Lancaster, NH – Gardeners and early risers in northern New Hampshire and western Maine should prepare for a chilly morning Friday, as the National Weather Service has issued a frost advisory.
According to the NWS office in Gray, ME, the advisory covers Northern Oxford County in Maine, along with Northern and Southern Coos Counties in New Hampshire. It will be in effect from 2 a.m. to 8 a.m. Friday, September 12.
Forecasters warn that temperatures could dip as low as 34 degrees in the region’s colder valleys overnight. That will be enough to trigger frost formation, particularly in sheltered, low-lying areas. Sensitive plants and vegetation could be damaged or killed if left unprotected.
Residents are urged to take precautions by covering tender plants or bringing them indoors before nightfall Thursday. The NWS advises that simple steps, such as using blankets or specialized coverings, can help protect gardens and potted plants from frost damage.
This marks one of the season’s first widespread frost advisories in northern New England, signaling the transition toward cooler autumn nights. While widespread freezes are not yet expected, the advisory highlights the need for residents to start preparing for rapidly changing fall weather.
Temperatures are expected to rebound after sunrise Friday, with daytime highs returning to more seasonable levels.
