Denver, Colorado – A persistent dry pattern through March is increasing the risk of rapid wildfire spread along the I-70 corridor from eastern Colorado into central Kansas, with multiple wind events capable of driving flames across open rangeland in minutes. The threat is not confined to one outbreak but tied to repeated days of low humidity and gusty winds expected throughout the month.
According to the National Interagency Fire Center’s March 2026 outlook, significant wildland fire potential is projected to run above normal across portions of eastern Colorado and much of Kansas. Forecasters point to warmer-than-average temperatures and limited widespread precipitation as key drivers. Afternoon humidity levels may frequently fall between 15 and 25 percent, especially on sunny, breezy days.
The most vulnerable areas stretch from the Denver metro south toward Pueblo and east along I-70 toward communities such as Limon, Goodland and Hays. Additional concern extends along I-25, US-24, Highway 50 and US-83, where dormant grasses and drought-stressed vegetation provide receptive fuels.
When southwest wind gusts exceed 30 to 40 mph, fire spread rates can accelerate quickly, particularly in open terrain. Fire managers warn that even routine roadside sparks, dragging trailer chains or agricultural equipment could ignite fast-moving grassfires under these conditions.
Residents across the Colorado-Kansas region should avoid outdoor burning during windy periods, secure towing equipment and clear dry brush away from homes and barns. Elevated fire danger is expected to develop in waves through the end of March, and Red Flag Warnings may be issued on short notice when critical thresholds align.
