EUGENE, Ore. - Forecasters expect freezing rain to increase throughout the day, with up an inch of ice accumulating on roads, trees, power lines and other surfaces in the southern Willamette Valley.
Freezing rain and falling trees closed Highway 99 north of Cottage Grove from mile 12 to mile 14 on Saturday morning. A power outage in the area closed services at Interstate 5 rest areas there.
Oregon DOT urges motorists in the Willamette Valley, Coast, Coast Range and Cascade foothills to stay off area roads for one more day as crews work on roads.
The Ice Storm Warning issued early Saturday remains in effect until 10 p.m., the National Weather Service said.
Forecasters had predicted snow turning to ice. But earlier forecasts saw freezing rain giving way to rain by Saturday afternoon.
Then it was evening.
Now the timing of a thaw is more uncertain.
The temperature is not forecast to get above freezing until Sunday, when daytime highs should hit 47 F. Temperatures will stay above freezing Sunday into Monday, when the daytime forecast high is 53.
