Extreme Heat Safety

As we head into late August, we are continuing to see temperatures 10-15 degrees above normal. The forecast highs this weekend are even expected to tie or exceed the record daily high in DFW on Saturday and Sunday! This abnormal pattern is expected to continue into early next week.

Heat can escalate quickly. Warm temperatures can quickly become dangerous. Heat is one of the most deadly weather hazards - don't underestimate it. Never leave people or pets alone in a car. Drink plenty of water, even if you don't feel thirsty. Wear loose-fitting, light-colored clothing. Spend time in air conditioning and in the shade.
