Bertha, the Atlantic's second named storm of the season, became the second to reach hurricane status as well Monday morning.
The storm had maximum sustained winds of 80 mph as of 11 a.m., according to the National Hurricane Center. It was about 230 miles northeast of the Bahamas, and is forecast to pass about midway between the U.S. Atlantic coast and Bermuda, not directly affecting either.
The hurricane center forecasts little change in Bertha's strength Monday and most of Tuesday, before the storm is expected to weaken.
Forecasters noted that despite its hurricane status, the storm is relatively "unimpressive" as far as tropical cyclones go.
