Special Weather Statement issued April 28 at 6:59AM EDT by NWS Gray ME

Effective: Tue April 28, 2026, 6:59 AM
Expires: Tue April 28, 2026, 8:00 PM

A very dry air mass and breezy conditions will combine with dead and dry fuels such as grass, leaves, and twigs to create the potential for uncontrolled fire spread across southern New Hampshire today. Afternoon relative humidity values will decrease to low levels between 25-35 percent away from the coastline. At the same time, southeasterly winds between 5-15 mph with frequent gusts to 20-25 mph will continue to dry fuels and increase fire spread potential. Wind gusts are expected to diminish later this evening with increasing relative humidity values. Extra caution should be taken to prevent wildfires. Always consult with fire officials before engaging in any open burning activities and comply with all applicable laws and regulations. Never leave an open fire unattended and always extinguish campfires completely before leaving.

The times presented here are based upon the solunar theory, which is the idea that the movements of fish and other animals are affected by the location of the sun and moon. The major periods are believed to be the times of the greatest animal activity and occur when the moon is directly overhead or underfoot (lunar transits). The minor periods also see increased activity and occur when the moon is rising or setting. The strongest activity occurs during full or new moons, and the weakest during quarter or three quarter moons. This is indicated by the Action Rating.
