An area of unsettled weather developed between the Bahamas and Bermuda on September 6, and over the next few days convection increased in intensity and coverage. On September 8, the system gained sufficient organization to be declared a subtropical depression off the Southeast United States coast; later that day, the system was named Subtropical Storm Gustav. After attaining tropical characteristics on September 10, Gustav passed slightly to the east of the Outer Banks of North Carolina as a tropical storm before moving northeastward and making two landfalls in Atlantic Canada as a Category 1 hurricane on September 12.[32][33]
