I live right on Bixby / South Tulsa border and in the 2.5 years we have been here. I can't think of a single time we have heard sirens during a storm. I been around Tulsa metro most of my life and can't even really think of a lot of Tornadoes in this area. Seems like they almost always go out I-44 by the turner turnpike gate then head North East towards Catosa. I did see a couple small ones around Skiatook and remember the bad one that came though in 94 or 95."Man the sirens were going for a good while south of the creek turnpike.."
That's the thing about the sirens. Microburst: sirens. Flash flood warning: sirens. Tornado watch: sirens. Tornado warning: sirens. Tornado: sirens. Equipment malfunction: sirens.
When we had the Tornadoes go through Tulsa in 2017 that hit around 41st and Sheridan in the middle of the night and went east. I was on call that weekend. I had been all the way up to Kaw lake during the storm. I was making my way back down 169 and was directly in the path of that tornado and didn't know it. I know now because worked called at that exact time and I was on bluetooth with them and storm was about 2 miles west of me. I went to bed told them let me sleep a few hours and when storms cleared I would be back out in the morning. I got up the next morning headed up Sheridan and saw the roads closed. It was a long day.
