Medford, Oregon – Travel across the high Cascades in southern Oregon could become hazardous overnight as snow begins falling by 11 p.m. Tuesday, with slick roads and reduced visibility impacting key mountain routes by the Wednesday morning commute.
According to the National Weather Service in Medford, a Winter Weather Advisory remains in effect through 5 a.m. Thursday for elevations above 4,000 feet across Klamath, Jackson, and Douglas counties. Snow totals of 4 to 12 inches are expected, with the heaviest accumulation focused around Crater Lake, Diamond Lake, and Crescent Lake. Winds could gust up to 45 mph over exposed terrain, increasing the risk of blowing snow and downed tree branches.
Conditions along Highway 58 at Willamette Pass and near Diamond Lake Junction on highways 230 and 138 may deteriorate quickly, especially during peak travel hours Wednesday morning and evening. Drivers could encounter chain requirements, delays, or temporary closures.
Officials urge travelers to slow down, carry emergency supplies, and check TripCheck or call 511 before heading out. Snow and wind impacts will persist through early Thursday, with additional advisories possible if conditions intensify.
