There’s all this focus on the NWS/NOAA not sending warnings early enough. Not from what I can tell, they were sending out warnings. And Kerr County, where many of the deaths have been, doesn’t have a local flood warning system because they didn’t want to pay for it.
If the warnings were louder, their parents would have done something. Why are you counting your "not from what I can tell" as data?
Edit:
People have reported receiving text message alerts on their mobile phones early on Friday morning, warning them of flooding. Some residents told the New York Times they did not understand the seriousness of them and others said they never received any at all.
