SIDNEY - Wildfires burning throughout the American West are forcing evacuations as crews deal with more hot, windy and dry conditions. Smoke from those wildfires have reached southeast Wyoming and the Nebraska Panhandle. 

The National Weather Service announced an Air Quality Alert for southeast Wyoming until 9 p.m. on Monday.

Smoke from Arizona wildfires is degrading the air quality across portions of southeast Wyoming. An Air Quality Alert is in effect on behalf of the Wyoming Department of Environmental Quality and the Wyoming Department of Health.

Additionally, a Special Weather Statement is in effect for portions of the Nebraska Panhandle for degraded air quality. These portions include Alliance, Scottsbluff, Kimball,  Potter, Dix, Bridgeport, Minatare, Bayard, and Sidney.

Sensitive groups should avoid excessive physical exertion and minimize time outdoors.

Spokesman for the Wyoming Department of Air Quality Keith Guille said, "Be aware of the air quality, especially groups who have lung issues, asthma, or the elderly."

Residents were ordered to flee remote homes near a wildfire in the mountains northeast of Los Angeles. 

In Arizona, firefighters are battling a wildfire on the northern outskirts of Flagstaff that has forced evacuations in the same area as another springtime blaze. 

Firefighters in New Mexico are battling some of the nation's largest blazes in tinder dry forests. Federal officials say the number of acres burned nationwide so far this year is more than double the 10-year average.
