Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Sat Aug 23 2025

For the North Atlantic...Caribbean Sea and the Gulf of America:

Southwestern Atlantic (AL90):
Showers and thunderstorms have become a little better organized in
association with a trough of low pressure located a few hundred
miles north of the northern Leeward Islands. Environmental
conditions appear conducive for further development of this system,
and a tropical storm is expected to form this weekend while it moves
north-northwestward and then northward over the southwestern
Atlantic. Interests in Bermuda should monitor the progress of this
system as watches or warnings could be required later today. For
additional information, including gale warnings, please see High
Seas Forecasts issued by the National Weather Service.
* Formation chance through 48 hours...high...80 percent.
* Formation chance through 7 days...high...90 percent.

Central Tropical Atlantic (AL99):
Showers and thunderstorms associated with a tropical wave located
more than one thousand miles east of the Windward Islands have
become less organized over the past 24 hours, and the system is
currently being affected by strong wind shear. No development is
expected through tonight while the system traverses the area of
strong wind shear. The wave could reach a slightly more favorable
environment Sunday and Monday as it approaches the Windward Islands,
and some slow development is possible during that time. By the
middle of next week, conditions over the Caribbean are expected to
be unfavorable for further development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...20 percent.
