Would have done no good. The weather alert for the area was at about 4A — and that was applicable to most of central Texas. 20 minutes later the weather folks realized that tons of rain was going to hit that specific area — much too late to wake and evacuate anyone.
Hills and poor predictive technology combine to put this into the same risk category as an earthquake — you know there is an earthquake when it happens. Ditto on flash floods.
The only real “protection” is to limit such camps to large lake shores — where a flash flood dissipates.
Although this is a good idea, the best method to avoid the danger is the one they don't want to hear about or admit. That is, don't be in the area when it's storming.
Are they supposed to stay up all night?
The tornado warnings come across on the cell phone...loud enough to wake me up. I’ve heard that areas of rural Texas don’t have coverage?
How many more towers would it take to get complete coverage?
