Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Sat Aug 9 2025

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


2. Eastern Tropical Atlantic:
A tropical wave that has now emerged offshore the west coast of
Africa is producing a large area of disorganized showers and
thunderstorms. Environmental conditions appear favorable for gradual
development of this system, and a tropical depression could form by
the middle to latter portion of next week while it moves
west-northwestward at 15 to 20 mph across the eastern and central
tropical Atlantic. Locally heavy rainfall is possible Sunday and
Monday across portions of the Cabo Verde Islands.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...medium...40 percent.

Eastern Tropical Atlantic (AL97):
A broad area of low pressure, associated with a tropical wave, is
producing a large area of disorganized showers and thunderstorms
just off the west coast of Africa.  Environmental conditions appear
conducive for gradual development of this system, and a tropical
depression could form by the middle to latter portion of next week
while moving west-northwestward at 15 to 20 mph across the eastern
and central tropical Atlantic.  Locally heavy rainfall is possible
Sunday and Monday across portions of the Cabo Verde Islands.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...medium...50 percent.

Eastern Tropical Atlantic (AL97):
Showers and thunderstorms have increased in association with a
tropical wave located just to the southeast of the Cabo Verde
Islands.  Environmental conditions appear conducive for further
development of this system, and a tropical depression is likely to
form by the middle to latter portion of this week while moving
west-northwestward at 15 to 20 mph across the eastern and central
tropical Atlantic.  Regardless of development, locally heavy
rainfall and gusty winds are possible today and Monday across the
Cabo Verde Islands.
* Formation chance through 48 hours...low...30 percent.
* Formation chance through 7 days...high...80 percent.

Eastern Tropical Atlantic (AL97):
Updated:  Recently received satellite-derived wind data indicate
that a well-defined low pressure system has formed about midway
between the west coast of Africa and the Cabo Verde Islands with
maximum winds of about 35 mph.  Although the associated shower and
thunderstorm activity still lacks some organization, only a small
increase in the organization could lead to the formation of a
tropical depression before the low moves near or across the Cabo
Verde Islands tonight and on Monday.  Regardless of development,
locally heavy rainfall and gusty winds are possible today and Monday
across the Cabo Verde Islands, and interests there should monitor
the progress of this system.

Even if a tropical depression does not form over the next day or so,
environmental conditions appear conducive for later development,
and a tropical depression is likely to form by the middle to latter
portion of this week while moving west-northwestward at 15 to 20 mph
across the eastern and central tropical Atlantic.  
* Formation chance through 48 hours...medium...40 percent.
* Formation chance through 7 days...high...80 percent.
