SNOQUALMIE PASS, Wash. -- Crews on Saturday made progress clearing debris, snow and standing water from the major highway pass through Washington's Cascade Range, with hopes of reopening it to traffic late at night.

However, the other two passes likely will remain closed into Sunday due to heavy snow.

Reopening Snoqualmie Pass on Interstate 90 would be a boost for travelers who have been unable to cross the mountains since Washington's three large passes became simultaneously closed early Friday afternoon. About 72 miles of Interstate 90 have been closed.

Avalanche control crews cleared snow and standing water from Snoqualmie Pass with a goal of reopening the road until midnight Saturday, said Meagan McFadden, spokeswoman for the state Department of Transportation.

White Pass and Stevens Pass likely will remain closed into Sunday.

Highway 2 over Stevens Pass was closed between Leavenworth and Deception Creek. Highway 12 over White Pass was closed between Coal Creek Drive to near Wildcat Road.

"It's a little too dangerous for their crews to be out at night, so once it gets dark, they're going to stop working and reevaluate the situation in the morning," McFadden said.

Highways in Eastern Washington were all open, after blowing snow forced the closure of a number of roads on Friday. Spokane County commissioners even declared a state of emergency Friday afternoon, closing all roads in the southern and western portions of the county due to high winds and blowing snow. Blowing snow also closed several highways in the Palouse area between Pullman and Spokane.

The forecast for Eastern Washington called for more snow on Sunday. The National Weather Service also issued a winter storm watch for the western slopes of the central and north Cascades for Saturday night and Sunday. So more snow or rain could be on the way.

Since Feb. 1, 86.5 inches of snow have fallen on Snoqualmie Pass, bringing the total this winter to 416 inches. The record for winter snowfall is 696 inches of snow in 1945-50.

"And we still have three months left, because we sometimes get snow still in May," McFadden said. "As more snow falls, we get a little closer to those record years."
