Heat is one of the most deadly weather hazards, don't underestimate it! And with temperatures expected to top out over 100°F, now is the time to prepare. Heat can escalate quickly and become dangerous. So drink plenty of water through the day, even if you don't feel thirsty. Wear loose-fitting, light-colored clothing. Spend time in air conditioning and in the shade. And never leave people or pets alone in a car! 38 kids die each year by being left in an unattended vehicle. 88% are ages of 3 and under. 54% were forgotten by a caregiver. 100% of these deaths can be avoided!
