As of early Monday, 81 people died across six counties. Sixty-eight died in Kerr County alone, 40 were adults and 21 were children. Authorities said about 850 people had been rescued or evacuated. There are still 10 Mystic Camp campers and one camp counselor missing.

After floods left more than 80 dead in Texas, questions are emerging about how to provide better warnings in a region known as “flash flood alley.”
