Update: As of 10:25 a.m. power was restored to all towns and counties that lost power.

In an unprecedented move, classes were delayed Monday until 11:30 a.m. due to a massive power outage.

Buildings received power shortly before 9 a.m. but remained on lockdown until 9:30 a.m. in order to restore heat to the facilities. While power is still out in parts of Rexburg, four out of the six central circuits have been restored at this point according to representatives of Rocky Mountain Power.

Emergency calls and texts were sent to students informing them of the delayed schedule and shelter available at the BYU-Idaho center.

This is the first time BYU-Idaho has used their emergency notification system to inform nearly all its students.

Hundreds of students lined the walls of the I-Center, doing homework, reading, some even sleeping to wait out the power outage.
