1925 Florida tropical storm
The 1925 Florida tropical storm was the deadliest tropical cyclone to impact the United States that did not become a hurricane. The fourth and final storm of the season, it formed as a tropical depression on November 27 near the Yucatán Peninsula, the system initially tracked southeastward before turning north as it gradually intensified. After skirting western Cuba on November 30, the storm reached peak winds of before striking central Florida on December 1. Within hours, the system transitioned into an extratropical cyclone and emerged into the Atlantic Ocean. The system moved onshore once more on December 2 in North Carolina before turning east, away from the United States. On December 5, the system is presumed to have dissipated offshore.〔
Throughout the system's existence, it was responsible for 73 fatalities, most of which resulted from offshore incidents. The worst loss of life took place off East Coast, where the 30 crewmen of the ''American SS Catopazi'' drowned. Property damage amounted to $3 million, $1 million of which was in Jacksonville.
==Meteorological history==
The 1925 Florida tropical storm was first identified on November 27, 1925 as a tropical depression situated to the southeast of the Yucatán Peninsula, nearly a month after the official end of the hurricane season. Situated over waters, the system slowly intensified, attaining tropical storm status roughly 12 hours after forming, as it drifted towards the southeast before abruptly turning north-northwestward. Throughout November 30, the storm quickly strengthened as it brushed the western tip of Cuba with winds of 50 mph (85 km/h).〔 Once in the Gulf of Mexico, the storm turned northeastward and intensified to peak winds of .〔 The lowest known barometric pressure attained by the storm was 995 mbar (hPa; 29.38 inHg) as it moved inland.〔 Within hours of reaching this strength, the storm made landfall just south of Fort Myers, Florida early on December 1 as it began to transition into an extratropical cyclone.〔 The storm was originally thought to have moved ashore as a minimal hurricane, thus becoming the latest-landfalling hurricane in United States history. However, a reanalysis in 2011 lowered the peak winds.〔 While crossing the Florida peninsula, the storm briefly weakened as it completed its transition; however, once back over water, it re-intensified.〔
Off the coast of The Carolinas, the former tropical storm became a large and powerful extratropical cyclone, attaining peak winds of 90 mph (140 km/h) along with a pressure of 979 mbar (hPa; 28.91 inHg), measured by the ''USS Patoka''.〔〔 Gale force winds extended to at least New Jersey, where winds of 70 mph (110 km/h) were recorded.〔 Throughout December 2, the storm gradually slowed as it tracked roughly parallel to the East Coast. Later that day, the system moved onshore again, this time between Wilmington and Cape Hatteras,〔 with winds equivalent to a minimal hurricane.〔 A strong area of high pressure located over the Canadian Maritimes caused the system to turn towards the east-southeast.〔 Over the following few days, the storm gradually weakened as it moved away from North Carolina. By December 5, the storm was no longer identifiable and is presumed to have dissipated offshore. However, a monthly weather review published in 1925 that documented the system indicated that the cyclone continued towards the east, eventually impacting Bermuda and the Azores.〔 Later analysis in 2009 concluded that a separate extratropical low, which formed near the remnants of the storm, was responsible for inclement weather in both areas.〔
