Leon
$100M damage
What happened
Significant, widespread drought conditions persisted across North Texas throughout the month. This drought now ranks as the worst in North Texas since the severe multi-year drought of the 1950s. The U.S. Drought Monitor continued to place the region in the exceptional drought category, D4, which is the worst possible category and is reserved for particularly damaging events. Disaster declarations remained in place for Collin, Comanche, Hood, and Parker Counties in North Texas. Federal law dictates that these as well as all bordering counties are eligible for federal disaster assistance. This August marked the greatest number of 100-degree-days ever for the month at Waco, with a total of 27 days that reached or exceeded 100 degrees. The previous record of 26 days was set in 1951. Dallas/Fort Worth set a streak of 19 consecutive 100-degree-days, which ranked 6th on the list of longest 100-degree-day streaks. In fact, Dallas County even considered declaring a heat emergency due to the very hot days and hot nights.Already low water resources dropped even further due to higher summertime water usage and evaporation rates. Most lakes remained well below conservation pool,...
