Texas GOP is incapable and incompetent at emergency management. We don't have to bother blaming the head orangeman in the white house, the inevitable truth is that the most egregious and proximate failure was on the state of Texas and it’s Department of Public Safety. No flash flood warnings? That's on Texas and its local governments, because the NWS actually did its job and had issued this PARTICULARLY DANGEROUS SITUATION/Flash Flood EMERGENCY alert at 4:23 am.
Blame republicans for over 80 deaths in Texas.
Alerts generally aren't handled at the state level. Flash flood warnings are issued by the NWS, which they did. And the Austin/San Antonio NWS station was sending out cellphone alerts in advance of the flood. The campground was sending out cell phone messages telling people to evacuate. The local police and county do not have any means to send such messages, only an opt-in web notification service that nobody is signed up for, and a facebook page.
The flood hit in the middle of the night when people weren't watching their phones and was an abrupt and unexpected and random flash flood, and in an area with poor cell coverage.
Maybe the sane reaction to this kind of tragedy isn't to go around trying to find how you can best stand on top of the corpses and harangue your political opponents, but to appreciate that America (and the world) have a long history of pretty regular natural and unnatural disasters that kill people like this. This one wasn't caused by a dam failure like so many, nor by building a city in a floodplain. Its not easily preventable nor the result of human failure.
