The 1950 Atlantic hurricane season was the first year in the Atlantic hurricane database (HURDAT) that storms were given names in the Atlantic basin. Names were taken from the Joint Army/Navy Phonetic Alphabet, with the first named storm being designated "Able", the second "Baker", and so on. It was a very active season with sixteen tropical storms, with eleven of them developing into hurricanes. Six of these hurricanes were intense enough to be classified as major hurricanes—a denomination reserved for storms that attained sustained winds equivalent to a Category 3 or greater on the present-day Saffir–Simpson scale. One storm, the twelfth of the season, was unnamed and was originally excluded from the yearly summary, and three additional storms were discovered in re-analysis. The large quantity of strong storms during the year yielded, prior to modern reanalysis, what was the highest seasonal accumulated cyclone energy (ACE) of the 20th century in the Atlantic basin; 1950 held the seasonal ACE record until broken by the 1995 Atlantic hurricane season. However, later examination by researchers determined that several storms in the 1950 season were weaker than thought, leading to a lower ACE than assessed originally. This season also set the record for the most tropical storms, eight, in the month of October.
The tropical cyclones of the season produced a total of 88 fatalities and $38.5 million in property damage (1950 USD). The first officially named Atlantic hurricane was Hurricane Able, which formed on August 12, brushed the North Carolina coastline, and later moved across Atlantic Canada. The strongest hurricane of the season, Hurricane Dog, reached the equivalent of a Category 4 hurricane on the Saffir–Simpson scale and caused extensive damage to the Leeward Islands. Two major hurricanes affected Florida: Easy produced the highest 24-hour rainfall total recorded in the United States, while King struck downtown Miami as a Category 4 hurricane and caused $27.75 million (1950 USD) of damage. The two major landfalls made the 1945–1950 period the only five-year period to feature five major hurricane landfalls in the United States—a record that held until tied in 2000–2005. The last storm of the year, an unnamed tropical storm, dissipated on November 12.
Seasonal summary
The season officially began on June 15 and ended on November 15; these dates conventionally delimit the period of each year when most tropical cyclones form in the Atlantic basin. This season was the first time that the United States Weather Bureau operated with radar technology to observe hurricanes away from land. Although the season began on June 15, tropical activity typically does not begin before August. The tropics remained tranquil through early August, and the U.S. Weather Bureau noted that the season had been "remarkably quiet". The inactive period ended on August 12, when the first tropical storm developed east of the Lesser Antilles. This storm received the name "Able" as part of the Joint Army/Navy Phonetic Alphabet. (The same alphabet was also used in the 1951 and 1952 seasons, before being replaced by female naming in 1953.)
Before the end of August, four hurricanes had formed in the Atlantic, two of which attained major hurricane status. A major hurricane is a tropical cyclone with winds of at least ; a storm of this intensity would be classified as a Category 3 or greater on the Saffir-Simpson Hurricane Scale introduced in the 1970s. In contrast to the busy August, only three named storms developed in September—although three of the August hurricanes lasted into September. Hurricane Dog became the strongest hurricane of the season on September 6 with winds of ; its peak strength occurred over the open Atlantic Ocean, so it did not cause significant damage when it was at its strongest. It was among the most severe hurricanes on record in Antigua, where the hurricane struck early in its duration. Eight tropical storms or hurricanes formed in October, which is greater than in any other year.
In total, there were sixteen tropical storms during the season, of which five (Tropical Storm How, Tropical Storm Mike and three unnamed tropical storms) did not attain hurricane status. Overall, six major hurricanes occurred during the year. The Hurricane Hunters made about 300 flights into hurricanes during the season, the most since the practice began in 1943. The number of storms was above average; in a typical year, eleven tropical storms, six hurricanes, and between two and three major hurricanes take place. With the numerous major hurricanes, the season produced a high accumulated cyclone energy (ACE) of 211, although it was originally assessed as 243 before reanalysis. At one point, the 1950 total was the highest on record, before being surpassed by the 2005 season. This value is an approximation of the combined kinetic energy used by all tropical cyclones throughout the season.
Systems Hurricane Able
The beginning of the season was considered "remarkably quiet" by the U.S. Weather Bureau, with no noteworthy activity until early August. A Hurricane Hunters flight into an easterly wave on August 12 indicated a developing tropical storm east of the Lesser Antilles; it was later given the name "Able", which is the first name in the Joint Army/Navy Phonetic Alphabet. It moved steadily northwestward and reached hurricane status on August 14, as it passed to the north of the Leeward Islands. The next day, Hurricane Able turned to the west and west-southwest, due to a high pressure system to its north. On August 17 it attained major hurricane status, and by early on August 18 reconnaissance aircraft measured winds of 140 mph (225 km/h), though Atlantic hurricane reanalysis later determined that those winds were unrepresentative of the intensity. At the time, the storm was 350 miles (565 km) in diameter. On August 19, Able turned to the north, and attained its peak intensity of while doing so; shortly before peak intensity, aircraft measured a central pressure of , the lowest in the life of the storm. The next day Able accelerated to the northeast, after passing just offshore Cape Hatteras, North Carolina. Having maintained peak winds for 12 hours, Hurricane Able began to weaken on August 20, and early the next day it moved quickly by Cape Cod. It produced winds of hurricane force in Nova Scotia before it moved ashore on August 21 near Goodwood with winds of . Subsequently, it deteriorated into an extratropical cyclone, and Able crossed Newfoundland before dissipating early on August 24 in the far northern Atlantic Ocean.
Along the coast of North Carolina, the hurricane produced light winds and rough waves, as well as moderate precipitation. Heavier rainfall occurred in southern New England, peaking at 6.89 inches (175 mm) in Beechwood, Massachusetts. Flooding was reported in portions of New York City. The resulting slick roads from the rains caused nine traffic fatalities across New England. The storm produced 55 mph (90 km/h) gusts in Nantucket and Cape Cod, along with high tides and waves. Offshore, the waves damaged a freighter headed for Florida. In Nova Scotia, Able produced hurricane-force winds, the only land along its path to receive such winds; a gust of 99 mph (160 km/h) was reported in Halifax. The hurricane also dropped heavy rainfall, including over 4.92 inches (125 mm) in Annapolis Valley. Initially there were three fishing boats missing throughout the region, although two later returned to harbor. By August 22, the third was still missing over the Grand Banks, which prompted a rescue team to search for the boat. Many other boats crashed against the coast, and two children died when their raft capsized. Two bridges and several roadways were washed out or flooded, and in Charlottetown, Prince Edward Island, floodwaters left roadways impassable. In Canada, the hurricane left more than CA$1 million, half of which in Annapolis Valley, and split between crops, communications, and fishing industries.
Hurricane Baker
A tropical wave exited western Africa on August 13, which developed into Tropical Storm Baker east of the Lesser Antilles on August 18. It moved northwestward and later turned to the west, attaining hurricane status on August 21. The next day, the hurricane attained Category 2 intensity just as it crossed over Antigua, where heavy damage was reported. More than 100 homes were damaged or destroyed, which left thousands homeless. Afterward, the hurricane began to weaken, and later on August 22 its winds decreased to tropical storm status. The cyclone then struck Montserrat as a strong tropical storm. The next day it struck southwestern Puerto Rico, and shortly thereafter weakened into a tropical depression, passing over the Dominican Republic. Baker turned more to the west, re-attaining tropical storm status before striking eastern Cuba on August 24. In Cuba, 37 people died, and the property losses reached several million dollars.
On August 25, Baker weakened to tropical depression status while crossing Cuba, but soon thereafter regained tropical storm intensity in the western Caribbean Sea. Two days later, Baker entered the Gulf of Mexico, and by the next day Baker had regained hurricane status. It turned northward, reaching a peak intensity of on August 30. Baker weakened slightly before making landfall near Gulf Shores, Alabama with winds of on August 31. Property and crop damage totaled $2.55 million (1950 USD), primarily between Mobile, Alabama and Saint Marks, Florida. Torrential rainfall fell throughout the region, with the largest total occurring in Caryville, Florida, where of precipitation were recorded. The heavy precipitation was responsible for extensive crop damage across the region. The hurricane also spawned two tornadoes, one of which destroyed four houses and a building in Apalachicola, Florida. In Birmingham, Alabama, high wind downed power lines, which caused one death and two injuries due to live wires. While inland, Baker tracked northwestward and eventually dissipated over southeastern Missouri on September 1.
Hurricane Charlie
Hurricane Charlie developed on August 21 to the southwest of the Cape Verde islands. At the time, the Weather Bureau did not consider Charlie to be a tropical cyclone until almost a week later. For four days, the storm tracked generally to the west as a weak tropical storm. On August 25, it turned to the northwest and intensified, becoming a hurricane on August 28. On August 30, Charlie attained peak winds of , although the Hurricane Hunters estimated higher winds. At the time, the hurricane was stalled to the east-southeast of Bermuda, and subsequently turned to a westward drift. On September 2, Charlie turned to the north and northeast. At the time, it co-existed with two other hurricanes, Dog and Easy; it is a rare occurrence for three hurricanes to exist simultaneously in the Atlantic. Charlie slowly weakened and lost tropical characteristics, and by September 5 Charlie had transitioned into an extratropical cyclone about southeast of Halifax, Nova Scotia. It dissipated later on September 5 without having affected land.
Hurricane Dog
Hurricane Dog is believed to have developed from a tropical wave that left the coast of Africa on August 24. Its first observation as a tropical cyclone occurred on August 30, when it was a hurricane; the storm is believed to have begun farther east as a Cape Verde-type hurricane, but was not detectable before August 30. At the time, Dog was located east of the Lesser Antilles, and it quickly attained major hurricane status as it moved to the west-northwest. Dog passed through the Lesser Antilles with winds of . It was considered among the worst hurricanes in the history of Antigua, where thousands were left homeless. Damage was estimated at $1 million (1950 USD, USD), and there were two deaths from drowning in the region.
