KEENE, N.H. (MyKeeneNow) Keene-area residents are being urged to take precautions as dangerously hot and humid weather is expected to settle over the region beginning Wednesday afternoon and continue through Friday evening.

According to the National Weather Service in Gray, heat index values could reach as high as 110 degrees across southern New Hampshire, creating conditions that significantly increase the risk of heat-related illnesses. Overnight temperatures are expected to remain in the 70s, limiting relief from the heat and allowing heat stress to build over multiple days.

City officials are encouraging residents to drink plenty of fluids, stay in air-conditioned spaces whenever possible, avoid prolonged time in the sun and check on older relatives, neighbors and others who may be vulnerable to extreme heat.

Officials also reminded residents never to leave children or pets unattended in parked vehicles, noting that temperatures inside a vehicle can become deadly within minutes.

For those without air conditioning, several public facilities are available to help people stay cool. Wheelock Park Pool and Robin Hood Park Pool are open weekdays from 1 to 6:45 p.m. and weekends from noon to 5:45 p.m. On Independence Day, both pools will operate from 10 a.m. to 2 p.m. Admission is $2 per person, with season passes also available.

The Keene Public Library is also open as a cooling option Wednesday and Thursday 10 a.m. to 6 p.m.

Additional cooling locations may be available through the Keene Family YMCA, the Keene Salvation Army, Hundred Nights Shelter and Services, the Monadnock Aging & Disability Resource Center and the Keene Serenity Center. Check with these locations for specific hours.

The National Weather Service advises anyone spending time outdoors to stay hydrated, seek shade or air conditioning frequently and watch for signs of heat exhaustion or heat stroke. Extreme heat is expected to persist through Friday evening.
