Chicago, Illinois – Outdoor sparks could turn into fast-moving fires within minutes across northern Illinois this afternoon as strong winds and extremely dry air combine to create volatile conditions.
According to the National Weather Service in Chicago/Romeoville, southwesterly winds gusting up to 30 mph and humidity levels dropping as low as 15 percent will sustain an elevated fire threat through 6 p.m. Wednesday. The risk stretches from Rockford and DeKalb to Chicago, Joliet, and into northwest Indiana, including Gary and Valparaiso.
Open fields, dry grass, and roadside ditches are especially vulnerable. In DuPage and Cook counties, even a parked vehicle on dry grass or a discarded cigarette could ignite flames that spread quickly with the wind. Rural areas near La Salle, Livingston, and Kankakee counties face heightened concern due to exposed farmland and ongoing spring fieldwork.
Emergency officials urge residents to avoid burning debris, limit use of equipment that creates sparks, and secure trailer chains that could drag along roadways. Fire crews may face rapid spread conditions if ignition occurs, particularly along highways like I-55, I-80, and I-90 corridors.
The elevated fire danger will ease after sunset as humidity recovers and winds weaken, but additional advisories could be issued if dry conditions persist into Thursday.
