Meteorological history
Danny originated in a
Due to the interaction of the initial wave and the upper-level trough, Danny maintained a "non-classical" structure resembling that of a subtropical cyclone.[1] Even after its designation as a tropical storm, the storm was highly disorganized. Little or no deep thunderstorm activity surrounded the center, and the highest winds were confined to a rainband in the northern semicircle of the cyclone.[2] The storm moved erratically northwestward throughout the day on August 26, strengthening only slightly.[1] Danny's center reformed several times, making it difficult to determine its direction of movement.[3]
By early on August 27, the tropical storm became slightly better organized, although the most intense winds were still removed from the center.
A strong upper-level trough moving through the southeastern United States forced Danny northeastward. It also triggered the formation of another low pressure system near the coast of North Carolina early on August 29. Although this low formed within Danny's cyclonic envelope, satellite imagery indicated that it did not have the characteristics of a tropical cyclone. Therefore, it is not considered to be a continuation of Danny. The new low caused the tropical storm to degenerate into a trough about 275 mi (445 km) southeast of Wilmington, North Carolina, and Danny's remnants were absorbed into a developing frontal zone shortly thereafter.[1]
Impact
In advance of the cyclone, a
As the storm remained offshore, its effects were limited. However, it generated strong rip currents and high waves along the

Danny's remnants later caused heavy rain across Atlantic Canada. At Saint John, New Brunswick, 100 mm (3.9 in) of rain flooded at least 50 basements. The Meteorological Service of Canada hoisted several weather advisories for New Brunswick, Newfoundland, Prince Edward Island and Nova Scotia.[20][21] In Nova Scotia, over 16,000 residences lost power at the height of the storm.[22]
