Observations from Air Force Reserve reconnaissance aircraft found Bertha had weakened to a tropical storm at 5 a.m. Tuesday.
A National Hurricane Center advisory reported Bertha's center was positioned about 475 miles west of Bermuda, roughly 200 miles off the North Carolina coast. The storm was traveling north-northeast at roughly 22 mph, with maximum sustained winds of 65 mph; winds of tropical storm strength — at least 39 mph — were measured 125 miles from the center, primarily to the east of the center.
It was expected to pass about midway between the Atlantic coast and Bermuda late Tuesday morning. A turn toward the northeast and an increase in forward speed was expected to begin late Tuesday and continue into Wednesday. A gradual weakening was forecast for the next two days.
The storm was not expected to create any hazards on land. No other tropical weather was expected to develop during the next five days.
