Hurricane Able (1950)
Hurricane Able was the first named tropical cyclone in the Atlantic hurricane database, and was also the first of six major hurricanes in the 1950 Atlantic hurricane season. Its development was confirmed on August 12 by the Hurricane Hunters, which is a group that intentionally flies into a hurricane for observations. Hurricane Able initially threatened to strike the Bahamas, but instead turned to the northwest and later to the northeast. As it neared the Outer Banks, Able reached peak winds of , equivalent to a modern-day Category 3 hurricane on the Saffir-Simpson hurricane wind scale. After brushing those islands and Cape Cod, Able moved ashore on Nova Scotia as a minimal hurricane. It later crossed Newfoundland and dissipated on August 24.
The hurricane prompted standard precautions in the Bahamas and Florida, although it did not affect the region. In North Carolina, winds and waves brushed the coast, while around New York City, heavy rainfall caused some flooding. Along Cape Cod and Nantucket, Able produced winds up to 55 mph (90 km/h) and high waves, and across New England there were nine traffic fatalities. The hurricane killed 2 people in Canada and caused over $1 million in damage.
==Meteorological history==
The beginning of the 1950 Atlantic hurricane 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.〔〔
Able was expected to continue to the west toward the Bahamas and Florida. It was the strongest hurricane to threaten the Bahamanian capital, Nassau, since a hurricane in 1929. The hurricane turned to the northwest, however, sparing the Bahamas from the strongest winds. 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.〔〔
