CONCORD, NH – The New Hampshire Department of Safety’s Division of Homeland Security and Emergency Management (HSEM) urges residents and visitors to use caution during the dangerous extreme heat expected in most parts of the state through Friday.
The National Weather Service (NWS) in Gray, Maine, issued an Extreme Heat Warning for Hillsborough, Belknap, Strafford, Cheshire, Merrimack, Rockingham, Carroll, Sullivan and Southern Grafton counties from 11 a.m. Wednesday to 8 p.m. Friday. NWS issued an Extreme Heat Advisory for Coos and Northern Grafton counties from 11 a.m. Wednesday to 8 p.m. Thursday.
Much of New Hampshire is expected to have temperatures in the 90s with high dew points that will make temperatures feel like more than 100 degrees. Extreme heat killed 529 people in the United States in 2024, according to the NWS.
“Extreme heat can be deadly if you don’t take the proper steps to keep yourself and loved ones safe,” said HSEM Director Robert Buxton. “Stay hydrated and limit the time you spend outdoors if possible. If you must work outside, take frequent breaks. Check in on friends and neighbors and pay close attention to those that may be more sensitive to the heat such as the elderly and children.”
Director Buxton offers these heat safety tips:
- Stay informed by monitoring National Weather Service weather reports to keep track of changing conditions.
- Stay indoors as much as possible and avoid exposure to the sun.
- Never leave children or pets alone in vehicles.
- Stay on the lowest floor if there is no air conditioning available. Heat rises.
- Know the signs of heat exhaustion and heat stroke.
- Check for the nearest cooling center in your area by calling 211.
