What could the Federal government have done with more people that it was supposed to do that contributed to this flood or the damage it caused?
I don't put a lot of stock in search results with AI tools, and I don't use them as sources. I don't know who set the parameters of the search they use or the criteria and script for the answer they present.
No, they don't. Your source says,
"Texas officials pointed fingers at the National Weather Service, which they said issued forecasts earlier in the week downplaying the impending storm and its severity." IOW, "Local Texas Officials" don't complain that there weren't enough warnings, but that the warnings all week long weren't accurate enough.
And your source goes on:
"But in a statement to NBC News, the NWS said it was “heartbroken by the tragic loss of life in Kerr County,” and added it had issued flash flood warnings the night of July 3 and then again the morning of July 4.
Tom Fahy, legislative director for the National Weather Service Employees Organization, said local NWS were adequately staffed and “issued timely forecasts and warnings leading up to the storm.”
That's the Union, BTW.
When there's a credible cause and effect relationship. (At a minimum, when a cited, credible source shows such a relationship and not when the source works against it.)
