Special Weather Statement
Special Weather Statement issued April 27 at 2:53PM EDT by NWS Gray ME
Apr 27, 2:53 PM
→ Apr 28, 2:00 AM
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 on Tuesday. 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 Tuesday 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.
