The remnant low-pressure area continued to the west-northwest, and on September 6, the system gradually produced deep convection. 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 (585 km) north-northwest of where it previously dissipated. The depression moved to the north-northeast, then turned to the north-northwest, and regained tropical storm status on September 7. Erin steadily intensified, and its convection and cloud pattern became much better organized on September 8. On September 9, Erin intensified into a hurricane while located 104 miles (167 km) east-northeast of Bermuda, and a 40-mile (65 km) wide eye developed. Erin quickly strengthened later that day to reach a peak intensity of 120 mph (195 km/h) and a minimum central pressure of ; however, some sources claim that Erin may have been a little stronger.
