I filmed this video from Pierre, South Dakota on 29 June 2018 as a severe thunderstorm approached the Capitol City.

This storm had a history of producing a radar confirmed tornado, baseball size hail and hurricane force winds along with torrential rainfall.

The main siren heard is a Federal Signal 2001SRN sounding Steady Signal. The rotation is set to 8 RPM. You can faintly hear the new Whelen system in the background doing a voice message.
