Snoqualmie Pass still closed; new slide overnight
More than 300 cars wait to be escorted down from Snoqualmie Pass on Thursday. The cars and their passengers were stranded at the top when an avalanche closed I-90 Wednesday. State crews were working to stabilize the hillside to prevent further avalanches.
More easily noted in the Enhanced Infrared Satellite, the vortex over the North Atlantic leading to the Equator was interrupted and gives a break to the central continent of North America; through the movement of a Pacific front headed for the western seaboard.
The velocity of the approaching Pacific front is considerable and will deliver more significant weather issues to the northwest NA continent. The cold experienced by the ski resorts in the USA comes from the Canadian system which is primarily stationary at this point. The large volume snow however is due to heat transfer and the significant moisture carried with those to higher latitudes. Heat transfer systems are dependant on clouds. Clouds are water vapor and carry the heat in water's latent forms. Heat transfer systems are water dependant systems.

SNOQUALMIE PASS — Snoqualmie Pass remained closed this morning as another avalanche dumped snow near the summit and whiteout conditions were reported.
Over the past six days, nearly five feet of snow has fallen on the pass, said Erin Bogenschutz, spokeswoman for the state Department of Transportation.
She said there was no estimate when the pass might reopen, adding that it was the avalanche danger, not the snowfall, that is keeping it closed
The state had hoped to open the pass at 9 a.m. today.
According to the National Weather Service, from 12 to 16 inches of snow fell on the pass Thursday. The DOT said seven inches of snow between midnight and 6 a.m. today at the pass and another six to eight inches were forecast for today....
