After strengthening to a 60 mph (97 km/h) tropical storm as it moved to the west-northwest, wind shear weakened Erin and caused it to degenerate into a remnant low on September 5.

At its closest approach, Erin passed 105 miles (169 km) east-northeast of Bermuda near peak intensity, and subsequently weakened as it turned to the east.

Large swells from the hurricane produced rough surf and rip currents along the East Coast of the United States.

[2] Following an increase in convection and conformation of a low-level circulation by a buoy, it is estimated the system developed into Tropical Depression Six late on September 1, while located 1,600 miles (2,600 km) east of the Lesser Antilles.

With weak to moderate upper-level wind shear over the system, the depression gradually organized and intensified into Tropical Storm Erin on September 2.

[6] The storm slowly strengthened, and attained an initial peak intensity of 60 mph (97 km/h) while located about 1,150 miles (1,850 km) east of the Lesser Antilles.

[9] A surface circulation redeveloped in the northern portion of the remnants of Erin, and the system developed into a tropical depression again late on September 6, while located 365 miles (587 km) north-northwest of where it previously dissipated.

[11] Erin quickly strengthened later that day to reach a peak intensity of 120 mph (190 km/h) and a minimum central pressure of 968 mbar (28.6 inHg).

[2] Shortly after reaching its peak intensity, Erin passed 105 miles (169 km) east-northeast of Bermuda, its closest approach to the island.

Multiple short-wave troughs weakened the western portion of the subtropical ridge, and on September 11, Erin decelerated as it turned to the east.

It gradually accelerated its forward motion, and on September 15, after weakening to a strong tropical storm, Erin passed just east of Cape Race, Newfoundland.

[2] Convection gradually diminished as it moved through the north Atlantic Ocean,[12] and later on September 15, Erin transitioned into an extratropical storm.

[16] Large waves broke a boat from its moorings, though two men swam through the rough seas to prevent the yacht from running aground.
