Two Texas nonprofits and a number of GoFundMe campaigns have raised nearly $2 million to support families impacted by the Hill Country floods.

Flash flooding in Texas Hill Country, triggered by intense thunderstorms, has resulted in at least 81 deaths, including at least 28 children. Camp Mystic, a girls' camp located on the Guadalupe River, confirmed at least 27 deaths among campers and counselors.

Rescuers searched the Guadalupe River for survivors of the Texas floods that killed more than 100 people over the July Fourth holiday weekend, with an unknown number of people still missing. The basin area was crowded with families and campers preparing to enjoy the holiday when pounding rain brought about catastrophic flash floods just before dawn Friday.

Two sisters who died in the Texas flood disaster were found with their hands “locked together,” according to family.

Flash floods swept across central Texas on Friday. More than 80 people have died, and many are missing, according to the Associated Press. Flooding struck as the Guadalupe River surged by more than 20 to 26 feet within 90 minutes,
