Hurricane Danny
Early on August 16, the NHC began monitoring an area of disturbed weather in association with a tropical wave south-southwest of the Cape Verde Islands.[42] Amid generally favorable atmospheric conditions, the system organized into a tropical depression by 15:00 UTC on August 18 and further intensified into Tropical Storm Danny six hours later.[43][44] The entrainment of the Saharan Air Layer early on August 19 caused a collapse of associated convection, although it was noted that a vigorous circulation remained.[45] Shower and thunderstorm activity congealed into a small central dense overcast, and a small eye became evident, supporting an upgrade to hurricane intensity at 15:00 UTC on August 20.[46] Tracking west-northwestward, Danny continued to intensify and a recon flight the next day indicated that the cyclone had attained peak winds of 115 mph (185 km/h), the first major hurricane of the season.[47] Danny had an unusually high intensity of 974 mbar - an intensity usually found in Category 2 hurricanes. Following peak intensity, a combination of stronger wind shear and drier air caused Danny to rapidly weaken to a minimal tropical storm by the afternoon of August 23.[48] On August 24, Danny dissipated 45 miles (72 km) west-southwest of Guadeloupe.
