The '''2009 Atlantic hurricane season''' is an event in the annual cycle of [[tropical cyclone]] formation. The season officially started on June 1 and will end on November 30. These dates conventionally delimit the period of each year when most tropical cyclones form in the [[Atlantic basin]].

The season began early with the development of [[Tropical Depression One (2009)|Tropical Depression One]] on May 28, but for the next two months the Atlantic basin went dormant. On August 12, [[Tropical Storm Ana (2009)|Tropical Storm Ana]] developed in the vicinity of the Cape Verde Islands, marking the latest date since [[1992 Atlantic hurricane season|1992]] when the season's first tropical cyclone was named in the Atlantic basin.<ref>{{cite web|url=http://www.nhc.noaa.gov/archive/2009/tws/MIATWSAT_jul.shtml?|title=Tropical Weather Summary|author=Avila, Blake|date=2009-08-01|publisher=National Hurricane Center|accessdate=2009-08-02}}</ref> [[Tropical Storm Claudette (2009)|Tropical Storm Claudette]] formed on August 16 and became the first storm of the season to make landfall in the United States early the next morning. [[Hurricane Bill (2009)|Hurricane Bill]] became the first hurricane and first major hurricane of the season. [[Hurricane Fred (2009)|Hurricane Fred]] was unusual as it was the strongest hurricane so far south and east in the NHC's data record, as it reached major hurricane status about thirty-six hours after formation, becoming only the third known major hurricane east of 35°W.

[[File:2009 Atlantic hurricane season summary map.png|thumb|left|Track map of all storms thus far]][[Tropical cyclone seasonal forecasting|Forecasts of hurricane activity]] are issued before each hurricane season by noted hurricane experts Philip J. Klotzbach, [[William M. Gray]], and their associates at [[Colorado State University]]; and separately by [[National Oceanic and Atmospheric Administration|NOAA]] forecasters.

Klotzbach's team (formerly led by Gray) defined the average number of storms per season (1950 to 2000) as 9.6 tropical storms, 5.9 hurricanes, 2.3 major hurricanes (storms reaching at least Category 3 strength in the [[Saffir-Simpson Hurricane Scale]]) and [[Accumulated cyclone energy|ACE Index]] 96.1.<ref name="Gray Dec">{{cite web|author=Philip J.

===Pre-season forecasts===
On December 10, 2008, Klotzbach's team issued its first extended-range forecast for the 2009 season, predicting above-average activity (14 named storms, 7 hurricanes, 3 of Category 3 or higher and [[Accumulated cyclone energy|ACE Index]] of 125). On April 7, 2009, Klotzbach's team issued an updated forecast for the 2009 season, predicting near-average activity (12 named storms, 6 hurricanes, 2 of Category 3 or higher and [[Accumulated cyclone energy|ACE Index]] of 100), citing the possible cause as the high probability of a weak [[El Niño-Southern Oscillation|El Niño]] forming during the season.<ref name="Gray April">{{cite web|author=William M.

===Midseason outlooks===
On June 2, 2009, Klotzbach's team issued another updated forecast for the 2009 season, predicting slightly below average activity (11 named storms, 5 hurricanes, 2 of Category 3 or higher and [[Accumulated cyclone energy|ACE Index]] of 85). On June 18, 2009, the UK [[Met Office]] ([[UKMO]]) issued a forecast of 6 tropical storms in the July to November period with a 70% chance that the number would be in the range 3 to 9. They also predicted an [[Accumulated cyclone energy|ACE Index]] of 60 with a 70% chance that the index would be in the range 40 to 80.<ref name="UKMO June forecast">{{cite web|title=UKMO North Atlantic tropical storms seasonal forecast for 2009| url=http://www.metoffice.gov.uk/weather/tropicalcyclone/northatlantic.html}}</ref> On August 4, 2009, Klotzbach's team updated their forcast for the 2009 season, again predicting slightly below average activity (10 named storms, 4 hurricanes, and 2 major hurricanes). On August 6, 2009, the NOAA also updated their forecast for the 2009 season, predicting below average activity (7-11 named storms, 3-6 hurricanes, and 1-2 major hurricanes).

On May 28, the National Hurricane Center began issuing advisories on Tropical Depression One. The depression had formed about 400 miles (640 km) east-northeast of the [[Outer Banks]] of [[North Carolina]]. With relatively favorable conditions, the depression was forecast to strengthen into a [[tropical storm]] by early May 29 before dissipating over cooler waters shortly thereafter. However, the system did not reach tropical storm strength, and instead began to weaken rapidly later on the 29th.<ref>{{cite web | author=Franklin and Beven | publisher=National Hurricane Center | publisher=National Oceanic and Atmospheric Administration | date=May 28, 2009 | accessdate=2009-05-28 | title=Tropical Depression One Discussion Number 1 | url=http://www.nhc.noaa.gov/archive/2009/al01/al012009.discus.001.shtml?}}</ref> The depression [[extratropical cyclone#Extratropical transition|became extratropical]] at about 5 p.m. [[Atlantic Standard Time|AST]] (2100 [[Coordinated Universal Time|UTC]]) that same day,<ref name="al012009.discus.006">{{cite web | author=Kimberlain and Franklin | publisher=National Hurricane Center | publisher=National Oceanic and Atmospheric Administration | date=May 29, 2009 | accessdate=2009-06-01 | title=Tropical Depression One Discussion Number 6 | url=http://www.nhc.noaa.gov/archive/2009/al01/al012009.discus.006.shtml?}}</ref> and was absorbed by a frontal zone shortly thereafter.

On August 11, Tropical Depression Two developed west of the Cape Verde Islands and was quickly forecasted to become a tropical storm. On August 13, however, exposure to upper level wind shear and dry air led to the storm degenerating into a remnant low. Still, the storm was forecasted to strengthen back into a depression.<ref>http://www.nhc.noaa.gov/archive/2009/al02/al022009.public.011.shtml?</ref> The system's remnants did in fact regenerate into a tropical depression shortly after midnight. Just hours later the depression was upgraded into Tropical Storm Ana and tropical storm watches were issued for most of the [[Leeward Islands]].<ref>http://www.nhc.noaa.gov/archive/2009/al02/al022009.public.018.shtml?</ref> On August 16, Ana degenerated into a Tropical Depression again after an Air Force hurricane hunter aircraft found the storm to be very poorly organized and even further dissipation was predicted.<ref>http://www.nhc.noaa.gov/archive/2009/al02/al022009.public.019.shtml?</ref> Overnight, Ana moved across the Leeward Islands with little change in intensity predicted. The storm was forecasted to track across the northeastern Caribbean Sea and approach [[Hispaniola]] by August 17. Dry air and moderate shear took their toll on Ana, and it dissipated over the northern Caribbean that day. Tropical Storm Ana was one of three tropical storms active on August 16.

Late on August 12, a strong tropical wave associated with an area of low pressure moved off the African coast with deep layers of moisture observed.<ref>{{cite web|author=Walton|publisher=National Hurricane Center|date=2009-08-13|accessdate=2009-08-16|title=Tropical weather discussion 205 AM EDT August 13 2009|url=http://www.nhc.noaa.gov/archive/text/TWDAT/TWDAT.200908130527.txt|archiveurl=http://www.webcitation.org/5jD3PsAZU|archivedate=2009-08-22|deadurl=no}}</ref> Later that day, the wave became better organized with a low level circulation forming, but without any significant convection. That night, the area of convection became more concentrated, but wind shear increased since the previous advisory. On August 14, the disturbance strengthened more and its convective bands became stronger with better circulation, indicating that the disturbance would soon become a tropical depression. Later, on August 15, even though some of its deep convection dissipated, it was officially named Bill, the second named storm of the 2009 season. Early on August 17, an eye appeared on visible and infrared loops and Bill strengthened into a hurricane, the first of the 2009 season. Bill then briefly underwent an eyewall replacement cycle, as the eye had contracted to a half its original size. However, strengthening continued and, on the evening of August 18, Bill rapidly strengthened into a major hurricane. Bill was one of three tropical storms active on August 16. It lost tropical characteristics after making landfall on [[Newfoundland (island)|Newfoundland]] as a weakening Category 1 hurricane on [[August 24]]. The extratropical storm then raced eastward in the Atlantic, in open waters of the North Atlantic and later affected the United Kingdom.

Tropical Storm Claudette formed as the fourth depression of the season in the eastern [[Gulf of Mexico]] on August 16. The disturbance developed rapidly and formation was not expected until just a few hours before its declaration as a tropical depression. As recently as nine hours before the storm's formation, the NHC gave the system a less than 30% chance of developing in the next 48 hours.<ref>[http://www.nhc.noaa.gov/archive/gtwo/atl/200908160247/index.php?basin=atl&current_issuance=200908160247 Tropical Weather Outlook 800 PM EDT August 15, 2009].[[National Hurricane Center]], Avila and Kimberlain (August 15, 2009).

Early on August 17, Claudette made landfall at the east end of Santa Rosa Island, Florida, with 50 mph winds. Later that day, the NHC issued its last public advisory on Claudette as it moved inland and weakened to a tropical depression. Advisories were continued by the [[Hydrometeorological Prediction Center]]. Tropical Storm Claudette was one of three tropical storms active on August 16.

Tropical Storm Erika formed on [[September 1]] at 5 p.m. AST northeast of the Leeward Islands from a low pressure area that had formed from a tropical wave south-southeast of Cape Verde on August 26. The wave moved across the Atlantic, and weakened to low potential for formation, but, the wave reorganized to medium potential, then high potential. Finally, around midday on September 1, the NHC initiated advisories on Tropical Storm Erika, skipping depression status; the second storm of the year to do so. Erika strengthened to a peak of 60 mph late on September 1, but began to weaken early the next day. On September 3, Erika was degraded to a tropical depression and later became a remnant low.

Tropical Depression Seven formed from a tropical wave south of [[Cape Verde]] on [[September 7]]. It strengthened later that day to become Tropical Storm Fred. Early the next day, under favorable conditions, Fred strengthened to a Category 1 hurricane and was expected to intensify further. Fred [[rapid deepening|rapidly intensified]] through the evening and into the early morning hours, becoming a Category 2 hurricane just six hours after becoming a hurricane. It continued to strengthen into a second major hurricane that morning, becoming the strongest storm ever recorded so far south and east in the Atlantic basin in the satellite era, and only the third major hurricane on record east of 35°W.<ref name="FredDisc8">[http://www.nhc.noaa.gov/archive/2009/al07/al072009.discus.008.shtml HURRICANE FRED DISCUSSION NUMBER 8], [[National Hurricane Center]], 1100 AM AST WED SEP 09 2009.

The table on the right shows the [[Accumulated Cyclone Energy|ACE]] for each storm in the season. ACE is, broadly speaking, a measure of the power of the hurricane multiplied by the length of time it existed, so storms that last a long time as well as particularly strong hurricanes have high ACEs. ACE is only officially released for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength.

==Storm names==
The following names will be used for named storms that form in the North Atlantic in 2009. Retired names, if any, will be announced by the [[World Meteorological Organization]] in the spring of 2010. The names not retired from this list will be used again in the 2015 season. Names that were not used are marked in {{tcname unused}}, and names in '''bold''' are storms currently active. This is the same list used in the [[2003 Atlantic hurricane season|2003 season]] with the exception of Fred, Ida, and Joaquin, which replaced [[Hurricane Fabian|Fabian]], [[Hurricane Isabel|Isabel]], and [[Hurricane Juan|Juan]] respectively. If there are more than 21 named storms (the 21st being Wanda) then any more tropical storm-strength systems will be named with the [[Greek alphabet]], starting with Alpha. This has only occurred once, in [[2005 Atlantic hurricane season|2005]]. The name Fred was used for an Atlantic storm the first time in 2009.

==Season effects==
This is a table of the storms in 2009 and their landfall(s), if any. Deaths in parentheses are additional and indirect (an example of an indirect death would be a traffic accident), but are still storm-related. Damage and deaths include totals while the storm was extratropical or a wave or low.
