Safety Reminders

With heat index values expected to reach 109F to 110F, it is critical to take precautions against heat-related illness. Stay hydrated by drinking plenty of water, even if you do not feel thirsty. Limit outdoor exertion, especially during the midday hours when the sun is strongest.

Check on neighbors and elderly relatives who may be vulnerable to the heat. If you must be outside, seek shade or air-conditioned spaces frequently. Wear lightweight, light-colored clothing and a hat to help protect against the intense sun.

Do not leave children or pets in parked vehicles, as temperatures inside can rise rapidly to life-threatening levels.
