Allison's remnants reentered reached the Gulf of Mexico and emerged over open waters. The low once again became nearly stationary about south of Galveston, Texas, and despite more favorable upper-level winds, it showed no signs of redevelopment. Due to dry air and moderate westerly wind shear, the storm transformed into a subtropical cyclone. While the subtropical depression moved eastward, a new low level circulation redeveloped to the east, and Allison quickly made landfall on Morgan City, Louisiana on June 11. At around the same time, the surface center reformed to the east-northeast of its previous location, aligning with the mid-level circulation. Strong thunderstorms redeveloped over the circulation, and Allison strengthened into a subtropical storm over southeastern Louisiana. The storm intensified further to attain sustained winds of and a minimum barometric pressure of about near Mclain, Mississippi, accompanied by a well-defined eye-like feature. The storm was officially downgraded to a subtropical depression at 0000 UTC on June 12. Somewhat accelerating, the depression tracked to the east-northeast through Mississippi, Alabama, Georgia, and South Carolina before becoming nearly stationary near Wilmington, North Carolina. The depression drifted through North Carolina and sped to the northeast for a time in response to an approaching cold front. Though satellite and radar imagery show the system was well-organized, the system slowed and moved erratically for a period of time, executing what appeared to be a small counterclockwise loop. The storm began tracking in a generally northeasterly direction, and crossed into the southern Delmarva Peninsula on June 16. The subtropical remnants reached the Atlantic on June 17, and while located east of Atlantic City, New Jersey, winds began to restrengthen, and heavy rains formed to the north of the circulation. The low was interacting with a frontal boundary, and started merging with it, as it accelerated to the northeast at . The remnants of Allison briefly reintensified to a subtropical storm through baroclinic processes, though it became extratropical while south of Long Island. By later on June 17, the low was situated off the coast of Rhode Island, spreading a swath of precipitation over New England. The remnants of the tropical storm were then absorbed by the frontal boundary by June 18, and eventually passed south of Cape Race, Newfoundland on June 20, where the extratropical cyclone dissipated. Preparations Shortly after the storm formed, officials in Galveston County, Texas issued a voluntary evacuation for the western end of
