FS&S Thunderbolt 1000T | 1 Min. Alert & Attack | Minneapolis, Minnesota | 8/6/25

Details

Description

At 13:00:08 on Wednesday, August 6th, 2025 Hennepin County conducted a monthly test of the City of Minneapolis Outdoor Warning Sirens which consisted of a 1 minute Alert and 1 minute Attack.

I knew I wanted to make a stop in Minneapolis for a test. Originally we were going to go to an OA2 downtown and get an eye level shot from a parking garage, only because the Thunderbolt has been recorded so many times. But after talking with Brodie we decided it would be better to just record the Thunderbolt. Looking back now I think it would have been pretty stupid to come here for the first time and not record the Thunderbolt
