Overview
- Heavy overnight rain produced localized flooding that pushed back Day 3 doors to midafternoon and led organizers to cancel or shorten most acts scheduled during the multi-hour delay.
- Following Saturday's heavy overnight rain, high-traffic areas such as Hutchinson Field were waterlogged and crews worked to pump out stages before allowing attendees in.
- The National Weather Service issued flood advisories for Chicago and the City of Chicago and festival promoters set up evacuation shelters at Grant Park North, Grant Park South and the Millennium Lakeside Garages.
- High-profile lineup changes included Lil Uzi Vert's weather-related Friday cancelation and later unconfirmed reports of a surprise appearance, while Wolf Alice and CORTIS had their sets cut short as crews reshuffled the schedule.
- Despite the conditions, large crowds largely attended using ponchos, streaming of the event continued, and organizers maintained heightened medical, transit and safety resources as they prepare for the festival's final day.
