Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Mon Aug 11 2025
For the North Atlantic...Caribbean Sea and the Gulf of America:
1. 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.
2. 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.
3. 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 changes for further
tropical development.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...10 percent.
