The search for survivors in the wake of catastrophic and historic flooding in Texas has entered its fifth day as the death toll surpasses 100 with dozens of people still missing.

A July Fourth weekend deluge in Texas caused catastrophic flash flooding that has killed at least 89 people. Camp Mystic in Kerr County says Monday morning that it is “grieving the loss” of 27 campers and counselors as the search continues for victims of the disaster.

Local officials warned the number of dead will likely rise and were due to give an update on Sunday morning, as search and rescue teams raced to find 27 girls missing from a camp near the Guadalupe River,

Six counties reported deaths from multiple severe flood events since Friday, July 4. Also, Kerrville officials reported that a privately owned drone collided with a helicopter conducting search and rescue operations.

Across Central Texas, there have been more than 90 confirmed deaths from the weekend flooding: six people were reported dead in Kendall County, seven in Travis County, four in Williamson County and four in Burnet County, officials said Monday. At least 15 people are still missing in the Austin area.

As floodwaters from the Guadalupe River begin to recede, the emotional and physical toll on Hill Country residents is only just beginning to show.
