The Federal Emergency Management Agency (FEMA) has been activated in Texas, according to the Department of Homeland Security (DHS).

The activation comes in the wake of President Trump on Sunday signing a disaster declaration for hard-hit Kerr County, where at least 59 people have died as a result of the torrential rains and resulting flooding.

The U.S. Coast Guard is also helping with search-and-rescue operations in the area, according to DHS, using helicopters and other aircraft equipped with thermal cameras to search for survivors.

DHS Secretary Kristi Noem is "on the ground with Governor Abbott and local leaders on Saturday and will continue to work to make sure Texas has the resources needed to respond and recover," the DHS statement said.
