Powerful winds kicking up dust across the Plains contributed to multiple fatal crashes and sparked rapidly spreading wildfires on Tuesday as dry grasses fueled fast-moving flames.

Heavy winds created dangerous "brown out" conditions along Interstate 25 near Pueblo, Colo., on Tuesday morning, with a massive multi-vehicle crash happening amid low to near-zero visibility. The Colorado State Patrol responded around 10:02 a.m. MST to the crash on southbound I-25 at milepost 92, just south of Pueblo Boulevard. Preliminary findings indicate more than 30 vehicles were involved, including six semis.

Authorities have confirmed four fatalities, and 29 people were transported to hospitals, though the extent of their injuries remains unknown.

Both directions of I-25 were closed in the area -- northbound at milepost 93 and southbound at milepost 94 -- as the Colorado State Patrol Vehicular Crimes Unit continues its investigation.
