Due to the high probability of heavy rain and lightning, the University Commencement Ceremony will move to the Purcell Pavilion at the Joyce Center, beginning two hours earlier than scheduled, at 8 a.m. Individual diploma ceremonies also will start earlier than scheduled, at noon Sunday. Only guests with a red severe weather ticket will be seated in Purcell Pavilion. For guests without a ticket, a closed-circuit broadcast will be available in the north dome of the Joyce Center; in auditoriums in the DeBartolo Hall classroom building, Jordan Hall of Science and Compton Family Ice Arena; and on commencement.nd.edu and WNIT2 (Channel 34.2). Doors to the center will open at 7 a.m. There will be no procession by the graduates or faculty, who may enter through any door and seat themselves beginning at 7 a.m.
