Chicago's festival season has begun and city officials are reminding the public to stay safe in case of severe weather.
The city's Office of Emergency Management and Communications says workers have recently installed signs that direct crowds to extreme weather shelters. They are generally for attendees of large-scale events like movie nights in the park and Lollapalooza.
There are more than a dozen signs that have been installed that direct people to safe locations in case of torrential rain, high wind, lightning or tornadoes. The signs are blue and white.
In addition, people seeking shelter can go to parking garages underneath Millennium Park.
