YAKIMA, Wash. -- Department of Transportation officials say up to 19 inches of new snow could fall on Snoqualmie Pass between Wednesday afternoon and Thursday morning.
Only four inches of snow fell Tuesday night and crews are using the break to stock up on more explosives for their avalanche control efforts. They used 300 pounds of explosives for controlled slides on Tuesday.
DOT officials say the rising temperatures significantly increase the chances for major avalanches. They estimate that 30 feet of snow has fallen on Snoqualmie Pass this winter, leaving a ten-foot snowpack.
