KOIN 6 Meteorologist Kristen Van Dyke said heavier rain sets in during the evening hours of Wednesday.

Temperatures will be cold enough for a wintry mix to develop east of Multnomah Falls on Wednesday night, and 4-6 inches of snow and sleet will be possible.

ODOT Travel Alerts

Strong easterly winds with speeds of 50 mph will push through the Gorge, making travel treacherous along I-84.

There is also potential for freezing rain and icy conditions in a 24-hour period beginning late Wednesday along I-84 in the Columbia River Gorge, the National Weather Service said.

Hazardous driving conditions are possible from 10 p.m Wednesday until 10 p.m. Thursday.

Thursday will be another wet day from the coast through the Willamette Valley with little break from the rain or mountain snow.

Mountain resorts are expected to get another 1-2 inches of snow on Thursday. There will be a chance for a quick change-over to rain in the mountains late Thursday as snow levels rise.

KOIN Weather Alerts

By Friday, KOIN 6 Chief Meteorologist Kristin Van Dyke is anticipating 1-3 inches of rain in the valley and 3-7 inches along the Coastal Range and Cascade Foothills.

There’s potential for more flooding and landslides with this incoming system, and it all depends on where the heaviest rain sets up.

Near Diamond Lake

Crews from both ODOT and Pacific Power worked to remove more than 100 trees that fell onto powerlines and Oregon 138 East, blocking the highway. Trees are still falling, and ODOT officials said there is no estimate on when the highway will be open.

People who chose to say at the Diamond Lake Resort despite the oncoming storm were escorted by ODOT crews toward Roseburg.

Elsewhere around the state, the Associated Press reports:

Crater Lake rim closed to vehicles after heavy snowfall

Oregon’s Crater Lake rim is closed to vehicle traffic after winter storms dropped heavy snow and knocked down trees on near the park.

The Herald and News reports that a news release from park spokeswoman Heidi Barker says the visitor center is still open and the rim can still be accessed by skis or snow shoes.

Three days of storms dropped 43 inches of snow around the park, bringing the snowpack to 72 inches.

Barker says it is one of the largest snow storms the park has seen, although the amount of snow is not abnormal.

She says 69 storms since 1932 have resulted in bigger three-day snowfall accumulations than the current storm. A record 75 inches accumulated in three days in February 1971.

Snowfall brings hope to drought-stricken eastern Oregon

A snowstorm that swept across drought-stricken northeastern Oregon is expected to help replenish the region’s aquifers and reservoirs.

The Baker City Herald reports that the weekend storm left nearly two feet of snow in the higher peaks of the Elkhorns and Wallowas. Several inches of heavy, wet snow also fell at lower elevation and should help alleviate the drought.

Jerry Franke of the Burnt River Irrigation District says the weather is encouraging, but it’s still early in the season.

Last year, wintry weather arrived early but the rest of the season was drier and warmer than average.

But as of Monday morning, the water content in the snow was higher than it was at the same time last year.
