Talk about a very active season we had. It is one of the most active seasons we have seen with records going to back to 1851. Here is how 2010 Hurricane Season compares with other seasons. This goes back to 1870.

Total Number
2005-28
1933-21
1887/1995/2010-19

2010 season ties with 1995 and 1887. However, I think 1887 Hurricane Season had more storms recorded because there were no satellites back than. Also, hurricane encounters were by ship and they try to avoid hurricanes for obvious reason.

Hurricanes
2005-15
1969/2010-12

In term of number of hurricanes, 2010 ties with 1969 Hurricane Season. Only 2005 beats 2010. However, I think there have been season with more hurricanes than recorded in the past.

Major Hurricanes
1950-8
1961/2005-7
1926/1955/1964/1996/2004-6
1893/1916/1933/1951/1958/1969/1995/1999/2008/2010-5

2010 Hurricane Season ties with various years with 5 major hurricanes. The most recent being 2008. All of them formed in a one month period from August to September.

Accumulated Cyclone Energy (ACE)
2005-248
1950-243
1893-231
1995-227
2004-224
1926-222
1933-213
1961-205
1955-199
1887/1998-182
1878-181
1999-177
2003-175
1964-170
1886/1996-166
1906-163
2010-160*

*-Preliminary

ACE is used to measure energy used by a tropical cyclone in its lifetime. The stronger and longer lived a tropical cyclone is, the higher the ACE is. In addition, higher the ACE, the more active the season will be.

The 2010 Hurricane Season is the 17th most active in terms of ACE from 1870 to 2010. This is preliminary before NHC releases their final report for all the storm. I think there is a good chance the ACE for 2010 will go up. It ties with 1906 Hurricane Season based on Best Track, in which the storm is tracked in 6 hour intervals for HURRDAT. Any new data will be updated in the future.

America was very lucky with the 2010 Hurricane Season. Tropical Storm Bonnie made landfall on South Florida. Tropical Storm Hermine hit Texas with tropical storm force wind and heavy rain even though it made landfall in Mexico.
