A powerful stretch of dangerous heat is set to settle over southern New Hampshire beginning Sunday, sending temperatures soaring into the mid-90s and lasting through at least Wednesday. Residents of Manchester and surrounding communities should prepare for prolonged high heat, with escalating health risks as the days progress.
The National Weather Service has forecast a period of much above-normal temperatures from Sunday through midweek. Heat index values in Manchester and central New Hampshire are expected to reach the “moderate to major” risk range, with afternoon highs peaking near 94°F. Local officials are urging everyone to limit outdoor activities, stay hydrated, and check on neighbors, particularly those without air conditioning.
Communities such as Nashua, Concord, and Derry will experience sunny, oppressive days and muggy nights, with little relief after sunset. In response to the extreme heat, cooling centers may open if conditions worsen. Drivers and outdoor workers are advised to take frequent breaks and monitor for symptoms of heat exhaustion. Pets and children should never be left unattended in vehicles due to the risk of overheating.
This dangerous heat wave is expected to continue through Wednesday, and additional advisories may be issued if temperatures remain elevated. Residents should stay updated on local conditions and review emergency resources ahead of the worst heat.
