by A scorching wave of summer heat is expected to hit southern New Hampshire on Thursday, July 24. In Manchester, the heat index will soar close to 97°F, making driving along I-293 especially dangerous for people who aren’t ready. Because of this dangerous weather alert, local officials are telling people to take instant safety precautions because the heat is expected to get worse through Friday.
As of Thursday afternoon, the National Weather Service says the temperature will rise into the mid to high 90s. The risk is highest on Friday, when hot, muggy air could make conditions so bad that they break records. People who spend a lot of time outside or commute along big roads like I-293 are most likely to get sick in Hillsborough County and the Manchester metro area. Health experts say to limit strenuous outdoor activities, stay hydrated, and check on elderly neighbors or anyone who doesn’t have a reliable way to cool off.
The southwest winds won’t help much, and power companies say that energy use may go up as air fans work longer. Schools, daycares, and people who work outside should go over heat safety rules again. Also, people in the area should not leave their kids or pets in their cars, even for a short time.
The threat changes Friday night as a line of thunderstorms and showers comes through. There may be a short break before Saturday’s partly sunny and warm weather returns. Looking ahead, a few showers may stick around until Sunday, but by Monday and Tuesday, it will be mostly sunny and less muggy.
