Scattered snow showers are diminishing in the Rogue Valley, but emergency and road maintenance crews are keeping busy.

The National Weather Service has lifted winter storm warnings and advisories across Southern Oregon, as of 10 a.m.

Jackson County Fire District No. 5 responded to numerous weather-related crashes on Interstate 5 at the south end of the county. Mile 15 near Ashland was particularly treacherous with multiple crashes there, fire district officials said. A roll-over was reported near the Talent interchange.

City streets in Ashland were slippery with ice and snow. City employees are working to clear main arterial streets, such as Siskiyou Boulevard, Ashland Street and Main Street. Peterson expects those streets to be cleared of snow by about 11 a.m., depending on weather conditions.

Multiple accidents were also reported on Highway 238, which was glazed with ice in many areas.

Chains or traction tires are required over Siskiyou Summit and on Highway 62 approaching Crater Lake. Vehicles that are towing or have a gross vehicle weight of more than 10,000 pounds must use chains on I-5 in the Canyonville area and on Highway 140.

Drivers must carry chains and be prepared for winter driving.

Although snow showers are clearing out, the clear skies and an Arctic air mass moving in behind the storm front will bring colder temperatures throughout the day.

Expecting extremely cold weather along with potentially dangerous driving conditions, Ashland School District has cancelled Wednesday’s classes. Temperatures are forecast to not rise above 20 degrees all day, with 14 degrees forecast for bus pick-up times, school officials said.
