    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:

    Northeastern Gulf:
    An area of low pressure located offshore the east coast of Florida
    is producing disorganized showers and thunderstorms this morning.
    This disturbance is forecast to move westward across Florida during
    the next day or so, and into the northeastern Gulf by late Tuesday. Environmental conditions appear favorable and some gradual
    development of this system is possible while it moves westward to west-northwestward across the northeastern and north-central
    portions of the Gulf during the middle to latter part of this week.
    Regardless of development, heavy rainfall could produce localized

    800 AM EDT Tue Jul 15 2025

    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.

    * Formation chance through 48 hours...medium...40 percent.

    800 AM EDT Wed Jul 16 2025

    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.

    Northern Gulf Coast (AL93):
    Satellite, surface, and radar data indicate that the broad low
    pressure area over northern Gulf is located just south of the coast
    of Mississippi. The associated shower and thunderstorm activity
    remains disorganized and located mainly to the west and southwest
    of the center. Some development could occur before the system moves
    westward into Louisiana later today or tonight, although the
    chances of the system developing into a tropical depression are low.

    Regardless of development, heavy rainfall could produce localized
    flash flooding over portions of the north-central Gulf Coast through
    Friday. For additional information, please refer to products issued

    Storm Dexter, located over the north-central Atlantic Ocean.

    Off the Southeastern United States:
    A weak area of low pressure located a couple of hundred miles off
    the coast of the southeastern United States is producing minimal
    shower and thunderstorm activity. Some slow tropical or subtropical development is possible over the weekend while the system moves
    northward to northeastward, remaining well off the east coast of the
    United States. By early next week, the low is expected to become extratropical, ending its chances for tropical development.

    * Formation chance through 48 hours...low...near 0 percent.
    * Formation chance through 7 days...low...30 percent.

    Central Tropical Atlantic (AL96):
    A tropical wave over the central tropical Atlantic is producing
    disorganized shower activity. Environmental conditions are forecast
    to become more conducive for gradual development in a few days, and
    a tropical depression could form late this weekend or early next
    week while the system moves west-northwestward to northwestward
    across the central tropical and subtropical Atlantic.

    * Formation chance through 48 hours...low...10 percent.
    * Formation chance through 7 days...medium...60 percent.

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

    Off the Southeastern United States:
    A weak area of low pressure located a couple of hundred miles off
    the coast of North Carolina is producing a few disorganized showers
    and thunderstorms. Development of this system, if any, is expected
    to be slow to occur over the next day or two while it moves
    northeastward at 10 to 15 mph. The low is likely to merge with a
    front over the weekend, ending its chances for tropical or
    subtropical development.

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

    Central Atlantic (AL96):
    A tropical wave over the central tropical Atlantic is producing
    minimal shower activity. Development of this system appears
    unlikely during the next day or two due to surrounding dry air, but environmental conditions are forecast to become more conducive in a
    few days. A tropical depression could form during the early
    or middle part of next week while the system moves northwestward to
    northward across the central tropical and subtropical Atlantic.

    * Formation chance through 48 hours...low...near 0 percent.
    * Formation chance through 7 days...medium...50 percent.

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

    Central Atlantic (AL96):
    Disorganized showers and thunderstorms are occurring in association
    with a tropical wave over the central tropical Atlantic. Development
    of this system appears unlikely during the next day or two due to
    surrounding dry air, but some gradual development is possible during
    the early or middle part of next week while the system moves
    northwestward to northward across the central Atlantic.

    * Formation chance through 48 hours...low...near 0 percent.
    * Formation chance through 7 days...low...20 percent.

    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.

    Tropical Weather Outlook
    NWS National Hurricane Center Miami FL
    200 PM EDT Sun Aug 10 2025

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

    Eastern Tropical Atlantic (AL97):
    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.
