2010 Atlantic hurricane season
On August 19, Tropical Depression Six formed close to Africa. On August 22, Tropical Depression Six strengthened to become Tropical Storm Danielle. The next day the storm strengthened further and became Hurricane Danielle, a Category 2 hurricane. Suddenly bad conditions in the atmosphere meant that Danielle weakened back to a tropical storm. A few hours later Danielle strengthened to a hurricane for a second time, reaching Category 4 strength. As Danielle went over the colder waters of the north Atlantic it weakened, and was no longer a hurricane east of Newfoundland. Danielle was never a threat to land.
