Calvert County residents are urged to take the following precautions to protect themselves and their families when temperatures rise: · Download the Calvert County Government mobile app on the Apple App Store or Google Play Store and enable push notifications for the latest weather updates and county press releases.

· Drink plenty of water, even if you do not feel thirsty. Avoid alcohol and excessive caffeine, which can contribute to dehydration.

· Stay in air-conditioned buildings whenever possible and limit outdoor activities during the hottest part of the day. If you must be outdoors, wear sunscreen, seek shade when available and take frequent breaks in a cool location.

· Check on older adults, young children, people with chronic medical conditions and neighbors who may be more vulnerable to extreme heat.

· Know the signs of heat-related illness. Symptoms of heat exhaustion may include heavy sweating, dizziness, nausea, headache and weakness. Heat stroke is a medical emergency and may cause a high body temperature, confusion, loss of consciousness or hot, dry skin. Call 911 immediately if someone shows signs of heat stroke or heat related illness.

· Never leave children or pets in parked vehicles, even with the windows down. Temperatures inside a vehicle can become deadly within minutes.

· Provide pets with fresh water and shade or bring them indoors during periods of extreme heat. Limit walks to cooler morning or evening hours and avoid hot pavement that can burn paws
