The National Weather Service has issued red flag warnings across much of Colorado for Tuesday.

The warning starts as early as 11:00 a.m. over the eastern plains, while other parts of the state start slightly later. In addition to the plains, warnings will be in effect for the San Luis Valley and portions of southwest Colorado.

Wind out of the northwest is expected to gust between 30 and 40 miles per hour, with humidity falling as low as 10 to 20 percent, creating conditions favorable for the rapid spread of fires that do start. Temperatures will be in the 70s and 80s Tuesday.

Most of Nebraska, northwest Kansas, and northwest and central New Mexico will also be under warnings.

The warnings are currently set to expire at 8:00 p.m.
