Overview
- Organizers announced a doors delay to 2 p.m. on Saturday because of overnight and ongoing heavy rains that have produced flood advisories and warnings for the Chicago area.
- At least one high-profile act, Lil Uzi Vert, canceled a scheduled set and several other performances were delayed or called off after storms hit on Friday.
- The City of Chicago and Lollapalooza promoters established evacuation shelter sites at Grant Park North, Grant Park South and the Millennium Lakeside Garages and posted evacuation procedures for attendees.
- Event teams deployed public-health resources on site, including fentanyl-education booths and free Narcan, plus water stations and medical staffing to handle weather- and crowd-related needs.
- Despite the weather, many festivalgoers arrived using permitted rain gear such as ponchos, and transit agencies added service to manage the large crowds for a festival that features more than 170 performances over four days.
