Temperatures may be cooler along the lake shores.
To stay safe during high heat events, take action to protect yourself and others. Determine if you or others around you are at greater risk of heat illness. Check on older adults, those living alone and other at-risk people in-person or on the phone multiple times a day.
Watch for the early signs of heat exhaustion in yourself and others. Signs may include headache, nausea, dizziness, thirst, dark urine and intense fatigue. If you experience these symptoms, stop your activity and drink water.
Be sure to drink water often and before you feel thirsty to replace fluids. Close blinds, or shades and open windows if outside is cooler than inside.
