フロリダ海峡
The remnant tropical wave gradually curved northwestward and brushed western Jamaica on August 14. As the wave approached the south coast of central Cuba, it rapidly re-organized into a tropical cyclone, becoming a tropical depression again at 18:00 UTC on August 15. Around 00:00 UTC the following day, the depression re-intensified into a tropical storm and made landfall in Cuba near Playa Girón in Matanzas Province. Dennis moved northward across the island and emerged into the Straits of Florida near Cárdenas shortly after 06:00 UTC. While crossing the Straits of Florida, deep convection associated with the cyclone attempted to become concentrated near the center and develop an eyewall. However, interaction with a trough prevented Dennis from intensifying despite passing over warm sea surface temperatures. The storm decelerated while approaching Florida due to weak steering currents.
