Multiple urban search and rescue teams from across the country that responded to the deadly floods in central Texas told CNN they were not deployed by the Federal Emergency Management Agency until at least Monday evening — days after any victim had been found alive.

At least 161 are still unaccounted for after the July Fourth floods that saw the waters of the Guadalupe rise to historic levels in Central Texas, officials with Kerr County said Friday. Authorities have confirmed 103 deaths, 36 of whom are children.

Nearly a week after deadly floods struck Central Texas, search and rescue teams are continuing to probe debris for those still missing.

At least 87 people are dead after heavy rain led to devastating flooding in Texas. Kerr County was hit the hardest, with at least 75 deaths, including 27 children. President Donald Trump signed a disaster declaration for the county and the Federal Emergency Management Agency is on the ground there.

This part of Texas Hill Country is known for flash floods. Why were so many people caught off guard when the river turned violent?

The organizations working together to help the flood victims said that 'no additional in-kind donations (clothing, food, supplies) are needed in Kerrville.' They said the best way to help is with monetary donations.

Torrential rain flooded creeks, streams and the Guadalupe River, where the water swelled more than 26 feet in 45 minutes.

With more than 170 still missing, communities must reconcile how to pick up the pieces around a waterway that remains both a wellspring and a looming menace.
