Number of storms

The 2005 Atlantic hurricane season, with 28 named storms (wind speed ≥ 39 mph), is the most active season on record, surpassing the 1933 season's 21 named storms. With 15 hurricanes, the 2005 season also has had the most hurricanes form, surpassing the 1969 season's 12. While the 1950 season still holds the record for the most major hurricanes, eight (2005 had seven), the 2005 season has also tied the 1999 season's record of five Category 4 and 5 hurricanes and holds the record for the most Category 5 hurricanes in a single season, four (see below).

With the formation of Tropical Storm Vince, Tropical Storm Wilma, and Tropical Storm Alpha, 2005 became the first season to use the 'V', 'W' and Greek Letter names, respectively, since naming of Atlantic storms began in the 1950 season. It also has the distinction of being only the second season to use the 'R', 'S', and 'T' names. Only the 1995 season had previously used these letters.

2005 holds the record for the most storms to ever form during the month of July. Five storms (Cindy, Dennis, Emily, Franklin, and Gert) formed during that period. The previous record for most storms to form in the month of July was four; this record was held by the 1966 and 1995 seasons.

The number of storms before the end of July (seven) is also a record, breaking the record of five set in the 1887, 1933, 1936, 1959, 1966, and 1995 seasons.

2005 and 1933 share the record for the most storms (17) forming before the end of September. 2005 now also holds the record for most storms (23) forming before the end of October and ties for the number of storms forming during October with 1950, as seven storms (Stan, Unamed Subtropical Storm ,Tammy, Vince, Wilma, Alpha and Beta) formed during that period. 2005 also ties the record for most storms forming in November, with 3 storms (Gamma, Delta and Epsilon); 2001 is the other year with 3.

Total activity

Tropical activity during the 2005 season was unusually continuous from start to finish, unlike most hurricane seasons, which have significant periods of inactivity. Out of the 26 weeks in the hurricane season, just two had no tropical activity, the week of June 19 and the week of November 6. Between June 28 and October 31, the longest lull period was just four and a half days. This means that 2005 saw 19 weeks of near-continuous activity. There was record or near-record activity in every month of the season except for June.

The 2005 season was the first time since reliable measurements began that the Atlantic basin recorded more tropical storms than the Western Pacific typhoon season, which is typically by far the most active basin worldwide.

Statistics

This table gives the number of storms by month of formation and storm category on the Saffir-Simpson Hurricane Scale. The meanings of the one-letter (or number) categories can be ascertained by placing the cursor on that heading.

Entries which are bolded surpassed or tied records established by previous seasons.

Strongest storms

Hurricane Katrina became the fourth most intense Atlantic hurricane on record (currently sixth) when the storm's central pressure dropped to 902 mbar on August 28.

Hurricane Rita became the third most intense Atlantic hurricane (currently fourth) and the most intense hurricane on record in the Gulf of Mexico after reaching a pressure reading of 895 mbar on September 21.

Hurricane Wilma became the most intense Atlantic hurricane in recorded history (but note numerous Pacific typhoons have been more intense) at just before 5:00 am EDT on October 18, when the central pressure was measured at 884 mbar. At 8:00 am EDT, Wilma continued to intensify, reaching 882 mbar. Wilma also holds the record of being the only Category 4 storm in the Atlantic Basin to record a minimum central pressure below 900 mbar with a central pressure of 894 mbar and winds of 155 mph on October 20. Katrina, Rita and Wilma are the three most intense storms ever in a single Atlantic hurricane season.

Hurricane Wilma also underwent the most rapid deepening for a 24-hour period ever measured. At noon on October 18, Wilma had a central pressure of 980 mbar (28.93 inches). At noon on October 19, Wilma had a central pressure of 882 mbar (26.04 inches), a pressure fall of 98 mbar (2.89 inches), breaking the previous record of 92 mbar (2.71 inches) set by Super Typhoon Forrest in the Western Pacific in 1983. Some sources, however, say that Forrest's pressure was lower than originally measured (876 mbar instead of 883 mbar). This fact would imply that Forrest retains the record with a pressure fall of 100 mbar in 24 hours, and thus this uncertainty is noted here.

In addition, Hurricane Dennis and Hurricane Emily, both in July, reached 930 mbar and 929 mbar respectively, becoming the two strongest storms on record in July.

Katrina was also the third most intense hurricane on record to make landfall in the United States in terms of pressure (920 mbar), behind the Labor Day Hurricane of 1935 and Hurricane Camille in 1969.

When Emily reached Category 5 intensity on July 16, it became the earliest Category 5 hurricane ever, shattering the record set by Hurricane Allen in the 1980 season. When Katrina reached Category 5 intensity on August 28, it became only the third time in recorded history (and the first time since the 1961 season) that there had been two Category 5 hurricanes in a single season. When Rita reached Category 5 intensity on September 21, 25 days after Katrina, the 2005 season became the first that had three Category 5 storms. When Wilma became a Category 5 storm on October 19, the 2005 season doubled the record set by the 1960 and 1961 seasons, becoming the first that had four Category 5 storms.

Rapid formation

Almost every storm in 2005 has set a record for early formation. The table shows the dates on which each storm formed, and the old record for earliest-forming storm of that number.

Individual storms

Main article: List of 2005 Atlantic hurricane season storms
Saffir–Simpson scale

The table below describes the characteristics of the individual storms. Included are data on the storms overall and on the landfalls of each. The colors are associated with the Saffir-Simpson scale of hurricane intensities, and are summarized in the table on the right side of this paragraph. (To see a brief description of how an intensity is defined, just place your cursor on the appropriate element of the right-hand table.)

  • The leftmost 6 columns are color coded by storm strength at maximum intensity.
  • The next 3 columns are color coded based on intensity at each landfall.

[Note that even a non-landfalling storm can cause deaths and damage. Tropical cyclones are not point events. Storm related wind, rain and rough surf can be present hundreds of miles away from the center (although the greatest likelihood of storm-related damage and deaths occurs for landfalling storms and at landfall). Also extratropical land effects are not included in the landfall section, although they are included in the estimates for damage and deaths.]

Entries which are bolded are records for the Atlantic basin.

Template:Fnb Achieved by Wilma on 19 October 2005.
Template:Fnb Total damage is still a very uncertain number.
Template:Fnb The toll outside of parentheses includes deaths which had been attributed to Hurricane Stan, but the NHC has asserted that many of the deaths are more attributable to a larger weather pattern instead of Stan itself. It also includes deaths reported to have been related to Hurricane Rita, but not confirmed as such in the TCR.

The table to the right shows the tropical storms of the 2005 season ranked from highest to lowest Accumulated Cyclone Energy (ACE), given to three significant figures. The total for the season was 250 x 104 kt2 which is the highest seasonal ACE value recorded. It is slightly higher than that for 1950 season which had an ACE of 243 x 104 kt2. (It should be noted that the final storm of the season, Zeta, lasted into 2006. In calculating the seasonal ACE, the whole ACE of Zeta, including the contribution made in 2006, was used.)

ACE measures a combination of both the strength and duration of a tropical cyclone, so longer-lasting storms may accumulate more ACE than stronger storms with shorter durations. This discrepancy is most obvious in the comparatively high ACE value of Hurricane Emily to Hurricanes Katrina and Rita: Emily was not as strong as either storm, but formed out in the Atlantic and made a long track across the Caribbean Sea before making landfall. Katrina and Rita, however, both developed in the Bahamas, close to the U.S. mainland, and lasted for much shorter periods of time. In addition, Ophelia and Epsilon are high for their intensity because they maintained themselves for a long period of time and were slow to build and dissipate, as neither was ever more intense than a category 1 storm.

The average ACE per storm in 2005 was actually close to the seasonal average. In comparison with previous seasons with high seasonal ACE values, relatively few strong, long-lasting storms, such as Cape Verde-type hurricanes, formed. Thus, although the number of named storms in 2005 was about 40% greater than that in any season since 1950, the seasonal ACE was only marginally greater than the previous record, set in 1950 itself, when the average ACE per storm was approximately double that of 2005.

Other records

Hurricane Vince was the farthest northeast that a tropical storm has ever formed in the Atlantic basin since records have been kept. It was also the first tropical cyclone on record to make landfall in mainland Europe without becoming extratropical.

Five storm names were retired - Dennis, Katrina, Rita, Stan, and Wilma. This breaks the record of four, previously held by the 1955, 1995, and 2004 Atlantic hurricane seasons.
