Sustained in part by the warm waters of the Gulf Stream, Ana made landfall along the northeast coast of South Carolina early the next morning.

Heavy rainfall and gusty winds affected parts of the Carolinas, and some vulnerable beaches endured coastal flooding and several feet of erosion.

Gusty winds damaged trees and powerlines, causing sporadic power outages, and a weak tornado was reported in association with Ana.

[2] A sharp mid- to upper-level trough interacted with the system and facilitated gradual cyclogenesis, and early on May 6, a distinct, non-tropical center of low pressure developed off southeastern Florida.

[4] With the development of deep convection, the system was classified Subtropical Storm Ana at 00:00 UTC on May 8, while situated about 170 mi (270 km) to the south-southeast of Myrtle Beach, South Carolina.

[5] However, the warm waters of the Gulf Stream, coupled with atmospheric instability resulting from cold temperatures aloft, enabled the formation of curved banding features near the storm's core.

[7] Dry air and northwesterly wind shear plagued the system, keeping the strongest thunderstorms confined to the eastern side of the circulation.

[10] Diminished by the cooler waters over the continental shelf, Ana made landfall along the coast of South Carolina, near North Myrtle Beach, at around 10:00 UTC on May 10.

[19] Shifting volumes of sand in Surf City exposed the structure of the wrecked schooner William H. Sumner, which grounded in 1919 and is occasionally visible along the beach.

[20] On May 7, heightened swells in the Charleston Harbor drove a sailboat aground, forcing the Coast Guard to rescue the stricken vessel's two occupants.

[21] Rip currents from the storm pulled a swimmer underwater for over ten minutes off Oak Island; the man died of his injuries the next day.

[25][26] Near Richlands, North Carolina, gusty winds toppled a tree onto a roadway, causing a traffic accident that left one man dead.
