Climate in Duluth

Duluth sits inland in the Georgia Piedmont, well north of any hurricane exposure -- its defining weather risks are severe thunderstorms, tornadoes, and occasional winter ice storms, not tropical systems.

A humid subtropical Piedmont climate, not a coastal one

Duluth shares the same inland Georgia Piedmont climate pattern as Atlanta and the rest of this satellite batch (base record's HOT_SUMMERS and HUMID tags): hot, humid summers and mild, generally snow-free winters, with no coastal hurricane exposure given its inland Gwinnett County location.

Severe thunderstorms and tornadoes are the real seasonal hazard, not hurricanes

The base record's TORNADO_RISK tag is explicit that inland Piedmont Georgia -- including Duluth, Atlanta, and Augusta elsewhere in this dataset -- sits in the same severe-thunderstorm and tornado corridor. Georgia's primary severe-weather season runs roughly March through May, with a secondary, smaller risk window in the fall; this is a fundamentally different hazard profile than a coastal Georgia or Florida market in this dataset, where hurricane season (June-November) dominates instead.

Occasional winter ice storms, a real if infrequent risk

Metro Atlanta, including Gwinnett County, periodically sees winter ice storms that can disrupt roads and power for days at a time given the region's limited cold-weather infrastructure relative to more northern climates -- an infrequent but real risk distinct from the summer severe-thunderstorm/tornado pattern, and one hurricane-focused hazard checklists (appropriate for coastal Georgia or Florida markets) would miss entirely.
