The 2009 Atlantic hurricane season was a below-average year, unlike the 2009 Pacific hurricane season, which was above average, both due to a moderate El Niño. During this year, nine tropical storms formed, the fewest since the 1997 season.[1][nb 1] Although Tropical Depression One formed on May 28, the season officially began on June 1, 2009 and ended on November 30.[2][3] The season's last storm, Hurricane Ida dissipated on November 10.[4] The season had eleven tropical depressions, of which nine intensified into tropical storms, three became hurricanes, and two became major hurricanes.[nb 2] The inactivity throughout the basin was linked to the formation of an El Niño, which increased wind shear.[1] The two most significant storms of the season, in terms of loss of life and damage, were Hurricanes Bill and Ida. Hurricane Bill was an unusually large storm and was also the season's strongest, attaining winds of 135 mph (215 km/h).[5] Tropical Storm Claudette was the only storm during 2009 to make landfall in the United States, near Pensacola Beach, Florida.[6]

Throughout the basin, six people were killed in tropical cyclone-related incidents and total losses reached roughly $77 million. Of the season's eleven cyclones, five made landfall during their existence. Hurricane Bill caused moderate coastal damage across the eastern United States before brushing Nova Scotia and making landfall in Newfoundland. Significant damage took place in Atlantic Canada as a result of Bill as well. The only storm to make landfall as a tropical cyclone in the United States, Tropical Storm Claudette, caused minor wind and water damage during its brief life in the eastern Gulf of Mexico. In combination with a stronger extratropical system, Tropical Storm Danny caused roughly $25 million in damage throughout Nova Scotia and Newfoundland. In early September, Tropical Storm Erika passed over the island of Guadeloupe, producing moderate rainfall but little damage. Hurricane Ida was the only storm of the season to make landfall at hurricane intensity, crossing the Nicaraguan coastline with winds of 80 mph (130 km/h).

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 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 ACE Index 96.1.[7] NOAA defines a season as above-normal, near-normal or below-normal by a combination of the number of named storms, the number reaching hurricane strength, the number reaching major hurricane strength and ACE Index.[8]

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 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 ACE Index of 100), citing the possible cause as the high probability of a weak El Niño forming during the season.[9] On May 21, 2009, NOAA issued their forecast for the season, predicting near or slightly above average activity, (9 to 14 named storms, 4 to 7 hurricanes, and 1 to 3 of Category 3 or higher).[10]

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 ACE Index of 85). Also on June 2, 2009, the Florida State University Center for Ocean-Atmospheric Prediction Studies (FSU COAPS) issued its first ever Atlantic hurricane season forecast. The FSU COAPS forecast predicted 8 named storms, including 4 hurricanes, and an ACE Index of 65.[11] 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 ACE Index of 60 with a 70% chance that the index would be in the range 40 to 80.[12] On August 4, 2009, Klotzbach's team updated their forecast 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).[13]

During the 2009 season, nine of the eleven tropical cyclones affected land, of which five actually made landfall. The United States experienced one of its quietest years, with no hurricanes making landfall in the country. Throughout the basin, six people were killed in tropical cyclone-related incidents and total losses reached roughly $77 million. Most of the damage resulted from Hurricane Bill, which caused severe beach erosion throughout the east coast of the United States. In the United States, tropical cyclones killed six people and caused roughly $50 million in damage. In the Lesser Antilles, Tropical Storms Ana and Erika brought moderate rainfall to several islands but resulted in little damage. Elsewhere in the Atlantic, the Azores Islands, Atlantic Canada, Bermuda, Cape Verde Islands and Wales were affected by tropical cyclones or their remnants.[1] In Canada, Hurricane Bill produced widespread moderate rainfall in Nova Scotia and Newfoundland, leaving roughly $10 million in losses.[14] The hurricane also produced tropical storm-force winds in Bermuda.[5] Hurricane Fred briefly impacted the southern Cape Verde Islands as it bypassed the islands early in its existence.[15] The Azores and Wales were also affected by Tropical Storm Grace; however, both areas recorded only minor effects.[16]

In addition to the eleven tropical cyclones, there were two other systems that nearly developed into tropical cyclones. In mid-May, a tropical disturbance developed over the Caribbean Sea. The system initially tracked north before turning westward into the Gulf of Mexico.[17] On May 22, a Hurricane Hunter reconnaissance aircraft flew into the system to determine whether or not it had developed into a tropical depression.[18] Hours before moving over the United States Gulf Coast, the NHC stated that the system was likely to become a tropical cyclone;[19] however, this development did not take place, although sustained winds reached 35 mph (55 km/h) at its strongest.[17] The low made landfall near the Alabama-Mississippi border midday on May 22 before dissipating over land.[17][20]

Several hours after Tropical Depression One formed, satellites began monitoring a new low pressure system over the central-north Atlantic. Initially extratropical, the storm gradually became better organized as it tracked westward. Late on June 1, the cyclone had begun to acquire subtropical characteristics, and sustained winds reached 40 mph (65 km/h). The following day, the low attained an intensity with winds of 50 mph (85 km/h) and a barometric pressure of 995 mbar (hPa; 29.38 inHg). Shortly thereafter, the system turned eastward and weakened. It eventually lost its hybrid characteristics on June 4 before losing its identity north of the Azores on June 5. Although the NHC classified the system as a non-tropical low, there was a possibility for the cyclone to be reclassified as a subtropical storm during post-season analysis; however, this did not occur.[21]

Overall, the season's activity was reflected with a low cumulative accumulated cyclone energy (ACE) rating of 53, the lowest since 1997.[22] Due to the low number of storms in the 2009 season, many of which were short-lived, the overall ACE value was ranked as below-average, totaling under 66.[23] Hurricane Bill was responsible for the ACE value for August being 30% above average.[24] 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 calculated for full advisories on tropical systems at or exceeding 34 knots (39 mph, 63 km/h) or tropical storm strength. Subtropical cyclones are excluded from the total.[25]

Storms

Tropical Depression One

Tropical depression (SSHWS)
 
DurationMay 28 – May 30
Peak intensity35 mph (55 km/h) (1-min);
1006 mbar (hPa)

During mid-May, a frontal boundary stalled near The Bahamas and slowly degenerated. On May 25, 2009, an area of low pressure developed along the tail-end of a decaying cold front near the northern Bahamas. Tracking northward, this low gradually developed as it moved within 85 mi (140 km) of North Carolina's Outer Banks. By May 28, deep convection developed across a small area over the low pressure system, leading to the National Hurricane Center classifying the system as Tropical Depression One. The depression moved over the warm waters of the Gulf Stream for the following 24 hours, allowing it to maintain its convection, before moving into a hostile environment characterized by strong wind shear and cooler waters. Late on May 29, the system degenerated into a remnant low. Several hours later, on May 30, about 345 mi (555 km) south-southeast of Halifax, Nova Scotia, Tropical Depression One was absorbed by a warm front.[3]

As a tropical cyclone, the depression had no impact on land. However, the precursor to the system brought scattered rainfall and increased winds to parts of the North Carolina coastline, but no damage[3] Upon becoming a tropical depression on May 28, Tropical Depression One became the northernmost forming May tropical cyclone in Atlantic history. It also marked the third consecutive year with pre-season tropical or subtropical cyclones in the basin.[3][26]

Tropical Storm Ana

Tropical storm (SSHWS)
 
DurationAugust 11 – August 16
Peak intensity40 mph (65 km/h) (1-min);
1003 mbar (hPa)

Ana formed out of an area of low pressure associated with a tropical wave on August 11, Ana briefly attained tropical storm intensity on August 12 before weakening back to a depression. The following day, the system degenerated into a non-convective remnant low as it tracked westward. On August 14, the depression regenerated roughly 1,075 mi (1,735 km) east of the Leeward Islands. Early on August 15, the storm re-attained tropical storm status, at which time it was named Ana. After reaching a peak intensity with winds of 40 mph (65 km/h) and a barometric pressure of 1003 mbar (hPa; 29.65 inHg), the storm began to weaken again due to increasing wind shear and the unusually fast movement of Ana. In post-storm analysis, it was discovered that Ana had degenerated into a tropical wave once more on August 16, before reaching any landmasses.[27]

Numerous tropical storm watches were issued for the Lesser Antilles, Puerto Rico and the Dominican Republic between August 15 and 17..[27] Several islands took minor precautions for the storm, including St. Croix which evacuated 40 residents from flood-prone areas ahead of the storm.[28] In the Dominican Republic, officials took preparations by setting up relief agencies and setting up shelters.[29] Impact from Ana was minimal, mainly consisting of light to moderate rainfall.[27] In Puerto Rico, up to 2.76 in (70 mm),[30] causing street flooding and forcing the evacuation of three schools. High winds associated with the storm also downed trees and power lines, leaving roughly 6,000 residents without power.[31]

Hurricane Bill

Category 4 hurricane (SSHWS)
 
DurationAugust 15 – August 24
Peak intensity135 mph (215 km/h) (1-min);
943 mbar (hPa)

As Ana regenerated into a tropical depression,[27] a new tropical depression developed early on August 15 southwest of the Cape Verde Islands. Light wind shear and warm waters allowed the depression to steadily intensify, becoming Tropical Storm Bill later that day. By August 17, Bill attained hurricane-status about midway between the Cape Verde Islands and the Lesser Antilles. Eventually the hurricane attained its peak intensity as a Category 4 storm roughly 345 mi (555 km) east-northeast of the Leeward Islands. The storm attained maximum winds of 135 mph (215 km/h), the highest of any storm during the season, before weakening slightly as it turned north. The large storm passed roughly 175 mi (280 km) west of Bermuda as a Category 2 hurricane. Further weakening took place as Bill brushed the southern coast of Nova Scotia the following day. Shortly before making landfall in Newfoundland, Bill weakened to a tropical storm and accelerated. The storm eventually transitioned into an extratropical cyclone after moving over the north Atlantic before being absorbed by a larger non-tropical low on August 24.[5]

Two people were killed by the storm's large swells, one in Maine and another in Florida. The hurricane came close enough to warrant tropical cyclone watches and warnings in both the US and Canada. Bill was one of three tropical storms active on August 16.[5] Large, life-threatening swells produced by the storm impacted north-facing coastlines of Puerto Rico and Hispaniola as Hurricane Bill approached Bermuda.[32] Along the coasts of North Carolina, waves averaging 10 ft (3.0 m) in height impacted beaches. On Long Island, beach damage was severe; in some areas the damage was the worst since Hurricane Gloria in 1985.[33] In New York, severe beach erosion caused by the storm resulted in over $35.5 million in losses.[34]

Tropical Storm Claudette

Tropical storm (SSHWS)
 
DurationAugust 16 – August 18
Peak intensity60 mph (95 km/h) (1-min);
1005 mbar (hPa)

Just one day after the formation of Hurricane Bill, the season's third named storm developed on August 16. Forming out of a tropical wave and an upper-level low pressure system, Claudette quickly intensified into a tropical storm offshore south of Tallahassee, Florida. By the afternoon, the storm had attained winds of 60 mph (95 km/h) and steadily tracked towards the Florida Panhandle. Early on August 17, the center of Claudette made landfall on Santa Rosa Island. Several hours after landfall, the storm weakened to a tropical depression and the Hydrometeorological Prediction Center took over primary responsibility of the storm. The system quickly dissipated and was last noted over Alabama on August 18.[35]

The National Hurricane Center issued tropical storm warnings for the Florida coastline and residents in some counties were advised to evacuate storm-surge-prone areas.[35][36] Tropical Storm Claudette, produced moderate rainfall across portions of Florida, Georgia, and Alabama between August 16 and 18. Two people were killed offshore amidst rough seas from the storm.[37] An EF-0 tornado spawned by the storm in Cape Coral damaged 11 homes, leaving $103,000 (2009 USD) in damages. Additional damages to coastal property and beaches amounted to $125,000 (2009 USD) as a result of Claudette.[38]

Tropical Storm Danny

Tropical storm (SSHWS)
 
DurationAugust 26 – August 29
Peak intensity60 mph (95 km/h) (1-min);
1006 mbar (hPa)

Around the same time the remnants of Hurricane Bill dissipated over the northern Atlantic,[5] a new tropical storm developed near the Bahamas on August 26. The system, immediately declared Tropical Storm Danny on its first advisory, erratically moved in a general northwestward direction. Danny attained peak winds of 60 mph (95 km/h) before succumbing to high wind shear. After turning northward, the storm weakened and was eventually absorbed by another low pressure system off the east coast of the United States early on August 29.[39] High waves from Danny killed a boy in the Outer Banks.[40]

Tropical Storm Erika

Tropical storm (SSHWS)
 
DurationSeptember 1 – September 3
Peak intensity50 mph (85 km/h) (1-min);
1004 mbar (hPa)

On September 1, the season's fifth named storm, Tropical Storm Erika, formed east of the Lesser Antilles. Upon forming, the storm had attained its peak intensity with winds of 50 mph (85 km/h). Persistent wind shear prevented the system from intensifying and resulted in the storm's convection being completely displaced from the center of circulation by the time it passed over Guadeloupe on September 2. After entering the Caribbean Sea, Erika briefly regained strength before fully succumbing to strong shear. The system eventually dissipated on September 4 south of Puerto Rico.[41] Damages were minor, though one island received several inches of rain.

Hurricane Fred

Category 3 hurricane (SSHWS)
 
DurationSeptember 7 – September 12
Peak intensity120 mph (195 km/h) (1-min);
958 mbar (hPa)

Several days after Erika dissipated,[41] a new tropical depression formed southeast of the Cape Verde Islands on September 7. This depression rapidly intensified within an environment of low wind shear and high sea surface temperatures. Receiving the name Fred on September 8, the storm quickly developed an eye feature and was upgraded to a hurricane roughly 24 hours after being named. Within a 12 hour span, the storm's winds increased by 40 mph (65 km/h) to its peak of 120 mph (195 km/h). Upon reaching this intensity, Fred became the strongest storm on record south of 30°N and east of 35°W in the Atlantic basin. Not long after the intensification ceased, it began to weaken as dry air became entrained within the system. By September 11, the storm nearly stalled northwest of the Cape Verde Islands and weakened to a tropical storm. The following day, Fred degenerated into a remnant low before taking a westward track across the Atlantic. The remnants of Fred persisted for nearly a week, nearly regenerating into a tropical depression several times. The low eventually dissipated on September 19 south of Bermuda.[15]

Tropical Depression Eight

Tropical depression (SSHWS)
 
DurationSeptember 25 – September 26
Peak intensity35 mph (55 km/h) (1-min);
1008 mbar (hPa)

In late September, a new, well-defined tropical wave moved off the west coast of Africa into the Atlantic Ocean. By September 25, the system had developed sufficient deep convection for the NHC to classify it as Tropical Depression Eight. At this time, the depression attained its peak intensity with winds of 35 mph (55 km/h) and a minimum pressure of 1008 mbar (hPa). Shortly thereafter, wind shear and decreasing sea surface temperatures caused the depression to weaken. The system degenerated into a remnant low on September 26 before degenerating into a trough of low pressure.[42]

Tropical Storm Grace

Tropical storm (SSHWS)
 
DurationOctober 4 – October 6
Peak intensity65 mph (100 km/h) (1-min);
986 mbar (hPa)

Originating from an extratropical cyclone east of Newfoundland on September 27, the precursor to Tropical Storm Grace tracked southeastward towards the Azores , gaining subtropical characteristics. After executing a counterclockwise loop between October 1 and 3, deep convection wrapped around a small circulation center that had developed within the larger cyclone. On October 4, this smaller low developed into a tropical storm while situated near the Azores Islands, becoming the northeastern-most forming Atlantic tropical cyclone on record. The storm quickly turned northeastward and intensified, developing an eye-like feature as it attained peak winds of 65 mph (100 km/h) and a minimum pressure of 986 mbar (hPa; 29.11 inHg). It weakened over increasingly colder waters and began merging with an approaching frontal boundary. Early on October 6, Grace transitioned into an extratropical cyclone before dissipating later that day near Wales.[16]

Although Grace passed through the Azores Islands, the storm had little known effects there.[16] In Europe, the system and its remnants brought rain to several countries, including Portugal,[43] the United Kingdom[44] and Belgium.[45] No fatalities were linked to Grace and overall damage was minimal.[16]

Tropical Storm Henri

Tropical storm (SSHWS)
 
DurationOctober 6 – October 8
Peak intensity50 mph (85 km/h) (1-min);
1005 mbar (hPa)

A tropical wave left the coast of Africa on October 1, moving westward with intermittent showers and thunderstorms.[46] On October 5, the system became better organized,[47] and a low pressure area formed.[48] Although the thunderstorms were displaced east of the center of circulation and the probability for development was never high, the disturbance became a tropical depression around 0000 UTC on October 6 about 775 mi (1,247 km) east of the Lesser Antilles.[46] Operationally, the storm was not designated a tropical cyclone until later on October 6, when it was immediately declared a tropical storm.[49]

Affected by strong wind shear, Henri remained disorganized with its center located on the western edge of the convection. Moving northwestward, Henri intensified slightly to peak winds of 50 mph (85 km/h) on October 7 after the convection increased. Shortly thereafter, the wind shear grew stronger, and on October 8 the storm weakened to a tropical depression.[46] The structure became further disorganized with several low-level vortices.[50] Just twelve hours after weakening into a depression, Henri degenerated into a remnant area of low pressure. The remnants continued northwestward before turning to the west-southwest due to a ridge. On October 11, the circulation dissipated near Hispaniola, having never impacted land.[46]

Hurricane Ida

Category 2 hurricane (SSHWS)
 
DurationNovember 4 – November 10
Peak intensity105 mph (165 km/h) (1-min);
975 mbar (hPa)

The final storm of the 2009 season formed over the southern Caribbean Sea on November 4. The slow moving system quickly developed into Tropical Storm Ida within a favorable environment as it neared the coastline of Nicaragua. Several hours before moving over land, Ida attained hurricane-status, with winds reaching 80 mph (130 km/h). Hours after moving inland, Ida weakened to a tropical storm and further to a tropical depression as it turned northward. On November 7, the depression re-entered the Caribbean Sea and quickly intensified. Early on November 8, the system re-attained hurricane intensity as it rapidly intensified over warm waters. Ida attained its peak intensity as a Category 2 hurricane early the next day with winds of 105 mph (165 km/h) as it moved over the Yucatan Channel. Not long after reaching this intensity, Ida quickly weakened to a tropical storm as it entered the Gulf of Mexico. Despite strong wind shear, the storm briefly re-attained hurricane status for a third time near the southeastern Louisiana coastline before quickly weakening to a tropical storm. Shortly before moving inland over the southern United States, Ida transitioned into an extratropical cyclone. The remnants of Ida persisted until November 11, at which time the low dissipated. Remnant energy from Ida provided energy for another system which became a powerful nor'easter, causing significant damage in the Mid-Atlantic States. The resulting storm came to be known as Nor'Ida.[4]

In the southern Caribbean, Hurricane Ida caused roughly $2.1 million in damage in Nicaragua after destroying numerous homes and leaving an estimated 40,000 people homeless.[51][52] Ida also produced significant rainfall across portions of western Cuba, with some areas recording up to 12.5 in (320 mm) of rain during the storm's passage.[4] In the United States, the hurricane and the subsequent nor'easter caused substantial damage, mainly in the Mid-Atlantic States.[4] One person was killed by Ida after drowning in rough seas while six others were killed in various incidents related to the nor'easter. Overall, the two systems caused nearly $300 million in damage throughout the country.[38]

Storm names

The following names were used for named storms in the North Atlantic in 2009. Names that were not used are marked in gray. This is the same list used in the 2003 season with the exception of Fred, Ida, and Joaquin, which replaced Fabian, Isabel, and Juan respectively.[53] The names Fred and Ida were used for Atlantic storms for the first time in 2009.[26] There were no names retired this year; thus, the same list will be used again in the 2015 season.[54]
