The 2005 Atlantic hurricane season officially began June 1, 2005, and will last through November 30, 2005. These dates conventionally delimit the period when most tropical cyclones are expected to form in the Atlantic Ocean.

The season began very quickly, with tropical storms and major hurricanes forming unusually early, setting numerous records for number and strength of storms. Hurricane Dennis caused major damage in Haiti and struck Cuba at full-force before striking the Florida Panhandle. Hurricane Emily was an even stronger storm that hit the Yucatan Peninsula and northeastern Mexico.

In late August, Hurricane Katrina caused damage to south Florida before moving into the Gulf of Mexico. In the Gulf of Mexico it moved slowly in conditions favorable for intensification. It rapidly intensified into a category 5 hurricane with a minimum pressure of 902 mb and maximum sustained windspeeds of 175 mph, making it the fourth most intense hurricane on record in the Atlantic Basin. It weakened to a category 4 hurricane when it made landfall on August 28, passing just to the east of New Orleans and moving northeastward into Mississippi. It caused major flooding and wind damage along the central Gulf Coast and is expected to be the costliest hurricane in U.S. history and the deadliest US hurricane in at least 77 years.

In addition to these hurricanes, two additional tropical storms (Arlene and Cindy) have made landfall in the United States and three (Bret, Gert, and Jose) have made landfall in Mexico.

Two tropical storms formed in June, five formed in July, five formed in August and one so far in September.

Seasonal forecasts

Forecasts of hurricane activity are issued before each hurricane season by noted hurricane expert Dr. William Gray and his associates at Colorado State University, and separately by NOAA forecasters.

Dr. Gray's team defines the average number of storms per season (1950–2000) as 9.6 tropical storms, 5.9 hurricanes, and 2.3 hurricanes reaching or exceeding Category 3 strength. A normal season, as defined by NOAA, has 6 to 14 named storms, with 4 to 8 of those reaching hurricane strength, and 1 to 3 reaching or exceeding Category 3 strength on the Saffir-Simpson scale.

Preseason forecasts

On December 3, 2004, Dr. Gray's team issued its first extended-range forecast for the 2005 season, predicting a slightly above-average season (11 named storms, 6 hurricanes, 3 of Category 3 or higher). Additionally, the team predicted a greatly increased chance of a major hurricane striking the East Coast of the United States and the Florida peninsula. Though the forecast predicts above-normal activity, the level predicted is less than in the 2004 season. [1]

In its April 1, 2005 update, Dr. Gray's team revised the December forecast upward. The updated forecast predicted 13 named storms, 7 hurricanes, and three of Category 3 or greater strength. The chance of a storm striking the U.S. was also raised slightly. [2]

On May 16, 2005, NOAA issued its outlook for the 2005 season, forecasting a 70% chance of above-normal activity, with 12–15 named storms, 7–9 hurricanes, and 3–5 hurricanes reaching Category 3 intensity. The Accumulated Cyclone Energy (ACE) value for the season is expected to be 120–190 percent of the median. [3]

On May 31, Dr. Gray's team revised its April forecast upwards. The updated forecast predicted 15 named storms, 8 hurricanes, and 4 hurricanes greater than Category 3 on the Saffir-Simpson scale. [4]

Mid-season outlook

On August 2, 2005, NOAA released an updated outlook on the remainder of the season. The outlook calls for from 18 to a record-tying 21 tropical storms, 9 to 11 hurricanes, and 5 to 7 becoming major hurricanes. The ACE value is now forecast to be 180 to 270 percent of the median. These figures are roughly twice those of a normal season. While June and July were unusually active, August and September are expected to contain the peak of seasonal activity as in most seasons. NOAA notes a higher than normal confidence in the forecast of above-normal activity. [5]

On August 5, 2005, Dr. Gray and his associates followed suit, and issued their updated forecast. It is consistent with the NHC's update, calling for 20 tropical storms, 10 hurricanes, and 6 major hurricanes. [6]

Storms

Tropical Storm Arlene

Tropical Storm Arlene on June 10, 2005, at 20:15 UTC.

Early in the season—nearly two months earlier than the first storm formation in 2004—a low-pressure area formed and persisted north of Honduras. Despite significant shear, the low managed to organize, and was designated Tropical Depression One on June 8. It was upgraded to Tropical Storm Arlene the next day.

Arlene began heading north towards Cuba that day, but it was a very large and poorly organized storm under the influence of heavy shear. It produced precipitation over a very wide area; the Cayman Islands reported tropical storm-force winds and heavy rain over 150 miles (240 km) east of the center.

As it crossed the western tip of Cuba on the morning of June 10, the storm began gaining strength. Most of the precipitation and wind of the storm were located north and east of the center, so most of the effects of the storm were on land long before it made landfall. The shear weakened as Arlene entered the Gulf of Mexico, and the storm strengthened to just under Category 1 strength.

Arlene made landfall just west of Pensacola, Florida around 2 p.m. CDT (1900 UTC) on June 11, though most of its effects were onshore long before the center. Arlene was the most intense land-falling June storm since Hurricane Allison hit the same location as a strong tropical storm during the 1995 season. Though weakened heavily by landfall, Arlene persisted as a dissipating tropical depression, passing into Indiana on June 12 and Michigan on June 13, when it became extratropical.

The only death attributed to Arlene was a woman caught in riptide in Miami Beach, Florida, far from the center of circulation.[7]

Tropical Storm Bret

Tropical Storm Bret on June 29, 2005, as it closes in on the east coast of Mexico at 1245 UTC.

Late in June, an area of disturbed weather formed in the Bay of Campeche. A Hurricane Hunter flight was dispatched (#), and on arrival found a closed circulation [8]. This observation caused the system to be classified as Tropical Depression Two in the evening of June 28. Two hours later, observations from the same aircraft indicated that it had reached tropical storm strength, and it was named Tropical Storm Bret. This was the first time that two tropical storms had formed in June since the 1986 season, and only the thirteenth time since 1851.

The storm moved west-northwest, making landfall near Tuxpan, Veracruz, Mexico around 7 a.m. CDT (1200 UTC) on June 29 as a weak tropical storm. It continued inland, producing heavy rain over the state of Veracruz, until dissipating over the mountains of San Luis Potosi late on June 29.

Hundreds of homes were damaged, and several towns, including Naranjos and Chinampa, about 60 miles south of Tampico, were severely flooded. The only reported fatalities were the two occupants of a car that was swept away by floodwaters in Naranjos ([9]).

Tropical Storm Cindy

Tropical Storm Cindy just before landfall on July 6, 2005, at 0245 UTC.

Early season activity continued in July, with a vigorous tropical wave strengthening into Tropical Depression Three in the northwestern Caribbean Sea on July 3. While it began organizing quickly, it did not reach tropical storm strength before striking the Yucatán Peninsula early on July 4. Once over land, the organizing trend stopped, and the depression began losing its circulation.

Later on July 4, a new center of circulation began forming to the north of the original center over the Gulf of Mexico. Early the next day it strengthened and was named Tropical Storm Cindy. The storm began heading north across the Gulf towards Louisiana and made landfall near Grand Isle late on July 5, and started losing strength over Mississippi and Alabama. It lost tropical characteristics over the Carolinas on July 7.

Even though it had weakened to a depression and was well inland, Cindy's effects were still felt; some parts of Atlanta Motor Speedway and Tara Field airport in Hampton, Georgia suffered severe damage from an F2 tornado spawned by the storm. Hartsfield International Airport in Atlanta had over 5 inches (130 mm) of rain on July 6, its sixth-highest one-day rainfall ever (since 1878). Most of that fell during just two hours (8 to 10 p.m. EDT). This is more rain than it normally gets in all of July. Many other places, such as Slidell, Louisiana, Gulfport, Mississippi, Mobile, Alabama, and Salisbury, Maryland, also saw over 5 inches.

Three deaths were attributed to Cindy—two in Georgia and another in Alabama.

Hurricane Dennis

Main Article: Hurricane Dennis

Tropical Depression Four formed in the southeastern Caribbean on the evening of July 4, the first storm of the season to form away from Mexico and Central America. On the morning of July 5, it strengthened into Tropical Storm Dennis in the eastern Caribbean. The newly named storm began moving rapidly to the west-northwest.

It reached hurricane strength on the afternoon of July 6 while approaching the southern coast of Hispaniola as a strong and well-organized Category 1 storm. The next day it strengthened rapidly to become a Category 4 major hurricane, the earliest in the season that a storm had achieved this strength since Hurricane Audrey in 1957. The track then turned slightly more to the north, bringing Dennis between Jamaica and Haiti on July 7.

Just south of Cuba, Dennis intensified into the strongest storm on record to form before August in the Atlantic basin. On July 8, Dennis passed over Cuba close to the capital, Havana. After moving over Cuba, it dropped to Category 1 intensity. However, a second episode of rapid intensification occurred on July 9 as it moved north toward the Gulf Coast of the United States, and it again achieved Category 4 intensity. This second phase of strengthening "bordered on insane," according to a discussion advisory issued by the National Hurricane Center. After passing over cooler water along the coast and weakening to Category 3 intensity, Dennis made landfall on Santa Rosa Island on July 10 just southeast of Pensacola, Florida.

Dennis claimed at least 70 lives: 44 in Haiti, 16 in Cuba, and 10 in the U.S. Also, more than 100 people have been reported missing in Haiti. It is considered to be the worst hurricane to strike Cuba since Hurricane Flora in 1963.

Hurricane Emily

Tropical Depression Five became the fifth named storm of the season east of the Lesser Antilles on July 11. It moved west toward the islands as a moderate tropical storm and hit Grenada on July 14 as a category 1 storm. It entered the Caribbean Sea and began intensifying rapidly. It reached category 4 intensity on July 15, but quickly weakened to category 2 intensity. However, later in the day it reintensified to a category 4 storm. Emily broke Hurricane Dennis's eight-day-old record for the most intense storm to form prior to August when it reached 155 mph on July 16, along with a minimum pressure of 929 mb.

After passing south of Jamaica and the Cayman Islands, Emily made landfall on the Yucatán Peninsula near Tulum on the morning of July 18. Emily dropped down to a Category 1 hurricane but quickly restrengthened to a strong Category 3. Emily made its second landfall in rural northeast Mexico near Boca Madre, Tamaulipas, early on the morning of July 20, and dissipated over the Sierra Madre Oriental the next day.

Emily is blamed for at least seven deaths; one in Grenada, four in Jamaica and two in Mexico.


Tropical Storm Franklin

File:Tropical Storm Franklin July 29 2005.jpg
Tropical Storm Franklin taken July 29, 2005, at 1315 UTC, south of Halifax, Nova Scotia.

A tropical wave off the Bahamas organized into Tropical Depression Six on the afternoon of July 21. The depression became the sixth named storm of the season only two hours later, the first time the sixth storm of the season has ever formed this early in the season. The storm headed northward from the Bahamas, then northeast over the Atlantic, becoming disorganized by July 24 under the effects of shear and drier air. It moved erratically, sometimes wobbling in place, inching closer to Bermuda while barely remaining a tropical storm. Bermuda put up a tropical storm watch for a short time, but dropped it when Franklin moved far west of the island. Bermuda did receive some strong wind gusts, however. Tropical Storm Franklin then accelerated north and northeast, roughly paralleling the East Coast of the United States. Eventually, Franklin became extratropical along the coast of Nova Scotia and Newfoundland, and the remnant was absorbed by a mid-latitude cyclone east of Newfoundland. Franklin achieved maximum sustained winds of 60 mph and a minimum central pressure of 1000 mb.


Tropical Storm Gert

Tropical Storm Gert taken July 24, 2005, making landfall in Mexico.

A tropical wave, which had earlier crossed Honduras and the Yucatán peninsula, organized into Tropical Depression Seven on the afternoon of July 23 in the Bay of Campeche. It was upgraded to Tropical Storm Gert early the next day, the earliest formation of a seventh named storm on record. It strengthened little before making landfall on the coast of Mexico south of Tampico late on July 24 with maximum sustained winds of 45 mph and a minimum central pressure of 1005 mb. It moved inland over central Mexico before dissipating on July 25.

Gert struck in around the same area as Hurricane Emily just four days earlier, causing fear of flooding and landslides due to saturated lands. As a precaution some 1,000 people were evacuated from low-lying residences and business near the towns of Naranjos and Tamiahua. Naranjos was also hit by Tropical Storm Bret earlier.


Tropical Storm Harvey

Tropical Storm Harvey taken August 4, 2005, just south west of Bermuda.

After lingering off the east coast of the U.S. for several days, a tropical wave finally strengthened into the eighth depression of the season due southwest of Bermuda on August 2. Due to its proximity and projected path towards Bermuda, a tropical storm warning was issued for the island. It became a tropical storm the next day.

Harvey was not initially a particularly well-organized storm, and had some subtropical characteristics, but it soon became more tropical in nature. It passed just south of Bermuda early on August 4 while at its peak intensity, with maximum sustained winds of 65 mph and a minimum central pressure of 994 mb. Harvey then headed east and later northeast over the open Atlantic. The storm became extratropical on the afternoon of August 8.


Hurricane Irene

Hurricane Irene taken August 15, 2005, with 90 mph winds

Tropical Depression Nine formed from a tropical wave west of Cape Verde on the afternoon of August 4, the second Cape Verde-type hurricane of the season. The system was expected to strengthen rapidly, but the depression encountered dry air and wind shear as it turned to the northwest and it broke down. Despite poor organization and shearing winds, it reached Tropical Storm strength for a while on August 7–8 and received the name Irene. Further shear and dry air disrupted the cyclone formation, and Irene was downgraded to a tropical depression on August 8.

Irene cycled between apparent reintensification and significant weakening, becoming so disorganized in the early morning of August 10 that forecasters were considering declaring that it had dissipated [10]. However, the depression continued to move westward into warmer waters and shear-free environment, and again attained tropical storm status, rapidly strengthening to just under hurricane strength before leveling off again. On August 14 at 2144 UTC, an Air Force Reserve hurricane hunter read winds of 75 mph (120 km/h), making Irene a minimal Category 1 hurricane. Later, it strengthened even further in low shear conditions under an upper level anticyclone. On August 16 its winds briefly strengthened to that of a category 2 hurricane, but shortly thereafter Irene began to reach cooler waters and weaken. It became extratropical 290 miles (470 km) off Cape Race, Newfoundland, on August 18, having never posed a threat to land.


Tropical Depression Ten

Tropical Depression Ten formed 1100 miles (1765 km) east of the Lesser Antilles on August 13. Conditions were not favorable for development, as strong vertical shear literally ripped the system apart, and advisories were discontinued the next day when it showed no organized deep convection. The remnants of Tropical Depression Ten continued drifting northwestward before degenerating into a tropical wave north of the Leeward Islands. This remnant eventually merged with another system in the "complex genesis" of what would become Tropical Depression Twelve and, eventually, Hurricane Katrina.

Tropical Storm Jose

Tropical Depression Eleven formed in the Bay of Campeche on August 22. Later in the day it strengthened into Tropical Storm Jose over the warm waters of the Gulf of Mexico and achieved a maximum strength of 50 mph before it made landfall in the state of Veracruz, Mexico on August 23. The Mexican government issued Tropical Storm Warnings from Veracruz to Punta El Lagarto. It then rapidly weakened and soon dissipated as it moved inland over Mexico. Eight deaths were attributed to Jose's heavy rains in the Mexican state of Oaxaca. Two more were reported missing [11].

Jose was forming an eye just as it made landfall, but its winds remained well under hurricane strength. [12]

Hurricane Katrina

Main article: Hurricane Katrina

The National Hurricane Center issued a statement on August 23 saying that a tropical depression had formed over the southeastern Bahamas.

The numbering of this system was debated, as Tropical Depression Twelve formed partially out of the remnants of T.D. 10. The naming and numbering rules at the NHC require a system to keep the same identity if it dies then regenerates, which would have normally caused this storm to remain numbered Ten. However, the NHC gave this storm a new number because a second disturbance merged with the remains of Tropical Depression Ten on August 20, and there is no way to tell whether the remnants of T.D. Ten should be credited with this storm.

The system was upgraded to Tropical Storm Katrina on the morning of August 24. Katrina became the fourth hurricane of the 2005 season on August 25 and made landfall later that day around 6:30 p.m. between Hallandale Beach and North Miami Beach, Florida, dumping up to 18 inches of rain

Katrina spent only a few hours over southern Florida, and soon regained hurricane strength after emerging into the Gulf of Mexico. Combined with its slow movement and the extremely warm waters of the Gulf of Mexico, Katrina rapidly intensified. It became a major hurricane on August 27 and attained Category 5 status on the morning of August 28 with 175 mph sustained winds and a minimum pressure of 902 mb. This made Katrina the fourth most intense hurricane on record in the Atlantic basin, surpassing Hurricane Camille of the 1969 season, which was the most powerful hurricane ever to hit the United States. Katrina spent all of August 28 at Category 5 status despite some weakening, but by the early morning of August 29 had declined to a very powerful Category 4 storm.

Katrina proved difficult to forecast, as the models earlier showed widely-varying landfall locations and intensities as soon as it re-entered the Gulf of Mexico, though the hurricane path prediction narrowed to the area around New Orleans. A slight deviation in the hurricane's path to the east early on August 29 avoided a direct hit on the city of New Orleans, sparing it the worst damage from the storm.

Katrina made its second landfall as a strong Category 4 hurricane near Buras, Louisiana with 145 mph winds, and a third, final landfall as a Category 3 hurricane near Pearlington, Mississippi with 125 mph winds after crossing Breton Sound. Massive damage occured in southern Alabama and along the Mississippi coast, and numerous tornadoes were reported in Louisiana, Mississippi, Alabama, Georgia, and the Florida Panhandle.

Despite the fact that New Orleans escaped the worst damage from the storm, two levees along Lake Pontchartrain ultimately were breached by storm surge. One of the breaches is estimated longer than a football field (approximately 120 yds., or 110 m). About 80% of the city is currently flooded, some by as much as 25 ft. (7 m) of water, and the damage estimates are believed to easily top Hurricane Andrew as the costliest hurricane in American history.

So far, seven fatalities have been reported in southern Florida. Two of the deaths were from falling trees, one man crashed into a tree, one person died when their boat capsized, one when waves battered their boat, and one man was found floating in the water around Florida City. A family of five out over the southwestern coast of Florida was suspected dead, but found later alive and rescued by the Coast Guard. [13] Katrina has been blamed for an additional 126 deaths in Biloxi, Mississippi, alone, and that toll could still go higher. There are no figures yet from New Orleans, but that number is expected to reach at least the high hundreds, the Mayor of New Orleans and Governor of Louisiana said they expect it to reach thousands.

Tropical Storm Lee

Tropical Depression Thirteen formed from a tropical wave about 960 miles east of the Lesser Antilles on August 28. It then degenerated into a broad area of low pressure on August 29, but regenerated on August 31 and advisories resumed. Later that day, it strengthened into Tropical Storm Lee. Later in the evening it was downgraded to a tropical depression, having encountered an unfavorable upper level environment. The tropical depression dissipated on the evening of September 1.

Hurricane Maria

Tropical Depression Fourteen formed from a tropical wave 1100 miles east of the Leeward Islands on September 1, and strengthened to a tropical storm the next day. On early September 4 Maria strengthened to Hurricane Maria, the fifth hurricane of the season. It is forecast to pass well east of Bermuda, and therefore to avoid all land areas for the time being. The only possible landfall would be in Atlantic Canada and that is still a week or more away if Maria survives that long. A recurve over the open Atlantic is seen as more likely.

Current

As of 5 am AST September 4 (0900 UTC) the center of Hurricane Maria was located about 645 miles (1040 km) east-southeast of Bermuda. The system was moving north-northwest at 14 mph (22 km/h) with maximum sustained winds of 75 mph (120 km/h). Some strengthening is forecast during the next 24 hours.

For official forecasts, see the NHC's latest public advisory on Tropical Storm Maria.

Records

The 2005 season has already broken numerous records for tropical cyclone activity, and is on pace for many more records.

Rapid formation

Tropical Storm Lee broke the trend, becoming at 2100 UTC on August 31 the third earliest formation of a season's 12th tropical storm, behind storm 12 at 0600 UTC on August 31, 1933, and Luis on August 29, 1995.

Early strength

When its sustained winds reached 150 mph on July 8 and a minimum pressure of 930 mb on July 10, Hurricane Dennis became the strongest storm to form prior to August, and the earliest Category 4 storm to form in the Caribbean.

When Hurricane Emily reached Category 4 intensity on July 15, this became the only season to have two hurricanes reach Category 4 intensity before the end of July. Emily also broke Dennis's eight-day-old record for the strongest storm on record before August when its maximum sustained winds reached 155 mph on July 16, along with a minimum central pressure of 929 mb.

Number of storms

2005 also 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 4; this record was held by the 1966, 1995, and 1997 seasons.

This activity was reflected in the Accumulated Cyclone Energy value at the end of July; at 61, it was the highest ever. The previous highest was 49 in 1916; the modern record was 33 in 1966.

Strongest storms

Hurricane Katrina now ranks as the fourth most intense Atlantic hurricane of all time (behind Gilbert at 888 mb, the Labor Day Hurricane of 1935 at 892 mb, and Allen at 899 mb) and the most intense hurricane on record in the Gulf of Mexico when the storm's central pressure dropped to 902 mb on August 28, 2005. Katrina was also the third most intense hurricane on record to make landfall in the United States in terms of pressure (918 mb), behind the Labor Day Hurricane of 1935 and Hurricane Camille in 1969 (although numerous hurricanes, including Andrew in 1992, Betsy in 1965, Beulah in 1967, Charley in 2004, the Galveston Hurricane of 1900, the 1926 Great Miami Hurricane, and the 1928 Okeechobee Hurricane all made landfall with stronger wind speeds but higher atmospheric pressure).

2005 storm names

The following names will be used for tropical storms and hurricanes that form in the North Atlantic in 2005. This is the same list used for the 1999 season, with the exceptions of Franklin and Lee, which replace Floyd and Lenny. The names not retired from this list will be used again in the 2011 Atlantic hurricane season. Storms were named Franklin, Lee and Maria for the first time in 2005. Names not yet assigned are marked in gray. If there are 22 or more named storms, the letters of the Greek Alphabet will be used to name storms after Wilma. Bold names are currently active.

  • Harvey
  • Irene
  • Jose
  • Katrina
  • Lee
  • Maria (active)
  • Nate (unused)
  • Ophelia (unused)
  • Philippe (unused)
  • Rita (unused)
  • Stan (unused)
  • Tammy (unused)
  • Vince (unused)
  • Wilma (unused)

Names to be retired will be announced by the World Meteorological Organization in the spring of 2006. Any statement about retired names made before then is purely speculative.
