Don’t they have sirens? Anywhere there are tornadoes they should have them.
1. Sirens are going out of fashion for emergency warning. I don’t think there is an operational siren in my county. Air conditioning, well insulated homes, and double pane windows, have reduced the utility of sirens, which came into vogue before central heating and air conditioning, and when houses in Texas tended to be made with thin wood walls, with no insulation.
2. Even back when sirens were used, Texas is a big place and covering the entire state with warning sirens would have been a massive project.
No, they have moved to the trendy new cell phone text message alerts. Nevermind that not everyone sleeps with a phone, has cell in those valleys, has a phone that hasn’t gone dead, isn’t 8 years old with no phone, you are 80 and leave your phone in the kitchen to charge at night, or that a Weather Service rain alert is not the same as a confirmed Flash Flood warning from river gauges.
They sent you a text you know!
