Why there was a 2nd tornado siren test in Hennepin County on Wednesday

You weren't hearing things. Some folks in Hennepin County heard an extra emergency siren test on Wednesday.

The second alert was heard by FOX 9 in Eden Prairie about 45 minutes after the standard test. In Minnesota, most counties test their tornado sirens on the first Wednesday of each month at 1 p.m.

In a message to FOX 9, Hennepin County officials say the second alert was not intentional -- a tech issue caused it.
