Six Flags Great America and Hurricane Harbor Chicago are closed Friday, July 17, as Canadian wildfire smoke keeps air quality at hazardous levels around Gurnee.
The parks plan to reopen Saturday as scheduled. Six Flags made the decision after reviewing current conditions and guidance from weather and safety experts, according to NBC Chicago's local report.
Six Flags Great America closed at 3 p.m. Thursday as the smoke thickened. Friday's full-day shutdown extends the disruption to a second day.
The air quality alert covering Lake County remains in effect through Friday night. Guests planning a Saturday visit should check Six Flags Great America's current operating status before leaving home.
