Minneapolis officials blame 'technical glitch' for tornado sirens that woke up everyone at 6 a.m.

People in Minneapolis woke up around 6 a.m. on Tuesday to the blaring sound of emergency tornado sirens. 

The weather was nice. There was not a cloud in the sky. And there was no indication of an impending aerial attack.

Turns out, the sirens were a "technical glitch."

"There was a software issue which in turn activated the sirens," Hennepin County Emergency Management wrote on Facebook.

"Looks like the statewide tornado drill came early thanks to a false alarm," the sheriff's office added. "Dispatch is working to figure out why sirens went off County wide."
