NWS says Flash Flood Warnings were issued on July 3 and early July 4 in Central Texas, giving more than three hours of warning.

Texas leads the country in flood deaths. Steep hills, shallow soils and a fault zone have made Hill Country, also called "flash flood alley," one of the state's most dangerous regions.

Social media users are spreading false claims that flash floods in Texas that killed more than 100 people over the Fourth of July holiday weekend were caused by weather modification.
