. 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

. 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.

. On June 1, the first day of the officially defined hurricane season, this cyclone organized into Tropical Storm Barry despite being located in an area of high shear, and warnings were immediately issued along the western Florida coastline. Barry provided much-needed precipitation to parts of Florida and Georgia, which were experiencing drought conditions. Barry made landfall near Tampa Bay, Florida on June 2 as a minimal tropical storm. Soon thereafter Barry was downgraded to a tropical depression as it began its extratropical transition. Barry became an extratropical cyclone late in the afternoon of June 2. On June 3, the cyclone moved up the coast of the Carolinas

Tropical Storm Ingrid

A large tropical wave exited Africa on September 6 and initially failed to develop due to strong easterly shear. On September 9, a broad low pressure area developed about midway between Africa and the Lesser Antilles. The wind shear slowly weakened, and early on September 12 Tropical Depression Eight developed about 1125 miles (1815 km) east of the Lesser Antilles. The system moved west-northwestward due to a ridge to its north, and with continued wind shear, it remained a tropical depression for 24 hours before convection increased further. Early on September 13 it intensified into Tropical Storm Ingrid, reaching peak winds of 45 mph (75 km/h). Operationally, it was not upgraded to a tropical storm until that evening.

Ingrid remained a tropical storm until September 15, when it weakened to a tropical depression due to high shear from a strong tropical upper tropospheric trough
Tropical Upper Tropospheric Trough
A tropical upper tropospheric trough , also known as the mid-oceanic trough, is a trough situated in upper-level tropics.

. Ingrid briefly reorganized on September 16, before weakening further and degenerating into an open wave early on September 17. The remnants turned northwestward within the low-level steering flow, and dissipated on September 18 without redevelopment. There were no reports of damage or casualties associated with Ingrid because the storm never threatened land.

 on September 21. As it moved westward, deep convection gradually increased over the disturbance as its broad low-level circulation became better-defined. By September 24, as the system traveled northwestward it organized enough to become a tropical depression. Six hours later the depression was upgraded to Tropical Storm Karen.

Karen's organization and intensity remained steady for the next day. Early on September 26, however, the storm strengthened significantly. In post-operational analysis the cyclone was determined to have reached hurricane-strength for about twelve hours. The strengthening was short-lived because a sharp upper-level trough to the west of Karen increased the amount of vertical wind shear
