 The first storm of the season , Subtropical Storm Andrea , originated from a large extratropical cyclone that formed off the mid @-@ Atlantic coast on May 6 . It deepened steadily along a cold front that pushed through Florida . When the system lost most of its baroclinic support , development ceased until its low moved into warmer waters near the Bahamas . However , interaction between the low and a strong high @-@ pressure system to the north generated hurricane @-@ force winds in the system . Decreasing vertical wind shear allowed the storm to generate deeper convection much closer to the center . By May 9 the previously extratropical cyclone had transformed into Subtropical Storm Andrea while located about 140 miles ( 225 km ) southeast of Savannah , Georgia . Andrea began its subtropical phase as it was weakening , and continued this deterioration as it moved southward into an environment with higher wind shear . By May 11 , Andrea had lost all significant convection and degenerated into a remnant low . Though it produced intermittent bursts of convection , Andrea 's chance of regeneration was extinguished when an advancing cold front pushed it northward and eventually absorbed the system .
