Doesn’t sound good,cars turning around on the freeway.
I’m so frightened for the people stuck in traffic. If it were me I would not stay in the car but would be out in a field.
There was a very unusual traffic jam right before the storm hit. The roads wouldn’t have normally been as busy at that time of night, but I think a lot of folks chose to bug out. That only works if you leave well in advance of storms. About 1/2 hour out from getting hit? Too late. Hunker down in place is best bet. I heard there were many accidents, and a lot weren’t caused by the tornado. They were caused by people whipping at very high speeds around others on the highways in a mad attempt to escape or get home in time to beat storms. I was passed by several folks going probably at least 90 MPH.
