A red flag warning has been issued for most of Natrona and Converse Counties, as well as most of southeast Wyoming, meaning fire danger in the area will remain high through Tuesday evening.

The National Weather Service in Riverton says low humidities and strong, gusty winds will create erratic fire behavior and new fire starts.

Conditions are expected to improve Monday night, but will become critical again Tuesday afternoon. The warning remains in effect from 12 p.m. Monday through 7 p.m. Tuesday.

In the Casper area, humidity is expected to be as low as 12 percent on Monday, and as low as 10 percent on Tuesday.

Southwest winds of 10-20 mph with gusts up to 35 mph are expected, with the strongest winds predicted for Tuesday afternoon.

The red flag warning applies to most of Natrona, Converse and Platte Counties, as well as parts of Carbon and Albany Counties. The warning covers all of Laramie, Goshen and Niobrara Counties.
