A massive dust storm was racing toward Chicago and the rest of northern Illinois, putting motorists and people with respiratory illnesses at risk, weather officials warned Friday evening.

A dust storm loomed over a residential suburb in the U.S. Midwestern state of Illinois on Friday (May 16), as authorities warned of a fast-moving wall of dust that engulfed northern Illinois and parts of neighboring Indiana and Chicago.

The Chicago area is once again looking at a stormy evening with the potential for some severe weather Friday night, and a rare dust storm warning was issued for much of the Chicago area as blowing dust is causing reduced visibility on several Interstate highways.
