The 2013 Atlantic hurricane season was a slightly above average season, in terms of named storms, but very below average in terms of hurricanes and major hurricanes; with this season being the first since 1994 with 0 major hurricanes, and the first since 1968 that had its strongest system being a Category 1 hurricane. 15 depressions formed, with 13 becoming tropical storms, 1 subtropical storm was discovered in a post-season analysis and as such, was not named. 2 of those tropical storms, became hurricanes, but as the strongest hurricane was a only a high-end Category 1, none of the hurricanes became major hurricanes. The lack of strong storms was due an "unexpected significant weakening of the Atlantic Ocean thermohaline circulation between winter and spring."[Wikipedia 1] That caused the spring weather patterns, to continue throughout the season, such patterns being, strong vertical wind shear, mid-level moisture, and strong atmospheric stability.

The strongest storm was Hurricane Humberto, a high-end Category 1 that caused minimal damage, however, the costliest storm was Hurricane Ingrid, another Category 1 that, along with Hurricane Manuel in the Eastern Pacific, caused $5.7 Billion USD, in damages to Mexico. Manuel, caused most of the damage, however, Ingrid was directly responsible for $1.5 Billion USD, in damages.
