Details:
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 the coastal plain of Maine and southeast New Hampshire today. This afternoon, relative humidity values will decrease to low levels between 25 to 30 R.H. %. At the same time, north to northeast| winds between 10 to 15 mph with frequent gusts to 20 mph will continue to dry fuels and increase fire spread potential. Near the coast, a sea breeze will develop this afternoon with southeast winds gusting to 20 mph. 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. |
