North Cascades Highway closed by heavy snow - NBC Right Now/KNDO/KNDU Tri-Cities, Yakima, WA |

WINTHROP, Wash. (AP) - The Washington Transportation Department closed the North Cascades Highway at noon Monday because of heavy snow and avalanche danger.

The department says there were three slides and more than 4 inches of snow within 90 minutes.

The department says the closure is temporary, but the section of Highway 20 over the north Cascades typically closes for the winter this time of year.
