systems at or exceeding 39 mph (63 km/h), which is the threshold for tropical storm strength. Systems Subtropical Storm One On April 21, a low-pressure area separated from the prevailing westerlies about southeast of Bermuda, and developed into a subtropical depression at 1200 UTC. The system maintained a large comma-shaped cloud pattern around the low-level circulation. Operationally, it was not classified until 27 hours later. Isolated from strong steering currents, the depression tracked northwestward at , and intensified into a subtropical storm early on April 22. It gradually became better organized, with a large convective band in the eastern semicircle. Reports from a nearby ship indicated peak winds of , with swells of . The National Hurricane Center remarked the potential for the system transitioning into a tropical cyclone. An approaching trough caused the storm to stall and weaken the deep convection. On April 23, the cyclone weakened to depression status due to strong wind shear. A hurricane hunter's flight into the system confirmed the weakening, and also reported a 1.8 °F (1 °C) temperature rise in the center, suggesting a warm core and some tropical characteristics. Early on April 24, the subtropical depression turned eastward, maintaining limited convection. At the time, forecasters anticipated the depression would continue east-northeastward and become an extratropical cyclone. By late on April 24, the system was too weak to classify using the Dvorak technique, and the NHC ceased issuing advisories. Within 24 hours, the circulation dissipated as the system continued eastward through the westerlies. Tropical Depression One A tropical wave emerged off the western coast of Africa on June 12, and eventually developed into Tropical Depression One in the southeastern Gulf of Mexico. Operationally, the National Hurricane Center designated this system as Tropical Depression Two, which led to confusion because of Subtropical Storm One in April, and then another Tropical Depression Two in July. Outflow from Hurricane Celia in the Pacific Ocean and a trough in the Gulf of Mexico generated wind shear on the depression, which prevented it from intensifying into a tropical storm. The depression curved north-northeastward and eventually made landfall in near Tampa, Florida, on June 26 around 1500 UTC. As it was moving ashore, the National Hurricane Center noted that the depression was too poorly organized to locate the center of circulation, and discontinued advisories on the system. The depression dropped heavy rainfall in Cuba, peaking at . Large amounts
