NCEI added Alaska climate divisions to its nClimDiv dataset on Friday, March 6, 2015, coincident with the release of the February 2015 monthly monitoring report. For more information on this data, please visit the Alaska Climate Divisions FAQ.
The recent average (1995-2005) seasonal activity in the North
Atlantic basin is 13 named storms, 7.7 hurricanes and 3.6 major
hurricanes. These values represent an increase over the average of
the preceding 25 years (1970-1994) of 8.6 named storms, 5
hurricanes and 1.5 major hurricanes.

2006 season summary:
While the 2006 season did not officially begin until June 1st,
Tropical Storm Zeta, which formed on December 30th, 2005 persisted
until January 5th of this year, making it the first storm of 2006
in the Atlantic basin. However, the first storm of the official
2006 Atlantic hurricane season was Tropical Storm
Alberto, which was named on June 11th off the coast of Cuba.
Alberto made landfall on June 13th near Apalachee Bay, FL, and it's
ACE value was 2.64 x 104 kt2. Since then,
the Atlantic season has been much quieter than had been initially
forecast. Hurricane Gordon became the first major hurricane of the
Atlantic season on September 13th, but did not make landfall. Isaac
was the last named storm during the 2006 season. Prior to its
dissipation in early October, Isaac brushed the Bermuda coast as a
category 1 storm.
For the season, there were 5 hurricanes (2 major) and 4 tropical
storms: a below-average season when compared with the recent
1995-2005 average, yet similar to the average of the preceeding 25
years (1970-1994) listed in the paragraph above. Only 2 storms made
landfall with the mainland U.S. during 2006, Tropical Storm Alberto
in Florida and Hurricane Ernesto as a tropical storm in Florida and
North Carolina. For additional information on individual storms,
please see the summaries below. For statistics on the Atlantic
storm season, please see NCDC's 2006 Atlantic basin
Tropical Cyclone page.
The average seasonal activity in the East Pacific Basin is 16 named
storms, 9 hurricanes and 4 major hurricanes.

|2006 season summary:
Nineteen named storms formed in the East Pacific Hurricane basin
during the 2006 season, which is above average. Eleven of these
storms were classified as hurricanes and 6 storms were major
hurricanes (category 3-5 on the Saffir-Simpson Scale). Perhaps
the most notable hurricane of the season was Ioke, which became a
category 5 hurricane on August 26th. Ioke crossed the International
Date Line into the western Pacific, the first category 5 storm to
do this since 1994. Super Typhoon Ioke continued on a westerly
track before weakening. For more information on Ioke, see the
August summary below.
Three tropical storms made landfall in Mexico during the 2006
season. John was a category 2 storm when it came ashore near the
southern tip of the Baja Peninsula in August. Hurricane Lane was
the strongest storm to make landfall in the East Pacific during the
2006 season. This storm was a category 3 when it hit land in the
Sinaloa State of Mexico in mid-September. Hurricane John came
ashore as a tropical depression in October also in Sinaloa.
In November, Tropical Storm Rosa and Hurricane Sergio formed: the
first time since the 1961 season two named storms formed in
November in the East North Pacific basin. Sergio strengthened into
a strong category 2 storm and became the strongest hurricane to
form or exist in this basin during the month of November. For
additional information on these and all the 2006 season storms, see
the summaries below.
