DENVER (AP) — Dry weather and winds forecast to gust to around 45 mph are expected to raise the risk of wildfires across the eastern half of Colorado as well as parts of Wyoming, Nebraska and Kansas.

The National Weather Service has posted red flag warnings Tuesday for areas including southeastern Wyoming, the Nebraska Panhandle and western Kansas. In Colorado, the warning area extends up and down the Front Range and south to Trinidad and east to the border as well as the San Luis Valley.

New fires can quickly spread out of control in the forecast conditions and the weather service is warning against any outdoor burning.
