Mix of 2001's and dual tone Thunderbolts in Attack

[ver tum]

This is a great mix of 2001's and dual tone Thunderbolts sounding in Attack for a tornado warning. I'm not sure where it was filmed.

The high pitched Thunderbolt with the unusually slow wind-downs sounds spooky with the other sirens.

I've seen this video. The sirens were great. The clouds looked pretty scary.
