Quickly pull over, bring up a weather app on your smart phone, look at the radar track and proceed at right angles to the storm cells’ path at high speed, keeping an eye out for places to shelter.
Local news stations’ web broadcasting of storm coverage (in Dallas-Fort Worth anyway) is also something good to log into for this purpose.
Agreed. Except I don’t have a smart phone. B4 digital, one could get radios to monitor local TV stations, who usually do a good job tracking tornados in their coverage area. Maybe somebody makes a digital OTA tv tuner that can run off 12 volts?
