The United States had fewer strong hurricanes develop in 2007 than had been predicted. Although activity was below-normal, La Nina's impact over the Atlantic was weaker than expected. This resulted in stronger upper-level winds and increased wind shear over the Caribbean during peak hurricane season.

As a whole, the 2007 Atlantic hurricane season produced a total of 14 named storms, including six hurricanes. Two became major hurricanes. Some other interesting facts:

• One hurricane, one tropical storm and three tropical depressions struck the United States: Tropical Depression Barry on June 2, Tropical Depression Erin on Aug. 16, Tropical Depression Ten on Sept. 21, Tropical Storm Gabrielle on Sept. 9, and Hurricane Humberto on Sept. 13.
• Eight storms formed in the Atlantic Basin during September — tying September 2002 for having the most storm formations during any given month.
• For the first time in recorded history, two Category 5 hurricanes made landfall in the Atlantic Basin during the same season. Hurricane Dean hit the Yucatan Peninsula near Costa Maya on Aug. 21 with 165 mph winds, followed by Hurricane Felix on Sept. 2, near Punta Gorda, Nicaragua, with 160 mph winds.
• Hurricane Humberto grew from a tropical depression with top winds of 35 mph into a hurricane with winds of 85 mph within 24 hours — only three others storms (Celia 1970, Arlene and Flora 1963) intensified faster during a 24-hour period from below tropical storm strength.
