Tropical Storm Henriette was strengthening in the central Pacific Ocean far northeast of Hawaii and could become a hurricane but posed no threat to land, the National Hurricane Center said Sunday.
The storm was located about 415 miles (670 kilometers) north-northeast of Hilo, Hawaii, according to the Miami-based center, and was moving northwest at 16 mph (26 kph). That course was expected to continue for the next few days, taking Henriette well north of the Hawaiian islands.
