The National Weather Service has issued an Excessive Heat Watch for Mercer County and the surrounding area from Wednesday morning, July 17, through Sunday evening, July 21, and County Executive Brian M. Hughes is reminding residents that many cooling sites are open. An Excessive Heat Watch means that a prolonged period of hot temperatures is expected, with hot temperatures and high humidity combining to create a dangerous situation in which heat illnesses are possible.

To cope during extreme heat, drink plenty of water, even if you are not thirsty, and spend as much time as possible in an air-conditioned environment.

Hot weather can impact everyone, regardless of age or condition, but some people are more at risk than others. People most at risk include those over age 65, individuals with medical conditions, those taking medications that may affect the way the body reacts to heat, people with disabilities, pregnant women and breastfeeding mothers, babies and young children, those who are overweight or obese, individuals who work or exercise outdoors, and even those residents who may have recently arrived from cooler climates. Never leave children, pets, or anyone with limited mobility alone in hot vehicles. Even with the windows rolled down, only minutes in a hot car can be deadly. Be sure to check on elderly relatives and neighbors.

Mercer County also offers designated cooling sites including all municipal senior centers and all Mercer County Library System branches. Call individual locations for daily hours of operation. These locations are open to all residents.
