Subtropical Storm One was a short-lived subtropical cyclone that brought copious amounts of rainfall to central Florida in late June 1974. The storm originated in an area of convection that detached from a tropical depression over the southwestern Gulf of Mexico on June 24. A new area of low pressure developed underneath the convection and the system began to intensify. Later that day, the storm had become sufficiently organized to be classified as a subtropical depression. Early on June 25, it made landfall near Clearwater, Florida with winds of 50 mph (85 km/h) and later attained its peak intensity over eastern Florida with winds of 65 mph (100 km/h). After reemerging into the Atlantic Ocean, the system began to weaken as it underwent an extratropical transition. The storm ultimately dissipated off the coast of North Carolina early on June 26. Despite its relatively weak strength, the system produced nearly of rain around Tampa, Florida, and the National Hurricane Center reported upwards of nearby. Around Lake Okeechobee, precipitation totals of were common. The heavy rainfall led to moderate flooding across the state. One tornado was confirmed to have touched down in association with the cyclone. Three people drowned as a result of the storm and damage amounted to $10 million (1974 USD, $ in 2009 USD). Meteorological history A tropical depression was situated over the southwestern Gulf of Mexico on June 22, 1974. By June 24, the depression began to weaken as it moved near the Mexican coastline, causing convective activity to move away from the center of circulation. Later that day, a new area of low pressure developed underneath the convection in the central Gulf of Mexico. It continued to mature, and around 1800 UTC, the system had become sufficiently organized to be classified as a subtropical depression. Although subtropical, the storm was operationally considered to be non-tropical, but was reassessed in a post-season analysis of the system. Upon becoming subtropical, the storm tracked rapidly towards the northeast at . Early on June 25, the depression intensified into a subtropical storm as it neared the Florida coastline. Reconnaissance missions were flown into the storm until it made landfall near Clearwater, Florida with winds of 50 mph (85 km/h) during the morning of June 25. Although over land, the system continued to intensify as it moved through the Florida Peninsula. Roughly six-hours after landfall, the storm attained its peak intensity with
