Overview
- The National Hurricane Center upgraded Invest 99L to Tropical Depression Six on Saturday, Sept. 19, placing its center about 525 miles southwest of the Azores with maximum sustained winds near 35 mph and a very slow northward drift.
- NHC guidance calls for a general northeast motion for the next 24 to 36 hours with slight strengthening possible during that time and gradual weakening expected thereafter.
- If winds reach 39 mph the system would be named Fay and some forecasts project that could happen briefly on Sunday, though significant intensification is not expected.
- No coastal watches or warnings are in effect and the depression poses no immediate threat to land, but mariners and nearby island interests should continue to monitor updates as the track and intensity window can change quickly.
- The development underscores a broader contrast this season as a strong El Niño has suppressed Atlantic storms while multiple eastern Pacific invests, including EP98 and EP99, hold high odds of becoming tropical depressions and could affect offshore Mexican waters.
