Minnesota Gov. Tim Walz says one of the state's elite K-9 units is heading to central Texas to aid in search and recovery efforts following the devastating floods.

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

If you would like to volunteer to help with flood recovery, the city said to register in advance online. Registered volunteers are asked to come to Tivy Antler Stadium, located at 1310 Sydney Baker Street in Kerrville. Check-in starts at 8 a.m.

In the last nine years, federal funding for a system has been denied to the county as it contends with a tax base hostile to government overspending.

FEMA records obtained by NBC 5 Investigates show that Kerr County officials did not use FEMA’s Integrated Public Alert & Warning System to send warnings with safety instructions to all mobile phones in the affected area during critical hours as the flooding began on July 4.

A Kerrville-area river authority executed a contract for a flood warning system that would have been used to help with emergency response, local officials said.

Crews are using construction equipment to clear vehicles, trees and homes in a race to locate more than 170 people still missing since Friday’s devastating flood.

President Donald Trump was expected to arrive in Kerr County, Texas, Friday afternoon, one week after the area was struck by catastrophic flooding.
