Staying Safe During an Early July Heat Wave

A large heat dome has trapped very warm air over much of the central and eastern United States this week. The National Weather Service has issued heat advisories and warnings for many areas, and energy demand has increased as air conditioners run continuously. Temperatures have climbed toward triple digits in parts of the Midwest and interior Northeast, and humidity has made conditions feel even hotter.

Forecasters expect a cold front and rounds of thunderstorms to move along the northern edge of the heat ridge, so relief may arrive for the Great Lakes and parts of the Northeast over the weekend. While some lakeshore communities will feel cooler winds, the Mid-Atlantic and Southeast will stay hot with little overnight relief. Vulnerable people are being advised to use cooling centers where they are available, stay hydrated, and limit strenuous outdoor activities during peak afternoon heat. Power providers have warned of high electricity demand and residents should conserve where possible. Check local guidance for shelter and cooling hours.
