Chicago, IL – Wind-driven grass fires could spread rapidly across northern Illinois through Wednesday evening as warm, dry air and powerful gusts create dangerous burning conditions statewide.
According to the National Weather Service in Chicago, a Red Flag Warning remains in effect until 8 p.m. CST Wednesday for northern Illinois and parts of central Illinois. West-southwest wind gusts between 45 and 50 mph combined with low humidity and unusually warm February temperatures are elevating the risk for fast-moving brush fires.
The threat stretches from the Wisconsin border through the Chicago metro and into counties along the Interstate 80 corridor. Open fields and dormant vegetation across Cook, DuPage, Kane, Lake, and Will counties are especially vulnerable. Fire officials warn that any spark — from outdoor equipment, vehicles parked on dry grass, or discarded cigarettes — could ignite flames that spread quickly.
Emergency managers urge residents to avoid outdoor burning and delay activities involving open flames. Secure trailer chains, properly discard smoking materials, and keep vehicles off dry grass. High-profile vehicles may also encounter difficult travel on exposed roadways due to strong crosswinds.
Winds will gradually ease later Wednesday night, but dry conditions linger into Thursday. Additional advisories could be issued if fire danger persists.
