New Hampshire's outage risk is driven by frequent Nor'easters, ice storms, and heavy wet-snow events across the state, plus summer thunderstorm and occasional hurricane-remnant wind damage that regularly downs trees onto distribution lines in the state's heavily wooded terrain; Manchester and Nashua see dense-grid urban outage patterns, while Concord's location along the Merrimack Valley shares the same ice-storm exposure common to central NH.
