Snow closes North Cascades HighwayPosted by DaveH at November 19, 2012 03:30 PM
The North Cascades Highway closed at noon Monday, Nov. 19, after the mountains got an expected blast of snow.
About an inch of snow per hour was falling along the winding scenic highway in the early morning hours of Monday, leading crews to think it would shut down sometime in the evening, said state Department of Transporation spokesman Dustin Terpening.
But by 10 a.m., the flurries picked up the pace, dumping 4 ½ inches on the highway in 90 minutes. Three avalanches were reported along the Highway 20 route.
Once this storm passes through, crews will determine if it's safe enough to reopen, Terpening said. On average, winter weather closes the highway for about half of each year.
Terpening guffawed when asked if the highway might reopen for Thanksgiving travelers.
“With the weather, you never know,” he said.
