Red flag warnings cover parts of Colorado, Nebraska and Wyoming on June 12: wind gusts up to 72 km/h and humidity as low as 8% create conditions where any spark can start a wildfire.
The warnings include the Pine Ridge and Nebraska National Forest areas, the Eastern Panhandle, southwest Colorado, the Gunnison Basin and the Upper Arkansas River Valley.
Forecasters expect winds of 30–50 km/h with gusts to 72 km/h and relative humidity dropping to 8–15 percent. In such conditions fires catch and spread rapidly, and containment becomes extremely difficult.
A fire weather watch extends the danger into Saturday, June 13, for Fremont, Lake and Chaffee counties in Colorado.
