PORTLAND -- Heavy snow continued to fall in the Cascades and resorts were expecting to get another foot of snow by Saturday, prompting the Oregon Dept. of Transportation to require chains on mountain passes.

Drivers were required to chain up on U.S. Highway 26, U.S. 20, OR 58 and OR 138, ODOT announced Friday afternoon. Officials also warned drivers to leave plenty of room for snow plows and not to pass them on the right.

Highway 35 was closed in both directions at milepost 65, west of Mt. Hood Meadows, after a multi-vehicle crash Friday afternoon in snowy conditions.

Evening snow showers may develop as low as 1, 500 feet, KGW Meteorologist Rod Hill said Friday evening. Look for improving road conditions Saturday afternoon as temperatures warm.

Scattered showers in Portland were expected to end by Saturday morning, but city officials warned drivers to be aware of black ice and frost throughout the area all weekend long.

The winter storm caused some problems near area waterways, but was not expected to bring significant damage.

Oxbow Regional Park along the Sandy River was closed until at least Saturday due to high water conditions and the Clackamas River crested at about 6 inches above flood stage Friday morning.
