A stationary upper-level disturbance, strong onshore flow, and a weak frontal boundary produced persistent heavy rainfall and squalls across a large portion of east central Florida on October 7-8.
A strong gale then formed over the Bahamas on October 9 and moved northwest and onto the Brevard and Volusia County coast late in the evening. As the gale approached the coast, heavy convective bands and storm-force winds developed west of the center of circulation. While not a tropical storm, the system briefly possessed some tropical/sub-tropical characteristics. Winds gusted between 50 and 80 mph along much of the coast. Additional heavy rains added to the totals of the previous several days. The combination of the saturated grounds and high wind gusts caused numerous, mostly small trees, to be toppled, mainly across coastal Brevard and Volusia Counties. Tree branches were also downed and many power outages occurred.
A large portion of east central Florida received 72-hour storm total rainfall greater than 5 inches, with parts of Brevard, Indian River, and Osceola Counties reaching 10 to nearly 17 inches of rain. Unseasonably dry soil conditions prior to the event minimized significant flooding, however, minor flooding, and high levels of standing water were experienced within several counties.
