The 1983 Atlantic hurricane season was the least active Atlantic hurricane season ever recorded. The season officially started on June 1, 1983, and ended on November 30. The seaon had only a total of 4 named storms, which was less than half of the average number of storms in a season. In addition, it was the least active season since ACE recording began in 1950.

StormsEdit

Tropical Depression OneEdit

Tropical depression (SSHS)
  
DurationJuly 29, 1983 – July 30, 1983
Peak intensity55 km/h (35 mph) (1-min) 

This was a small depression that affected the Lesser Antilles, but did not cause much damage.

Tropical Depression TwoEdit

Tropical depression (SSHS)
  
DurationJuly 31, 1983 – August 3, 1983
Peak intensity55 km/h (35 mph) (1-min) 

Hurricane AliciaEdit

Category 3 tropical cyclone (SSHS)
DurationAugust 15, 1983 – August 21, 1983
Peak intensity185 km/h (115 mph) (1-min)  962 hPa (mbar)

Alicia formed in the north-central part of the Gulf of Mexico on August 15. It traveled west, strengthening into a hurricane. It quickly reached Category 3 strength as it approached the Texas coastline, and made landfall at Galveston, Texas on August 18 at its strongest intensity. The storm then moved northward, its eye passing over Houston. Alicia still kept its tropical characteristics while over land, but eventually becoming extratropical and combining itself with another storm over northern Kansas on September 21. A total of 21 people died in the storm, which caused $5.1 billion (2005 USD) of damages.

Hurricane BarryEdit

Category 1 tropical cyclone (SSHS)
DurationAugust 24, 1983 – August 29, 1983
Peak intensity130 km/h (80 mph) (1-min)  986 hPa (mbar)

An African tropical wave crossed the Atlantic Ocean and strengthened into Tropical Storm Barry for a short time just off the east coast of Florida on August 24. Barry weakened to a depression just before it made landfall near Melbourne, Florida, but managed to cross the Florida peninsula and continued west across the Gulf of Mexico. In the central Gulf, it began to restrengthen, and was a minimal Category 1 hurricane when it made landfall in northeastern Mexico. Barry then began to quickly weaken over land at about 1200 UTC August 29 and soon dissipated.

Hurricane ChantalEdit

Category 1 tropical cyclone (SSHS)
DurationSeptember 10, 1983 – September 14, 1983
Peak intensity120 km/h (75 mph) (1-min)  992 hPa (mbar)

A group of scattered tropical thunderstorms 200 km south of Bermuda, strengthened into the fifth tropical depression of the 1983 season. An Air Force Reconnaissance aircraft found winds of 35 kt (40 mph, 65 km/h) and was named Tropical Storm Chantal. Chantal continued to strengthen and developed into a minimal hurricane with 75 mph (120 km/h) winds on September 11 and maintained that strength until September 13, when it weakened back into a tropical storm.

Chantal travelled northeast over open waters, missing the island of Bermuda, before weakening and being destroyed by a frontal system on September 15. As Chantal never made landfall, no damage or fatalities were reported that was related to the storm.[1] However, Chantal created giant waves that were 30–40 ft (9–12 m) high across the East Coast of the United States.[2]

Tropical Depression SixEdit

Tropical depression (SSHS)
  
DurationSeptember 19, 1983 – September 21, 1983
Peak intensity55 km/h (35 mph) (1-min) 

This was a depression that formed over the Lesser Antilles. It caused no major damage.

Tropical Storm DeanEdit

Tropical Storm (SSHS)
DurationSeptember 26, 1983 – September 30, 1983
Peak intensity100 km/h (65 mph) (1-min)  999 hPa (mbar)

Tropical Storm Dean was a short-lived storm that began as a subtropical storm which developed between Bermuda and the Bahamas on September 26. The subtropical storm headed north-northeast and became tropical the next day.[3] Gale warnings were issued from North Carolina to New England that were produced by Dean, but the storm turned northwest and made landfall on the eastern shore of Virginia on September 30. The storm died out several hours later.[3] Dean was one of only two tropical storms ever to make landfall in eastern shore of Virginia, the other storm being Tropical Storm Bret from the 1981 season.[4]

Overall damage turned out to be light with only minor beach erosion and flooding along parts of the Virginian coastline.[3][4]

Accumulated Cyclone Energy (ACE) RatingEdit

ACE (104kt2) – Storm:[5]
1 6.38 Alicia 2 4.27 Chantal
3 3.14 Barry 4 3.07 Dean
Total = 16.86 (17)

The table on the right shows the ACE for each storm in the season. ACE means the 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 higher ACEs. ACE is only calculated for full advisories on tropical systems at or exceeding 35 knots (39 mph, 63 km/h) or tropical storm strength. The 1983 season had a cumulative ACE of 16.86 (17), which is extremely below normal and currently the least active season on record since 1914, which had an ACE rating of 2.53.
