Tonight's performances are now scheduled to end around 10:45 p.m.
Festival-goers were evacuated Saturday afternoon from Grant Park and directed by staff and the Chicago Police Department to pre-established underground evacuation and shelter sites along Michigan Avenue.
Organizers working with the Chicago Office of Emergency Management and Communications have been monitoring the storm and determined weather conditions are safe for people to return and Lollapalooza to resume.
Saturday's updated schedule can be found on Lollapalooza's official website.
ABC7 will have complete live coverage at 10 p.m.
