(Reuters) - Bertha has become the second hurricane of the 2014 Atlantic season, the U.S. National Hurricane Center (NHC) said on Monday.

The hurricane was located about 230 miles (370 km) east-northeast of Great Abaco Island in the northern Bahamas with maximum sustained winds of 80 miles per hour (130 km/h), the NHC said.

"On the forecast track, Bertha will continue to move away from the Bahamas today and pass about midway between the U.S. east coast and Bermuda on Tuesday," the Miami-based weather forecasters said.
