Multiple parts of Central Texas, including Kerr County, were shocked by flash floods Friday when the Guadalupe River and others rose rapidly.

More than an hour passed between Camp Mystic receiving a severe flood warning and a decision to evacuate young campers asleep in cabins by the Guadalupe River.

Camp Mystic's executive director began evacuating campers approximately 45 minutes after the National Weather Service issued a "life-threatening flash flooding" alert.

At least 19 of the cabins at Camp Mystic were located in designated flood zones, including some in an area deemed “extremely hazardous” by the county.

FEMA removed dozens of Camp Mystic buildings from its 100-year floodplain map for Kerr County, the AP reports.

The number of people reported missing in Kerr County, Texas, as a result of last week’s flash floods continues to soar. Authorities say search teams combing through the debris and destruction there are looking for more than 160 people who disappeared in the raging waters.

The Federal Emergency Management Agency included Camp Mystic in a "Special Flood Hazard Area" in its National Flood Insurance map for Kerr County, Texas, in 2011.

Multiple buildings at Camp Mystic in Texas, one of the many areas impacted by the flood disaster over the 4th of July weekend, were removed from Kerr County’s 100-year flood map, according to a report.
