Tropical Weather Outlook...Corrected
NWS National Hurricane Center Miami FL
800 AM EDT Mon Aug 11 2025

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

Corrected to fix a typo and include mention of gale warnings for
non-tropical area of low pressure south-southeast of Nova Scotia.

Eastern Tropical Atlantic (AL97):
Shower and thunderstorm activity has persisted and continues to
show signs of organization with a well-defined area of low pressure
located just to the west of the Cabo Verde Islands. If these
structural trends continue, the system is likely to become a
tropical depression or storm, possibly as soon as later this
morning. Locally heavy rainfall and gusty winds are expected to
continue today across portions of the Cabo Verde Islands, and
interests there should monitor the progress of this system.
Regardless of development over the next couple of days, the system
is expected to continue moving westward to west-northwestward at 15
to 20 mph across the eastern and central tropical Atlantic.

* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...90 percent.

Central Atlantic (AL96):
A weak trough of low pressure located over the central Atlantic is
only producing limited shower and thunderstorm activity.
Significant development of this system is becoming unlikely over
the next few days as the system drifts generally northward,
remaining over the central Atlantic.

* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

Northwestern Atlantic:
A non-tropical area of low pressure is currently located a few
hundred miles to the south-southeast of Nova Scotia, Canada. While
current shower and thunderstorm activity with the system is limited,
this system is drifting over the warm waters of the Gulf Stream
where some tropical or subtropical development could occur over the
next day or two. By the middle of this week, the system is expected
to move northward over cooler waters, ending its chances for further
tropical development. For more information on this system, including
gale warnings, see High Seas Forecast issued by the National Weather
Service.

* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.

800 AM EDT Sat Aug 23 2025

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

Southwestern Atlantic (AL90):
Satellite images indicate that an area of low pressure has formed
about 500 miles south-southeast of Bermuda, and the associated
showers and thunderstorms continue to show signs of organization. A
tropical depression is expected to form later today or tonight, with
further intensification to a tropical storm likely on Sunday while
the low moves northward over the southwestern Atlantic. An Air
Force Reconnaissance aircraft is scheduled to investigate the low
this afternoon. Interests in Bermuda should monitor the progress of
this system as watches could be still 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...near 100 percent.
* Formation chance through 7 days...high...near 100 percent.

East of the Windward Islands (AL99):
Disorganized showers and thunderstorms continue in association with
a tropical wave located about 850 miles east of the Windward
Islands. Some development of this system could occur during the
next few days while the system moves quickly westward at about 20
mph. Locally heavy rainfall and gusty winds are possible across
portions of the Windward Islands as the system moves through on
Sunday and Monday. By the middle of next week, conditions over the
central 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.
