Snow that reached down to the Rogue Valley floor closed multiple school districts Thursday.

Students in Medford, Phoenix-Talent, Central Point, Rogue River, Ashland and Eagle Point have a snow day. Southern Oregon University, St. Mary's School, Prospect Charter School, Grace Cascade Christian Schools, Logos and Jackson County Early Intervention are also closed, as is the Three Rivers School District in Grants Pass.

Rogue Community College is on a two-hour delay. The U.S. District Court will open at noon. Snow was still falling steadily in Medford at 8 a.m.

At 7:40 a.m., the city of Medford issued a notice saying East McAndrews Road was closed between Tamarack Drive and Hillcrest Road due to icy conditions. Between 6:15 and 7:15 a.m., emergency crews responded to six car crashes around Jackson County, according to dispatch records.

A winter storm warning remains in effect until 1 p.m., according to the National Weather Service. Accumulations of up to six inches are expected in the mountains, with up to three inches in the valley.

Drivers should expect winter driving conditions and consider delaying travel, especially over Interstate 5 mountain passes, until conditions moderate, according to the Oregon Department of Transportation. At 7:30 a.m., chains were still required for all vehicles — except 4x4s — on the Sexton, Smith and Stages passes between mileposts 66 and 80 on I-5.

"Travel along Interstate 5 between Grants Pass and Roseburg may be very difficult. Expect snow-packed roads and very low visibility at times," a Weather Service advisory said.

Rogue Valley Transportation District buses remained on schedule, with slight delays for Ashland and White City routes.
