Timeline of the 2010 Atlantic hurricane season
Encyclopedia
The 2010 Atlantic hurricane season
was a hyperactive year in which nineteen tropical storm
s formed, the most since 2005
. Although Hurricane Alex formed on June 25, 2010, the season officially began on June 1 and ended on November 30. The seasons last storm, Hurricane Tomas
, dissipated on November 7.
The season had twenty-one tropical depression
s, of which nineteen intensified into tropical storms, twelve became hurricanes
, and five became major hurricanes. The high amount of activity throughout the basin was linked to the formation of La Niña
, which decreases wind shear
. The two most significant storms of the season, in terms of loss of life and damage, were Hurricanes Igor and Tomas. Hurricane Igor was a large Cape Verde-type hurricane
and was also the strongest storm of the season, reaching maximum sustained wind
s of 155 mph (250 km/h). The storm was later retired, along with Tomas, in the spring of 2011, after causing unprecedented damage in Newfoundland
. Tropical Storm Bonnie
was the only tropical storm to make landfall
in the United States during the 2010 season.
