High Quality Content by WIKIPEDIA articles! Hurricane Danielle was the first of four Category 4 hurricanes during the 2010 Atlantic hurricane season. The sixth tropical depression, fourth named storm, second hurricane, and first major hurricane of the season, Danielle developed as a typical Cape Verde-type hurricane from a tropical wave on August 21. Quickly intensifying, the new tropical depression became a tropical storm eighteen hours after formation on August 22, and it reached category 2 on August 24. Also on August 24, Hurricane Danielle weakened back to a category 1 hurricane, but it returned to category 2 strength on August 25. Further intensification occurred and Danielle became a Category 4 hurricane with peak winds of 135 miles per hour (217 km/h) on August 27. It then weakened, and finally dissipated on August 30. The hurricane was the first in a rapid succession of eleven named storms, which ended in late September.
