1982 Florida subtropical storm
Subtropical Storm One was the only sub-tropical cyclone of less active Atlantic hurricane season in 1982. The storm went from two different systems has resulted in the Caribbean Sea and the Gulf of Mexico. The two systems are merged into a trough, while began to form a circulation off the coast of Florida on June 18. The low pressure system moved across Florida and strengthened over land to a storm. This came over the Atlantic Ocean and moved to the northeast. On June 20, the system became extratropical near Newfoundland. The storm was the only system that the east coast of the United States met. It caused damage to property in the amount of 10 million U.S. dollars (1982) and three people died from the effects of the storm.
Storm History
The subtropical storm arose in an unusual way by the mutual influence of two different system in the vicinity of the Yucatán Peninsula. However, such a cyclone genesis is not an isolated case, in 1974, an unnamed subtropical storm formed in a similar way. A reconnaissance flight was on 17 June that there were several emerging circulations at the surface, but no well-defined storm center. The first fault can be traced back to 15 June in the northwestern Caribbean. She emigrated to the north, together with a low pressure area that formed over the Yucatan. A trough merged with the low pressure area, which created an even stronger trough over the eastern Gulf of Mexico. The conditions in the Gulf of Mexico were favorable for the development of a tropical system. Some storms occurred on June 16 over Florida, as the foothills of the fault through the Straits of Florida and across the peninsula attracted.
On June 18, began to form a circulation in the eastern Gulf and storm warnings were issued. The system arrived on the morning of June 18, just north of Spring Hill about the country and was declared during the day to the Subtropical Storm One. At the time, subtropical storms by the National Hurricane Center were not named, but were given an ordinal number. The subtropical storm came back over water, moved to the northeast and crossed on June 19, the Outer Banks of North Carolina. Although the minimum central pressures remained low, the circulation stretched and distorted. The subtropical storm reached its peak on June 18, with wind speeds of 110 km / h reached its lowest air pressure but only on June 20 with 984 mbar ( hPa). On the same day the subtropical storm near the Canadian Maritime provinces was declared extratropical system.
Preparations
In connection with the subtropical storm several storm warnings were issued. On June 16 Severe weather warnings were issued for Florida and the next day were added warnings before tornadoes and Seewetterwarnungen, especially for small watercraft. Due to heavy rains local warnings of flash floods were made known. Storm warnings were issued on June 18 and 19 for the west coast of Florida, which ended on 19 June at 16:00 UTC clock. On the same day there was a storm warning from Cape Henlopen, Delaware, and Watch Hill, Rhode Iceland.
Because of the subtropical storm the two -yearly yacht race from Newport, Rhode Iceland has been moved to Bermuda on two consecutive days because of the predicted storm. A disaster was prevented in the high seas by this measure.
Effects
In the area of his main band over Cuba, the storm unloaded 728 mm of rain.
Had the greatest impact of the storm on reaching Florida on the morning of June 18, where it caused high winds, heavy rain, flash flooding, beach erosion, and tornadoes. The highest winds on land were at 66 km / h and 77 km / h during a storm on the Macdill Air Force Base in Tampa measured, the highest rainfall totaled in Arcadia with 272 mm, while the majority of the State of 25-125 mm of precipitation experienced. Storm surge and high waves led to Überwemmungen and beach erosion between Naples and the area around the Tampa Bay area. Some of the buildings on the shore were damaged by washout, marinas and boats were damaged by wind and waves. Less damage, addressed the storm on bulkheads and breakwaters in Naples and Marco Iceland and to the artificial coastal defenses at Vanderbilt Beach in Collier County. In Floria came by the effects of the storm, three people were killed, thirteen more were injured. In Brevard County, a woman died when their canoe capsized and a child was killed when it was swept into a drainage ditch in Orange County. Some 130 families were evacuated as a few days after the storm the Peace River exceeded the high water mark. The third victim was a man from the Hendry County, who was killed in his trailer when it was destroyed by a tornado. The subtropical storm dissipated across Florida from twelve tornadoes, at least two of which reached a magnitude of F2 on the Fujita scale. One of them was formed in Hendry County on June 18 at 1:15 UTC clock. A total of 25 houses were destroyed in Florida. The damage to property in the state, added up to around 10 million U.S. dollars (1982).
The effects of the storm were north of Florida low. The rainfall amounts ranged up to 230 mm in the extreme east of South Carolina and up to 100 mm in North Carolina. The wind speed was up to 60 km / h with gusts up to 100 km / hr at the Coast Guard Station Oak Iceland at Cape Fear, North Carolina and 87 km / h with gusts of 123 km / h southeast of Cape Fear on the 65 km off-shore lighthouse Frying Pan Shoals on June 18 and continuing winds of 110 km the next day. A 19 -meter fishing boat sank off the coast near Cape Fear, where the crew was rescued on 19 June by the United States Coast Guard. The storm surge reached two to three feet above normal in the Carolina states. In Georgia, the rainfall totaled up to 130 mm on the coast, being on the border of South Carolina 175 mm were measured. On the coast in Virginia, the rainfall was more than 25 mm. A ship reported wind gusts that were just below hurricane strength and nbspm a swell from 4.5 to 6 &.
