There have been claims that NOAA/NWS did not foresee catastrophic TX floods--but that's simply not true. This was undoubtedly an extreme event, but messaging rapidly escalated beginning ~12 hrs prior. Flood Watch mid PM, "heads up" outlook late PM, flash flood warnings ~1am.

@weatherwest.bsky.social - the Guadalupe near Kerrville raised 26 feet in 45 minutes. This was a historical flood.
Indeed, and some areas saw an even faster/larger rise. Still, possibility of significant flash flooding in this region was explicitly in NWS forecast; emergency warnings issued 1-3 hours in advance of flood wave's arrival described extreme/exceptional nature of imminent threat.
@weatherwest.bsky.social - if you have ever been out in Kerrville, then you would understand why a 1 to 2 hour warning would not necessarily get to people in a timely way. It's a really small town, surrounded by rural and undeveloped areas, with camp grounds scattered in this, all with spotty cell reception.
