Monitor the weather and have a plan of action if severe weather is imminent.

Heat is one of the most deadly weather hazards, don't underestimate it! And with weekend 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! Animals can die of heatstroke within 15 minutes. Cracking the windows does not help, the inside still gets dangerously hot. During hot weather, keep your pets at home. If you see a pet in an unattended vehicle, do not leave until the problem has been resolved. (Statistics courtesy of www.noheatstroke.org)
