Connecticut's outage risk is driven by Atlantic Nor'easters, hurricane-remnant winds, and heavy wet-snow and ice accumulation across its densely wooded suburban terrain, which regularly downs trees onto aging distribution lines; Hartford's inland river-valley grid faces prolonged ice-storm restoration times, Stamford's coastal Fairfield County location sees the earliest wind and surge impacts from Atlantic storms, and New Haven's harbor-adjacent grid shares similar coastal storm exposure.
