Crater Lake, Oregon – Travel through the southern Oregon Cascades could become nearly impossible within the next 48 hours as a major snowstorm targets mountain passes starting early Wednesday.
According to the National Weather Service in Medford, a Winter Storm Watch is in effect from late Tuesday night through Thursday afternoon for elevations above 3,000 feet, including Crater Lake, Diamond Lake, and routes near Toketee Falls and Union Creek. Snowfall totals of 10 to 20 inches are possible, with wind gusts up to 40 mph across exposed terrain.
Conditions are expected to rapidly deteriorate early Wednesday, especially along highways 62, 138, 140, 230, and 58, where heavy snow and blowing winds could reduce visibility and create impassable stretches. Mountain passes may see chain controls or closures during peak snowfall.
Areas surrounding Crater Lake and Diamond Lake will likely experience the heaviest snow, with drifting snow and limited visibility creating dangerous travel conditions through both the Wednesday morning and evening commutes.
Drivers are urged to prepare for winter driving conditions, carry chains, and monitor updates through Oregon DOT before traveling. Delaying non-essential trips through the Cascades is strongly advised.
The watch remains in effect through Thursday afternoon, with warnings likely as confidence in snowfall totals increases.
