List of storms in the 2007 Atlantic hurricane season

The 2007 Atlantic hurricane season was an event in the annual cycle of tropical cyclone formation. It officially started June 1, 2007, and ended November 30, 2007, dates that conventionally delimit the period when most tropical cyclones form in the Atlantic basin during the year. However, the formation of Subtropical Storm Andrea on May 9, 2007 marked an earlier beginning to the season, and the season extended past the official end of the season when Tropical Storm Olga developed on December 11. The 2007 season was fairly active, with 15 named storms, though the intensities of the storms did not meet the predictions.hurricane season related|season=2007 Atlantic hurricane|list=yes

ubtropical Storm Andrea

Infobox Hurricane Small

Track=Andrea 2007 track.pngFormed=May 9
Dissipated=May 11
1-min winds=50
A large extratropical cyclone that formed off the mid-Atlantic coast on May 6 deepened steadily along a cold front that pushed through Florida. When the system lost most of its baroclinic support, development ceased until its low moved into warmer waters near the Bahamas. However, interaction between the low and a strong high-pressure system to the north generated hurricane-force winds in the system. Decreasing vertical wind shear allowed the storm to generate deeper convection much closer to the center.cite web|url=|title=Tropical Cyclone Report for Subtropical Storm Andrea|accessdate=2007-11-29|author=|Jaime R. Rhome|coauthors=Jack Bevin; Mark Willis|date=2007-06-01|publisher=National Hurricane Center] By May 9 the previously extratropical cyclone had transformed into Subtropical Storm Andrea while located about 140 miles (225 km) southeast of Savannah, Georgia.cite web|url=|title=Subtropical Storm Andrea Advisory 1|accessdate=2007-11-30|author=Knabb|date=2007-05-09|publisher=National Hurricane Center]

Tropical storm watches were immediately issued for parts of coastal Georgia and Florida, though all were later dropped. Andrea was the first named storm to form in May since Arlene in 1981, and the first pre-season storm since Ana in April 2003.cite web|url=|title=Storms & Hurricanes in the off season|accessdate=2007-11-30|author=Unisys|publisher=Hurricane City] Andrea began its subtropical phase as it was weakening, and continued this deterioration as it moved southward into an environment with higher wind shear. By May 11 Andrea had lost all significant convection and degenerated into a remnant low. Though it produced intermittent bursts of convection, Andrea's chance of regeneration was extinguished when an advancing cold front pushed it northward and eventually absorbed the system.

The storm produced rough surf and large waves along the coastline from Florida to North Carolina, causing beach erosion and some damage.cite web|url=|title=Special Tropical Disturbance Statement for May 9|publisher=National Hurricane Center|accessdate=2007-05-09|author=Brown|date=2007-05-08] No deaths were directly attributable to Andrea, though six people died from the waves generated during its extratropical phase. The storm was also blamed for high winds that could have fueled severe wildfires in northern Florida and southern Georgia.cite news|url=,0,3010146.story?coll=orl-news-headlines-state|title='Fire of a lifetime' hits North Florida|accessdate=2007-05-13|author=Kevin Spear and Jim Stratton|date=2007-05-12|publisher=Orlando Sentinel] However, because Andrea never made landfall, most of the resulting damage was associated with large waves, higher than normal tides, associated coastal flooding, and beach erosion caused by the storm.

Tropical Storm Barry

Infobox Hurricane Small

Track=Barry 2007 track.pngFormed=June 1
Dissipated=June 2
1-min winds=50
On May 30, a broad low pressure area formed in the Gulf of Honduras. Moving northward, the system slowly deepened as it moved through the northwest Caribbean Sea and into the southeast Gulf of Mexico. On June 1, the first day of the officially defined hurricane season, this cyclone organized into Tropical Storm Barry despite being located in an area of high shear, and warnings were immediately issued along the western Florida coastline. Barry provided much-needed precipitation to parts of Florida and Georgia, which were experiencing drought conditions. [ [ Drought Information Statement - National Weather Service Tallahassee, FL] ] Barry made landfall near Tampa Bay, Florida on June 2 as a minimal tropical storm. Soon thereafter Barry was downgraded to a tropical depression as it began its extratropical transition. Barry became an extratropical cyclone late in the afternoon of June 2. On June 3, the cyclone moved up the coast of the Carolinas bringing rains into the Mid-Atlantic states and New England. By June 5 its center had moved northward into Atlantic Canada.

Tropical Storm Chantal

Infobox Hurricane Small

Track=Chantal 2007 track.pngFormed=July 30
Dissipated=August 1
1-min winds=45
An area of low pressure developed near the Bahamas on July 28, and slowly organized while moving to the north-northeast. Late on July 30, it was upgraded to a tropical depression, the third of the season, after maintaining deep convection near the center for most of the day.

On July 31, the system strengthened into a tropical storm south of Nova Scotia, the first in nearly two months. However, Chantal became extratropical later that day as it tracked towards Newfoundland over the cooler waters of the north Atlantic.

On August 1, flooding was reported from Placentia to the capital city of St. John's, where about 100 mm (4 inches) of rain caused the postponement of the annual Royal St. John's Regatta. Up to 150 mm (6 inches) of rain fell in the Whitbourne area, according to Environment Canada. [ [ | News | Storm pummels Newfoundland ] ] The most serious flooding was across the southern Avalon Peninsula, where dozens of roads were washed out, houses were flooded above their basements and several communities were isolated. [ [ Chantal leaves 'havoc' behind in Newfoundland ] ] Ferry service between Argentia and North Sydney, Nova Scotia, was suspended, and one ferry was diverted to Port aux Basques. [] ]

States of emergency were declared in at least five communities in the areas surrounding Placentia Bay and Conception Bay, and the Newfoundland and Labrador Municipal Affairs Minister Jack Byrne requested a federal disaster area declaration. Damage is estimated to be well into the millions of dollars, with at least $4 million in damage in the town of Placentia alone.

1-min winds=150
A vigorous tropical wave moved off the west coast of Africa in the second week of August. It quickly organized itself and formed into a low on August 12. Tropical Depression Four formed on August 13 in the eastern Atlantic from a tropical wave to the south of Cape Verde. The depression was already exhibiting persistent deep convection, albeit confined to the western portion of its circulation due to easterly wind shear.cite web|author=Knabb|year=2007|title=Tropical Depression Four Discussion One|publisher=National Hurricane Center|accessdate=2007-08-14|url=] The depression was expected to strengthen significantly over the following days due to abating wind shear and warming sea surface temperatures which created conditions favorable for tropical intensification.cite web|author=Knabb|year=2007|title=Tropical Depression Four Discussion Two|publisher=National Hurricane Center|accessdate=2007-08-14|url=] The depression moved briskly westward, south of a deep layered ridge,cite web|author=Brown/Franklin|year=2007|title=Tropical Depression Four Discussion Three|publisher=National Hurricane Center|accessdate=2007-08-14|url=] quickly escaping the easterly shear.cite web|author=Rhome|year=2007|title=Tropical Depression Four Discussion Four|publisher=National Hurricane Center|accessdate=2007-08-14|url=]

Dean weakened to a category one storm over land.

At least 42 people have been killed by Hurricane Dean (see Impact of Hurricane Dean). None of these deaths, however, have been attributed to its first landfall, as a Category 5 hurricane, likely because the landfall brought the heaviest storm surges onto sparsely-populated lands north of Chetumal Bay, including the Sian Ka'an Biosphere Reserve.

On August 31, an area of disturbed weather east of the Windward Islands was numbered Tropical Depression Six after satellite imagery showed that a tropical low had formed.cite web|author=Blake/Avila|date=2007-08-31|title=Tropical Depression Six Public Advisory One|publisher=National Hurricane Center|accessdate=2007-08-31|url=] Early on September 1, it was upgraded to a tropical storm and named Felix. Later that day, Felix was upgraded to a hurricane. On September 2, Felix was upgraded to a major hurricane. It rapidly intensified into a Category 5 storm by the end of the evening, and after briefly weakening to Category 4 status Felix again restrengthened and struck northeastern Nicaragua with winds of 160 mph (260 km/h) on September 4. (See Impact of Hurricane Felix). It rapidly weakened over land and the last advisory was issued on September 5. At least 133 people were killed by Hurricane Felix with another 70 others missing.

Tropical Storm Gabrielle

Infobox Hurricane Small

Track=Gabrielle 2007 track.pngFormed=September 8
Dissipated=September 11
1-min winds=50
A cold front that moved off the southeastern coast of the United States on September 1 developed a weak low over the waters near Georgia. The low drifted eastward and weakened over the next few days until it joined with convection from an upper-level trough that had been moving over the western Atlantic.cite web|url=|title=Tropical Cyclone Report for Tropical Storm Gabrielle|accessdate=2007-10-30|author=Daniel P. Brown|date=2007-10-29|publisher=National Hurricane Center] An Air Force Reserve Hurricane Hunter investigating the low on September 7 was unable to find a well-defined circulation, but did find evidence of tropical storm-force surface winds. Subsequent satellite imagery from that evening discovered a broad and elongated low, indicating that Subtropical Storm Gabrielle had formed about convert|360|nmi|km southeast of Cape Hatteras.cite web|url=|title=Subtropical Storm Gabrielle Discussion 1|accessdate=2007-10-30|author=Beven/Roberts|date=2007-09-07|publisher=National Hurricane Center]

For the next twelve hours, the system's strongest winds and thunderstorms remained well to the north of the center. On September 8 new convection eventually united with the center, leading the transition of Gabrielle into a tropical storm. Gabrielle gradually strengthened as it travelled northwest towards North Carolina and Virginia. The storm reached its peak intensity of 60 mph (95 km/h) just before it arrived in Cape Lookout, though strong wind shear kept most of the convection and surface winds offshore. Gabrielle weakened over land, and moved back into the Atlantic on September 10. The circulation deteriorated further, and the storm dissipated southwest of Nova Scotia the next day.cite web|url=|title=Subtropical Storm Gabrielle Discussion 16|accessdate=2007-10-30|author=Brown|date=2007-09-11|publisher=National Hurricane Center] Damages in eastern North Carolina were very light, and there were no casualties associated with this system.

Tropical Storm Ingrid

Infobox Hurricane Small

Track=Ingrid 2007 track.pngFormed=September 12
Dissipated=September 17
1-min winds=40
A large, westward-moving tropical wave moved off the coast of Africa on September 6. Strong easterly shear inhibited its development until the 9th, when it developed a broad area of low pressure in the mid-tropical Atlantic.cite web|author=National Hurricane Center|year=2007|title=Tropical Cyclone Report for Tropical Storm Ingrid|accessdate=2007-10-18|url=] By the morning of September 12, the shear had weakened, allowing the system to organize into Tropical Depression Eight about convert|980|nmi|km east of the Lesser Antilles.

The depression moved west-nortwestward for the next week, steering along the southern edge of a mid-tropospheric ridge. Unfavorable conditions caused by moderate westerly shear inhibited the storm's initial development. Despite this, the cyclone slowly developed into a weak tropical storm on September 13, and reached its maximum intensity the next day. The shearing winds from a tropical upper tropospheric trough persisted over the cyclone, returning Ingrid to a depression on September 15. The final advisory was issued on the 17th as the system degenerated into an open wave north of the Leeward Islands.cite web|author=Franklin|year=2007|title=Tropical Storm Ingrid Advisory Twenty|publisher=National Hurricane Center|accessdate=2007-10-18|url=] There were no reports of damage or casualties associated with Ingrid because the storm never threatened land.

Track=10-L 2007 track.pngFormed=September 21
Dissipated=September 22
1-min winds=30
An extratropical low formed off the east coast of Florida on September 18. It slowly tracked westward, breaking itself away from a trough over the Atlantic while crossing the Florida Peninsula on September 19, emerging in the Gulf of Mexico on September 20. It slowly organized itself and was classified as a subtropical depression on the morning of September 21 just south of the Florida Panhandle. Three hours later, it was reclassified as fully tropical. At 8 pm EDT (0000 UTC) later that day, Tropical Depression Ten began to move onshore, and never reached tropical storm strength.

Damage from the precursor low was reported in Eustis, Florida from one or more tornadoes that damaged or destroyed about 50 houses, but caused no serious injuries. [ [,0,1891646.story?track=rss Topic Galleries - ] ] No deaths were reported from the tornado, and damage totaled $6.2 million.

Tropical Storm Jerry

Infobox Hurricane Small

Track=Jerry 2007 track.pngFormed=September 23
Dissipated=September 24
1-min winds=35
Jerry's origins can be traced back to a non-tropical low pressure area over the central Atlantic on September 21. Late the next day, it had been determined that a subtropical depression had formed, as a warm core had developed but the system was still involved with an upper-level low, and its strongest winds were well removed from the center.cite web|url=|title=Tropical Cyclone Report for Tropical Storm Jerry|accessdate=2007-11-09|author=Lixion A.

Hurricane Karen

Infobox Hurricane Small

Track=Karen 2007 track.pngFormed=September 25
Dissipated=September 29
1-min winds=65
A very large tropical wave accompanied by a large envelope of low pressure emerged from the coast of Africa on September 21. As it moved westward, deep convection gradually increased over the disturbance as its broad low-level circulation became better-defined. By September 24, as the system traveled northwestward it organized enough to become a tropical depression.cite web|url=|title=Tropical Cyclone Report for Hurricane Karen|accessdate=2007-11-27|author=Richard J. Pasch|date=2007-11-21|publisher=National Hurricane Center] Six hours later the depression was upgraded to Tropical Storm Karen.cite web|url=|title=Tropical Storm Karen Discussion 2|accessdate=2007-11-27|author=Bevin|date=2007-09-25|publisher=National Hurricane Center]

Karen's organization and intensity remained steady for the next day. Early on the 26th, however, the storm strengthened significantly. In post-operational analysis the cyclone was determined to have reached hurricane-strength for about twelve hours. The strengthening was short-lived because a sharp upper-level trough to the west of Karen increased the amount of vertical wind shear over the hurricane. By September 28 these unfavorable conditions had weakened Karen to a marginal tropical storm and left its low-level circulation exposed.cite web|url=|title=Tropical Storm Karen Discussion 14|accessdate=2007-11-27|author=Mainelli|date=2007-09-28|publisher=National Hurricane Center] Meanwhile, the storm began heading northward and experiencing intermittent bursts of deep convection. However, the relentless wind shear exposed the system's circulation until it dissipated in the mid-Atlantic on September 29. Karen's remnants lingered near the Leeward Islands for the next few days, although the system never directly affected land. As a result, no reported damages or casualties were associated with Karen.

1-min winds=70
A tropical wave moved off the western coast of Africa on September 11,cite web|author=National Hurricane Center|year=2007|title=Tropical Cyclone Report for Hurricane Lorenzo|accessdate=2007-10-19|url=] traversed the Caribbean and crossed the Yucatán on September 21. The disturbance developed a small surface low on the 24th while moving erratically over the southwestern Gulf of Mexico. Strong upper-level winds initially prevented the system from developing convection; however, it relaxed on the following day and convection increased.cite web|author=Franklin and Brown|year=2007|title=September 24 5:30 p.m. Tropical Weather Outlook|publisher=National Hurricane Center|accessdate=2007-09-26|url=] On the evening of September 25, a Hurricane Hunter aircraft found evidence that the low qualified as a tropical depression.cite web|author=Franklin|year=2007|title=Tropical Depression Thirteen Discussion 1|publisher=National Hurricane Center|accessdate=2007-09-26|url=]

Under weak steering currents, the depression drifted south and southwest, executing a small cyclonic loop into the Bay of Campeche. Upper-level winds gave way to an anticyclone above the depression, and the system became a Tropical Storm Lorenzo on September 27 about convert|130|nmi|km east of Tuxpan. Rapid intensification brought Lorenzo to hurricane status early that evening, less than twelve hours after becoming a tropical storm. Lorenzo reached its peak intensity on September 28, then weakened slightly before making landfall near Tecolutla, Mexico as a minimal hurricane. The small circulation weakened rapidly after landfall, and the system dissipated the next day.

Six deaths in Mexico were attributable to Lorenzo; mostly attributable to flash floods and mudslides. The states of Puebla and Veracruz reported damage from rain and high winds. Two hundred people were forced to evacuate in Hidalgo when the San Lorenzo River overflowed its banks. Lorenzo made landfall in virtually the same location that Hurricane Dean had struck a month earlier.

1-min winds=35
Melissa began as a tropical wave that exited the western coast of Africa on September 26. The next day an area of low pressure developed near the Cape Verde islands, and the system soon organized into Tropical Depression Fourteen on September 28.cite web|url=|title=Tropical Depression Fourteen Discussion 1|accessdate=2007-09-29|author=Avila|date=2007-09-28|publisher=National Hurricane Center] The depression drifted westward between very weak steering currents. Ordinarily a system would be steered along the edge of a subtropical ridge, but a low pressure system over the northeastern Atlantic subdued its development.cite web|url=|title=Tropical Cyclone Report for Tropical Storm Melissa|accessdate=2007-10-23|author=Richard D. Knabb|date=2007-10-13|publisher=National Hurricane Center]

While inching westward, the depression strengthened slightly and became Tropical Storm Melissa on September 29, tying the record for most tropical storms to form in a month.cite web|url=|title=Tropical Weather Summary - September 2007|accessdate=2007-11-12|author=Mainelli et al|date=2007-10-01|publisher=National Hurricane Center] The next day increasing westerly shear weakened Melissa back to a tropical depression. As it lost deep convection, the depression moved rapidly toward the west-northwest along the southern edge of a regenerating low-level ridge. Thunderstorm activity sputtered, and the depression degenerated to a remnant low on the 30th about convert|475|nmi|km west of the Cape Verde Islands. The low tracked along the low-level ridge for the several days, and merged with a frontal zone northeast of the Leeward Islands on October 5. Since Melissa did not affect land, there were no reports of damage or casualties associated with the storm.

Tropical Depression Fifteen formed from a large and complex area of disturbed weather that extended from the Caribbean Sea into the western Atlantic. On October 8 the eastern end of the system formed a surface low and gradually developed convection as it moved northeastward. It is possible that the system's formation was helped by the remains of Hurricane Karen.cite web|url=|title=Tropical Cyclone Report for Tropical Depression Fifteen|accessdate=2007-11-26|author=Jack Bevin|date=2007-11-22|publisher=National Hurricane Center] While convert|645|nmi|km|abbr=on southeast of Bermuda the system was sufficiently organized to declare it a tropical depression on October 11. The depression maintained its intensity while an upper-level trough moved through the area. In its wake the cyclone was left with hostile conditions, including strong northerly wind shear.cite web|url=|title=Tropical Depression Fifteen Discussion 1|accessdate=2007-11-26|author=Bevin|date=2007-10-12|publisher=National Hurricane Center] The depression weakened to a remnant low on October 12 and merged with a frontal zone two days later. The resulting extratropical low strengthened slightly until it was absorbed by a larger extratropical system north of the Azores on October 17. Because the system remained far from land, no damages were reported.

Hurricane Noel

Dissipated=November 2
1-min winds=70
During the evening of October 27, a low pressure system that had been slowly developing over the eastern Caribbean gained enough organization to be declared Tropical Depression Sixteen. It steadily intensified and became a tropical storm on the afternoon of October 28. It made landfall in Haiti on October 29, and then meandered across the western Caribbean near Cuba for the next three days. Noel brought torrential rain to the region, killing at least 168 people. It then accelerated northeastward, passing through the Bahamas before strengthening to a hurricane on November 1. Noel began an extratropical transition on November 2. While sustained winds were still at Category 1 strength, the NHC issued its final advisory that afternoon. The Canadian Hurricane Centre issued ongoing advisories every three hours on Post-tropical Storm Noel as it approached Canada's eastern provinces until it completed its transition to being fully extratropical on November 4 while over Labrador, shortly before it crossed back into the Atlantic, heading towards West Greenland.

Dissipated=December 13
1-min winds=50
In the second week of December, after the official end of the hurricane season, a low developed east of the northernmost Lesser Antilles. It slowly acquired subtropical characteristics, and late on December 10, the NHC declared it Subtropical Storm Olga while just north of Puerto Rico. It is the first post-season storm since Tropical Storm Zeta in the 2005 season, making this season one of the few with activity both before and after the official bounds of the hurricane season. The storm made landfall on December 11 on the eastern tip of the Dominican Republic. Later that evening, Olga transitioned into a tropical storm just after making landfall. Further weakening took place and the storm degenerated into a remnant low late on December 12.

Flooding and mudslides caused at least 40 deaths - one in Puerto Rico, two in Haiti and at least 37 in the Dominican Republic. []
