The National Hurricane Center is tracking a tropical wave that emerged from the west coast of Africa, though the system poses no immediate threat to the U.S. Virgin Islands or Puerto Rico. The disturbance, noted in the NHC’s 2:00 a.m. outlook on Friday, is producing disorganized showers and thunderstorms in the far eastern Atlantic.
Forecasters say the wave will move west to west-northwest at 10–15 mph across the Atlantic. Environmental conditions could support some development, but any strengthening is expected to be slow. The NHC gives the system near-zero chances of formation within 48 hours and only a 40 percent chance over the next seven days.
