on the morning of September 10. The disturbed weather, nested off the coast of Bermuda, was one of the remnants of an old frontal trough that had extended from Hispaniola to the central north Atlantic Ocean. This particular area of disturbed weather become part of the northeast portion of a low-pressure system. On September 10, a reconnaissance aircraft found sustained winds of and a 1010 millibar (29.83 inHg) pressure reading, indicating development into a tropical depression. The depression moved to within of Bermuda and slowly intensified. Late that afternoon, Tropical Depression Five had intensified into a storm and was named Chantal. Chantal intensified rapidly, intensifying to hurricane status late on September 11. It then turned to the east and gained a weak upper-level cirrus-cloud outflow. The structure of the system changed little over the next 24 hours, before Chantal lost organization and was downgraded to a tropical storm on the night of the 12th. Overnight, all convection in Chantal dissipated, and its forward speed decreased as it headed north. A frontal system attracted and absorbed the remnants of Chantal by the night of September 14. Effects on Bermuda were minimal, with the island getting winds only up to and a few thundershowers. However, Chantal generated swells of offshore. Tropical Depression Six Tropical Depression Six formed on September 18 from a tropical wave. The depression caused heavy rainfall in the Lesser Antilles, before degenerating into an open tropical wave on September 20 near the Dominican Republic. Tropical Storm Dean Tropical Storm Dean originated from inside a frontal cloud band, which had moved off the Eastern Coast of the United States on September 22. During the next few days, the band became stationary from the Bahamas to beyond Bermuda. During this period, a 1035 millibar (30.56 inHg) high pressure cell had become settled over the northeastern United States. This resulted in a strong pressure gradient and winds near gale force along the eastern coast. A low-level circulation formed from the frontal cloud band on September 26 about east of central Florida. Dean was first identified on the afternoon of September 26 as a subtropical storm. An Air Force reconnaissance flight was sent to Dean on September 27 and only reported winds of at from the center. A pressure of indicated that Dean was strengthening as it headed northward. Additionally, satellite pictures showed that the subtropical cyclone was emerging from the cloud. This
