Smoke From Ariz. Wildfire Travels 1,000 Miles

DENVER, Ariz. --

Smoke from the Arizona wildfire has spread as far away as 1,000 miles from the blaze.

Kyle Fredin, a meteorologist for the National Weather Service in Denver, said Monday that a ridge of high pressure was carrying the smoke as far away as central Iowa.

He said the smoke was also hitting eastern Colorado -- where it obscured the view of the mountains from downtown Denver -- as well as New Mexico, Nebraska and Kansas.

State health officials have issued a smoke health advisory through noon Tuesday.

They said if visibility is less than five miles or the smoke becomes thick, it may have reached unhealthy levels.

People with heart disease, respiratory illnesses and the young and elderly are encouraged to stay inside.
