visibility, particularly along I-5 and Highway 199.
By Thursday, a stronger system will move in, renewing widespread rainfall and bringing gusty winds, especially in coastal areas like Brookings and Gold Beach. Inland areas including Medford, Grants Pass, and Roseburg can expect steady rain, and while snow levels will remain mostly above 4,500 feet, heavier bursts of precipitation could bring brief snow showers to higher elevation routes like Siskiyou Summit and portions of Highway 140. Those traveling through the mountains should be prepared for sudden changes in conditions and possible chain advisories if temperatures dip lower than forecasted.
Friday is expected to bring the heaviest rainfall of the week, and drivers should expect pooling water on roads, potential minor debris flows in burn scar areas, and longer commute times. Winds along the coast could create hazardous conditions for high-profile vehicles on Highway 101. Inland, wind gusts will be lighter but noticeable at times.
Relief arrives as the weekend approaches. Saturday will bring decreasing showers and more dry breaks, with partly sunny skies returning to most of the valleys and highs rising to near 60 degrees. Sunday looks to be the best travel day of the week, featuring mild temperatures, mostly sunny skies, and dry conditions perfect for outdoor plans or scenic drives.
However, anyone planning to travel over mountain passes or along coastal routes should stay up to date with the latest forecasts, as storm runoff and residual moisture could continue to impact rural and forest roads. Another potential system may begin moving in late Sunday or early next week, so travelers returning from weekend trips should remain alert for any weather updates.
Travelers should be especially cautious from now through Friday due to ongoing rainfall, and if possible, plan longer trips for the weekend when conditions are expected to improve significantly.
