Subtropical Storm One was a short-lived subtropical storm, the only one of the inactive 1982 Atlantic hurricane season. It tracked from the Gulf of Mexico up to New England without gaining full tropical characteristics. The storm was the only system of 1982 to affect the east coast of the United States, and it caused three fatalities and caused $10 million in damage (1982 USD).

[edit] Storm history
The subtropical storm had a unusual formation by forming from an interaction of three different systems near the Yucatán. This occurrence is unusual but not unique as Subtropical Storm One of the 1974 Atlantic hurricane season did so as well.[1] A reconnissance flight on June 17 reported that there appeared to be multiple transient circulations at the surface, but no well-defined center.[2] The multiple circulations merged creating a strong trough over the eastern Gulf of Mexico. The first disturbance can be traced back two days before in the northwest Caribbean Sea. The disturbance moved north and then a low-pressure center formed over the Yucatán Peninsula. Conditions in the Gulf of Mexico were favorable for tropical storm formation, however westerly wind shear forced the system to not strengthen. Some severe weather had been occurring over the Florida Peninsula as early as June 16, as the fringes of disturbance moved across the Florida Straits and over the Peninsula.
A subtropical depression formed on June 18 in the Gulf of Mexico. The subtropical depression gained subtropical storm status over Florida. The storm was not named because the policy at the time was not to name subtropical cyclones. After crossing the Outer Banks of North Carolina, the storm moved east and remained far out to sea, so the subtropical storm did not significantly affect the east coast of Virginia. Even though the pressures remained low, the storm expanded and became distorted. The subtropical storm entered the Canadian Hurricane Center's area of responsibility on June 20 and was declared extratropical near Atlantic Canada the same day.[3]
[edit] Preparations
Several warnings were issued in association with the subtropical storm. On June 16, severe thunderstorm watches and warnings were issued for Florida. The next day, more warnings were issued, including a tornado, severe thunderstorm warnings, small craft advisories, special marine warnings, and various types of special weather statements for heavy rains. Five gale warnings were issued on June 18 and June 19 for the cities on the western coast of Florida. All warnings were discontinued by 12 p.m. EDT (1600 UTC) June 19. The same day, a gale warning was issued from Cape Henlopen, Delaware to Watch Hill, Rhode Island.[2]
The subtropical storm postponed the bi-annual Newport, Rhode Island to Bermuda sailboat race for two consecutive days due to the the forecast one of the storm. Subsequent reports from sailboats said that with the track of the storm, if not for the delay, there would have been a marine disaster.[2]
[edit] Impact
[edit] Florida
The subtropical storm made landfall in Florida on the morning of June 18, causing gales, heavy rains, flooding, beach erosion and possible tornadoes. The highest winds were recorded at 36 knots and up to 42 knots during a thunderstorm at Macdill Air Force Base in Tampa at 4:17 am EDT (0817 UTC) on June 18. Rainfall peaked at 10.72 inches in Desoto City. Other storm rainfall amounts range from 4 to 6 inches and 6 to 8 inches at some places. Rainfall also reached the Florida Panhandle and southern Florida, totaling at about one to five inches of rain.[4][5]
Twelve tornadoes were reported to have been spawned by the subtropical storm. The first was in Hendry County. A tornado formed on June 17 at 2015 CDT (0115 UTC June 18) reaching a magnitude of F2 on the Fujita Scale. One person was killed and another one was injured with $250,000 in damage. Two tornadoes including the one in Hendry County were at least F2 strength.[6]
High tides and waves caused flooding and beach erosion from Naples to the Tampa Bay area. Some waterfront buildings suffered damage from undermining including widespread damage of marinas and some boats. Several bulkheads and rock revetments experienced minor damage in Naples and Marco Island. Several man‑made dune structures seaward of the Coastal Construction Control Line in Collier County received minor damage at Vanderbilt Beach and Marco Island. A total of twenty-five homes in Florida were destroyed. Damage was estimated to be $100,000. [7]
Three people were killed in Florida in association with the subtropical storm with thirteen injuries. A Brevard County woman died when a canoe overturned and an Orange County child was killed when he was swept into a drainage ditch. [2] One-hundred thirty families were evacuated a few days after the storm from the Arcadia River area because the Peace River crested above flood stage. Damage in Florida totaled out to $10 million.
[edit] The Carolinas
The storm's effects north of Florida were minor. Rainfall reached up to nine inches in extreme eastern South Carolina and four inches in eastern North Carolina. Winds reached 50 mph with gusts up to 66 mph at the Oak Island Coast Guard Station near Cape Fear, North Carolina and 54 mph with gusts of 77 mph at the offshore tower at Frying Pan Shoals about fourty miles southeast of Cape Fear on June 18 with 70 mph winds the next day. A sixty-eight foot fishing trawler sunk off the coast of Cape Fear in North Carolina from the high waves, no one was killed as the sailors were rescued by the Coast Guard on June 19. Flooding was reported with tides of two to three feet in the Carolinas. Otherwise damage was minimal.[2]
[edit] Georgia and Virginia
Rainfall from the subtropical storm reached both states, reaching maximum peaks of up to five inches on the Georgia coast and seven inches on the Georgia/South Carolina border. Rainfall totaled to about one inch on the Virginian coast. However, no damage was reported. [5]
[edit] Atlantic Ocean
A ship encountered winds of a minimum tropical storm with gusts as high as a maximum tropical storm. The ship also encounted a tidal surge of 15 to 20 feet.[4][2]
