800 AM EDT Sun Jul 13 2025
For the North Atlantic...Caribbean Sea and the Gulf of America:
Northeastern Gulf:
A trough of low pressure is likely to form near the southeastern
U.S. coast during the next day or two and then move westward across
Florida into the northeastern Gulf by Tuesday. Environmental
conditions could support some gradual development of this system
during the middle to late part of this week while it moves westward
over the northeastern and north-central portions of the Gulf.
Regardless of development, heavy rainfall could produce localized
flash flooding over portions of Florida and the north-central Gulf
coast through the mid to late portion of this week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 7 days...low...20 percent.

For the North Atlantic...Caribbean Sea and the Gulf of America:
East of the Florida Peninsula into the Northeastern Gulf (AL93):
Satellite and radar data indicate that the shower and thunderstorm
activity associated with the low pressure located just offshore of
the east coast of Florida remains disorganized. This system is
forecast to move westward across the Florida Peninsula today and
then reach the northeastern Gulf by Wednesday. Environmental
conditions appear generally favorable for additional development,
and a tropical depression could form while the system moves across
the northeastern and north-central Gulf.
Regardless of development, heavy rainfall could produce localized
flash flooding over portions of Florida through mid-week. Heavy
rainfall could also cause flash flooding for portions of the
north-central Gulf Coast during the middle to latter portions of
this week.

For the North Atlantic...Caribbean Sea and the Gulf of America:
Northeastern and north-central Gulf (AL93):
Surface and radar observations indicate that a broad area of low
pressure is moving westward across the Florida Panhandle between
Tallahassee and Panama City. The associated shower and thunderstorm
activity is disorganized and located mainly south and southwest of
the center. This system is forecast to continue moving westward, and
could emerge or redevelop over the far northeastern to north-central
portion of the Gulf later today or tonight, reaching the coast of
Louisiana by Thursday. If this system moves far enough offshore,
environmental conditions over the Gulf appear generally favorable
for additional development, and a tropical depression could still
form over the next couple of days before the system moves fully
inland by the end of the week.
Regardless of development, heavy rainfall could produce localized
flash flooding over portions of Florida through through today.
Heavy rainfall could also cause flash flooding for portions of the north-central Gulf Coast beginning late today and continuing through
Friday. For additional information, please refer to products issued
by the Weather Prediction Center and your local National Weather
Service office.
* Formation chance through 48 hours...medium...40 percent.

Showers and thunderstorms continue to show signs of organization
in association with a well-defined low pressure area located about
100 miles east of the Cabo Verde Islands. 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 very conducive for later
development, and a tropical depression or tropical storm 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...50 percent.
* Formation chance through 7 days...high...90 percent.
Central Atlantic (AL96):
Disorganized showers and thunderstorms continue in association with
a trough of low pressure located over the central tropical
Atlantic. Some gradual development is possible during the middle
part of this week while the system moves northward over the central
Atlantic.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 7 days...low...20 percent.

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 America:
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.
