1950 Atlantic hurricane season
The 1950 Atlantic hurricane season was the first year in which tropical cyclones were given official 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 an active season...

Meteorological history

Tropical Storm Dog was first observed as a 70 mph (112.7 km/h) tropical storm on August 30, when the SS Sibrodin reported gale force winds and an area of low pressure

. At the time, reconnaissance practices were in their infancy, so it is possible the hurricane was over-estimated. Although the wind speed measurements may not be accurate, Dog was a formidable hurricane while over the western Atlantic, producing wave heights of over 100 feet (30.5 m).

Hurricane Dog maintained its peak intensity for about 18 hours. On September 7, the cyclone attained a central pressure of 948 mbar (27.99 inHg), which was the lowest pressure in association with the hurricane. A building ridge

 of high pressure to its north caused it to decelerate and weaken steadily for unknown reasons as it turned to the west; by September 9, the intensity had decreased to 90 mph (145 km/h). On September 10, as it turned northward, Hurricane Dog briefly re-intensified slightly to winds of about 100 mph (160.9 km/h) before weakening again.
