Drivers should expect potentially hazardous driving conditions in higher elevations of northern Arizona as a late-season winter storm is expected to bring rain and snow to parts of the state through Thursday morning, according to the Arizona Department of Transportation.

With snow continuing to fall, putting off travel is the safest option

Multiple stretches of Arizona’s highways remained closed Thursday afternoon, Feb. 21, due to a powerful winter storm whose fury continues across much of the state.

With the heavy weather expected to last into Friday, the safest option at present is for drivers to delay travel to and through higher elevations until the Arizona Department of Transportation’s plows have cleared highways of snow and ice. Motorists in lower elevations may see some snow along with considerable rainfall.


The recent flows from summer monsoon rains have eroded embankments at a number of locations within Nogales Wash, exposing and threatening critical infrastructure and property. The U.S. Army Corps of Engineers (USACOE) is working to stabilize banks along the Nogales Wash.

The Arizona Department of Transportation delivered 70, 20-foot sections of concrete barrier to assist in the erosion mitigation along the banks of the Nogales Wash.

Work on the Frye Fire Burned Area Response (BAER) continues at the Wet Canyon area along the Swift Trail (Highway 366).  Road crew personnel and equipment from Arizona Department of Transportation (ADOT) and the Coronado National Forest have been working at this site for four days removing logs and other woody debris from the Wet Canyon stream channel in an effort to keep storm flows from damaging the critical highway bridge structure at this location. 

This past weekend road crews from the Arizona Department of Transportation (ADOT) and the Coronado National Forest worked together to remove debris from the Wet Canyon Recreation Site on the Swift Trail (State Highway 366). This past week several heavy storms moved a significant amount of woody debris and rock down Wet Canyon, effectively blocking flow under a historic CCC bridge and threatening the structure of the main road bridge. By Sunday evening enough debris had been removed to return the water flow to the original channel under the old bridge.

US 180 remains closed in both directions northwest of Flagstaff because of the Boundary Fire, according to the Arizona Department of Transportation. The closure is between mileposts 236 and 248.

The closure blocks the most direct route between Flagstaff and Valle. Drivers can use Interstate 40 and State Route 64 as alternate routes between those communities.

There is no estimated time to reopen US 180.
