The Atlantic hurricane season officially began on June 1, with the first tropical cyclone developing on June 24. Although 23 tropical depressions developed, only nine of them reached tropical storm intensity; this was near normal compared to the 1950–2000 average of 9.6 named storms. Six of these reached hurricane status, slightly above the 1950–2000 average of 5.9. Furthermore, three storms reached major hurricane status; above the 1950–2000 average of 2.3. Collectively, the cyclones of this season caused at least 84 deaths and over $564.7 million in damage. The Atlantic hurricane season officially ended on November 30, though the final cyclone became

began in June, with the development of a tropical depression on June 24, followed by Tropical Storm Amy on June 27. Four systems originated in July, including Hurricane Blanche. After Tropical Depression Six dissipated on July 30, tropical activity went dormant for over three weeks, ending with the development of Hurricane Caroline on August 24. Another cyclone, Hurricane Doris, also formed in August. September was the most active month of the season, featuring eight tropical cyclones, including hurricanes Eloise, Faye, and Gladys. In October, four systems formed, one of which intensified into Tropical Storm Hallie. Two tropical depressions developed in November. The last system, a subtropical storm, formed on December 6 and transitioned into an extratropical cyclone on December 13. The season's activity was reflected with an accumulated cyclone energy (ACE) rating of 76. Broadly speaking, ACE is a measure of the power of a tropical storm multiplied by the length of time it existed. Therefore, a storm with a longer duration will have high values of ACE. It is only calculated for full advisories on specific tropical and subtropical systems reaching or exceeding wind speeds of 39 mph (63 km/h). Accordingly, tropical depressions are not included here. After the storm has dissipated, typically after the end of the season, the

flights, satellites and ships were used to monitor the storm's intensity and tropical status. After satellite imagery indicated that the system became more symmetrical, developed CDO, and detached from the frontal system, the cyclone was reclassified as Tropical Storm Doris on August 29. Doris made meteorological history when, on August 31, it became the first Atlantic hurricane ever to be upgraded to hurricane intensity solely on the basis of satellite pictures, via the

. The cyclone then curved northward and intensified further during the next few days, becoming a Category 2 hurricane early on September 2. Based on the Dvorak technique, it is estimated that Doris peaked with maximum sustained winds of 110 mph (175 km/h) and a minimum barometric pressure of shortly thereafter. By September 3, the hurricane began interacting with a non-tropical low pressure area. On the following day, Doris quickly weakened to a tropical storm and transitioned into an extratropical cyclone about south-southeast of

Hurricane Eloise

A tropical wave developed into a tropical depression on September 13 to the east of the Virgin Islands. The system tracked westward and strengthened into Tropical Storm Eloise while passing to the north of Puerto Rico. Eloise briefly reached hurricane intensity soon thereafter, but weakened back to a tropical storm around landfall over Hispaniola. The cyclone emerged into open waters of the northern Caribbean Sea. After striking the northern Yucatán Peninsula, Eloise turned northward and re-intensified. In the Gulf of Mexico, the cyclone quickly deepened, becoming a Category 3 hurricane on September 23. The hurricane made landfall west of

, before moving inland across Alabama and dissipating on September 24. The storm produced heavy rainfall throughout Puerto Rico and Hispaniola, causing extensive flooding that left severe damage 59 fatalities. Thousands of people in these areas became homeless as flood waters submerged numerous communities. As Eloise progressed westward, it affected Cuba to a lesser extent. In advance of the storm, about 100,000 residents evacuated from the Gulf Coast region. Upon making landfall in Florida, Eloise generated wind gusts of 155 mph (249 km/h), which demolished hundreds of buildings in the area. The storm's severe winds, waves, and storm surge left numerous beaches, piers, and other coastal structures heavily impaired. Wind-related damage extended into inland Alabama and Georgia. Further north, torrential rains along the entire East Coast of the United States created an unprecedented and far-reaching flooding event, especially into the Mid-Atlantic States. In that region, an additional 17 people died as a result of freshwater flooding from the post-tropical storm; infrastructural and geological effects were comparable to those from

on September 18, the wave quickly developed into a tropical depression about west of the Cabo Verde Islands. Moving northwestward, the depression intensified, according to ships and satellite imagery, becoming Tropical Storm Faye on September 19. The cyclone then moved westward and was unable to intensify further due to increasing wind shear, before weakening to a tropical depression on September 23. Shortly thereafter, Faye turned to the north, crossing an upper trough axis over the central Atlantic. Southwesterly flow aloft allowed the system to re-strengthen, with Faye becoming a tropical storm again on September 25. Faye accelerated to the northwest and deepened into a Category 1 hurricane early on September 26, several hours before reaching Category 2 intensity. Around 23:00 UTC on September 26, the cyclone passed about 35 mi (55 km) east of

At 00:00 UTC on September 27, the hurricane reached its maximum sustained wind speed of 105 mph (165 km/h). Later that day, Faye curved northeast under strong westerly flow. Although the system weakened to a Category 1 hurricane late on September 28, the storm reached its minimum barometric pressure of , observed by a reconnaissance aircraft. Faye then curved eastward and lost tropical characteristics, becoming extratropical at 12:00 UTC on September 29, while situated northwest of

Hurricane Gladys

A tropical wave emerged into the Atlantic from the west coast of Africa on September 17. The system developed into a tropical depression while located about southwest of the Cabo Verde Islands on September 22. Initially, the depression remained weak, but after encountering warm sea surface temperatures and low wind shear, it strengthened into Tropical Storm Gladys on September 24. Moving west-northwestward, the storm then entered a more unfavorable environment, mainly increased wind shear. Despite this, Gladys intensified into a Category 1 hurricane on September 28. Shortly thereafter, the storm reentered an area favorable for strengthening. A well-defined eye became visible on satellite imagery by September 30. As the storm tracked to the east of the Bahamas, a curve to the north began, at which time an anticyclone developed atop the cyclone. This subsequently allowed Gladys to rapidly intensify into a Category 4 hurricane, reaching maximum sustained winds of 140 mph (230 km/h) and a minimum barometric pressure of on October 2. Thereafter, Gladys began to weaken and passed very close to
