Due to the power outage, a campus wide alert notified students early this morning of an evacuation plan that would move all residents to the North Dining Hall at the University of Notre Dame.

Shuttles began transporting students from the closest exits of each residence hall within fifteen minutes of the notification, with mandatory evacuation in place by 9:30 this morning. Students have been told to dress warmly and bring a bag of essential items.
