Weather Hazards
Heavy rain and high winds are expected today. The National Weather Service has issued a High Wind Advisory for locations above 3500 feet from 7 am this morning until 10 pm tonight, a copy of which has been posted below.
A strong cold front is expected to push through the region early Sunday, possibly bringing a light accumulation of snow, sleet, and freezing rain to the mountains. Gusty northwest winds will bring rapidly falling temperatures. A flash freeze is possible, which could result in poor road conditions in some areas. The gusty winds will continue through at least Sunday night. A few downed trees and powerlines are possible. Low temperatures will be in the single digits and teens Monday morning. These temperatures, along with the brisk winds, could support wind chills as cold as 10 degrees below zero at high elevations. Anyone expecting to be outdoors Monday morning will need to take precautions to protect exposed skin from these bitterly cold conditions.
