The November 2009 nor'easter (also referred to as "Nor'Ida") was a powerful autumn nor'easter that caused widespread damage throughout the east coast of the United States. This extratropical cyclone formed in relation to Hurricane Ida's mid-level circulation across southeastern Georgia and moved east-northeast offshore North Carolina before slowly dropping south and southeast over the succeeding several days.

The origins of the nor'easter originated from with the remnants of Hurricane Ida, a storm that formed on November 4 over the southern Caribbean Sea. After tracking through Nicaragua as a Category 1 hurricane, the system attained Category 2 status over the Yucatán Channel. Once in the Gulf of Mexico, the combination of increasing wind shear and cooler waters caused Ida to weaken. The system eventually moved over the southeastern United States on November 10 before transitioning into an extratropical cyclone. Ida eventually dissipated over the Florida Panhandle. However, Ida's mid-level circulation led to the formation of a new low over southeastern Georgia, which eventually moved off the coast of North Carolina. This new low quickly intensified and became a powerful nor'easter that caused substantial damage throughout the Mid-Atlantic States. Due to the rapid succession of these systems, United States media referred to the nor'easter as "Nor'Ida". By November 12, the system attained a minimum pressure of 992 mbar (hPa; 29.29 inHg) along with winds of 65 mph (100 km/h). In combination with a large area of high pressure, a long stretch of easterly, onshore winds impacted areas from Virginia to southern New England. Tracking parallel to the North Carolina coastline, the system eventually moved onshore near Cape Hatteras by November 13. Due to the high pressure system situated over Vermont, the low turned southeastward, bringing its center back over water. Gradual weakening took place during this period, though heavy rains continued to fall across much of the Chesapeake Bay area. On November 14, a brief secondary low developed off the coast of Delaware. Continuing to weaken, the cyclone resumed a northward track after the high weakened and persisted through November 17, by which time it had moved over Atlantic Canada.
