Colorado has sent Task Force 1 to Kerr County, Texas, to assist in searches and cleanup efforts along the Guadalupe River.

At a Wednesday morning press conference, Kerr County Sheriff Larry Leitha declined to answer a question about delayed emergency alerts, saying that an "after-action" would follow the search and rescue efforts. "Those questions are gonna be answered," he added.

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

FEMA was activated after Trump signed a Major Disaster Declaration for Kerr County, where 59 people were killed by flash floods.

Since 2016, the topic of a "flood warning system" for Kerr County has come up at 20 different county commissioners' meetings, according to minutes. The idea for a system was first introduced by Kerr County Commissioner Thomas Moser and Emergency Management Coordinator Dub Thomas in March 2016.

Over 12,000 volunteers have already assisted in Kerr County, according to the Texas Division of Emergency Management.
