Around mid-September, there was an area of disturbed weather just northeast of the Bahamas associated with an upper-level trough. Gradually the vorticity worked down to surface level as the system moved generally north-northwestward over the following days. Shear was fairly high in the area, but the low managed to develop enough convection to be named Tropical Storm Odette off the U.S. mid-Atlantic coast on September 17.
Though it formed pretty close to land, it was already moving out to the northeast. Moreover, it was already beginning extratropical transition! The thunderstorm activity was well east of the center of circulation, and this "center" was in fact multiple low-level swirls orbiting one another. The poorly-organized cyclone degraded further as shear increased, but nevertheless strengthened due to interaction with an approaching front. Just a day after being named, Odette became post-tropical. The low moved out over the open north Atlantic and stalled southeast of Atlantic Canada for a few days. Though it was monitored for redevelopment, ex-Odette did not regenerate into a tropical cyclone. Within a few more days, it was swept away by the next trough entering the Atlantic.
The above image shows Odette shortly after formation. At least three vortices are visible, with the deep convection displaced east of the center.
Odette was only tropical for a day (see circular dots), but the post-tropical low spent several days meandering the north Atlantic after becoming post-tropical (triangular points).
