Prior to becoming a tropical cyclone, the system dropped locally heavy rainfall in portions of southern Florida. Palm Beach International Airport recorded on August 8, a record for the date. The system spawned a weak tornado near Boca Raton, which downed a few trees and damaged shingles from one house. In Sarasota, high tides from the system affected 200 sea turtle nests, of which 20 had to be transported to a safer location. Once in the Gulf of Mexico, the developing system threatened the area affected by the Deepwater Horizon oil spill; this prompted BP to stop operations temporarily in constructing a relief well. The same event occurred a week later when the depression was threatening to redevelop.
