peaked as a Category 3 hurricane at 06:00 UTC on September 1, with reconnaissance measuring sustained winds of 115 mph (185 km/h) and a minimum barometric pressure of . Frances almost immediately began weakening thereafter, falling to Category 2 intensity by midday on September 1. The weakness in the Azores High continued to influence the storm's path, causing Frances to recurve to the east around that time. A slower weakening trend commenced, with the storm being downgraded to a Category 1 on September 3. After curving northeastward, Frances began losing tropical characteristics while approaching the Azores. The transition to an extratropical cyclone was fully completed at 12:00 UTC on September 4, with Frances centered about south-southwest of Flores Island in the Azores. The extratropical remnants passed through the Azores and completed a counterclockwise loop north of the islands before dissipating on September 7. Subtropical Storm Three On September 12, the interaction between mid-tropospheric low and a diffuse stationary front led to the formation of a low pressure system over central Florida. As it moved north-northeastward, a circulation formed, resulting in the development of a subtropical depression over Polk County, Florida, on September 13. The next day, it intensified into a subtropical storm and peaked with maximum sustained winds of 45 mph (75 km/h) while just off the coast of Georgia. The storm quickly made landfall near Charleston, South Carolina, at the same intensity. After moving inland, the cyclone weakened to a subtropical depression late on September 15 near the North Carolina–South Carolina state line. The storm dissipated over southern Virginia on September 17. Tides produced by the storm ranged from above normal along the coast of the Carolinas, leaving minor beach erosion. The storm produced wind gusts up to in Charleston, South Carolina. Rain fell in several states along the East Coast of the United States and was generally beneficial. However, in central and southern Maryland, where the storm dropped a peak total of of precipitation in Towson, downpours resulted in flooding. The Baltimore area received its highest amount of rainfall for any day in the month of September. Heavy precipitation delayed commutes, while water entered some homes, flooded roads, and resulted in a few school closures. Hurricane Gloria On September 18, a tropical wave entered the Atlantic from the west coast of Africa. While the wave moved west-northwestward at about , an upper-tropospheric cold low pressure interacted with and
