The National Weather Service is urging motorists to be cautious during their morning commutes because of dense freezing fog in the Rogue Valley.
Portions of Interstate 5, including corridors through Ashland, Medford, Rogue River and Grants Pass have limited visibility, which could drop to one-quarter mile through at least 9 a.m.
Motorists should watch out for potentially icy spots on the road, especially on overpasses. Allow extra travel time and space while braking.
Spots of ice have been reported on the Siskiyou Pass, Highway 66 and Highway 140, according to www.tripcheck.com.
In the surrounding hills, weather officials predict up to 2 inches of additional snowfall today, adding to Thursday night's snowfall of anywhere from 2 to 4 inches. As of this morning, Mt. Ashland had seen 3 inches of new snow.
Crater Lake, Crescent Lake, Diamond Lake and Howard Prairie should all receive additional accumulation, along with winds up to 15 mph. A winter weather advisory is in effect until 10 a.m., meaning periods of snow could cause travel difficulties.
As of 7:20 a.m., the NWS website showed Medford's temperature at around 30 degrees, breaking the city's 230-day streak of not hitting a freezing temperature.
