Oklahoma’s governor declared a state of emergency for 25 counties Thursday, a day after severe weather whipped through large swathes of state, resulting in one death and widespread power outages.

Governor Mary Fallin announced the declaration in the city of Moore, after touring a stricken elementary school, according to NBC News. No students or staff were injured at the school, which was closed when the tornado hit.

“It’s hard to believe that two years later, we’re back at a Moore public school, surveying damage,” Fallin said. “I am very thankful that this school did not sustain damage during school hours.”

Outside Tulsa, a tornado cut through a mobile home park in the suburbs of Sand Springs Wednesday night, killing at least one person and injuring three others.

“Right now, rescue efforts are continuing and officers are aiding the injured and helping those who need immediate medical care,” Shannon Clark, with the Tulsa County Sheriff’s Office, told CNN. “It’s very tough conditions right now — very touch and go. The conditions my people are working in right now are deplorable at best.”

Further south, near Oklahoma City, officials reported that another tornado touched down outside the town of Moore, overturning vehicles, uprooting trees and injuring at least three people. However, no deaths were reported in the area.

Thousands of Oklahoma residents were without power early Thursday as officials mobilized rescue efforts.
