    Tropical Depression Two Discussion Number 1
    NWS National Hurricane Center Miami FL AL022026
    1000 AM CDT Sun Jul 19 2026

    The area of low pressure that NHC has been monitoring in the
    northeastern Gulf of America during the past few days has now
    developed a well-defined low-level circulation. The convective
    activity remains patchy, likely due to intrusions of dry air from
    its northeast, but there is enough persistent convection near the
    center and in bands on its northeast and southwest sides to justify
    this system as a tropical depression. The circulation is sprawling
    and still weak, however. Based on surface observations and earlier
    ASCAT data, the initial intensity is set at 25 kt and the minimum
    pressure is 1011 mb. The Air Force Hurricane Hunters are scheduled
    to investigate this system later today, and their data will be
    helpful to better assess the system’s initial structure.

    The initial motion of the system is difficult to know since it has
    only recently become well defined, but our best guess is
    north-northwestward at 3 kt. The system is currently caught in weak
    steering currents between a ridge over the western Atlantic, another
    ridge over the south-central and southwestern U.S., and a trough
    over the northeast U.S. This pattern should take the cyclone slowly northwestward through Monday night, and the system will likely be
    close enough to the Florida Panhandle to bring the potential for
    tropical storm conditions there. After that time, a turn to the
    west or west-northwest seems to be the most likely scenario as the
    ridge over the southern U.S. builds eastward, taking the system near
    or across the Gulf coast during the middle and latter portions of
    the week. The NHC track forecast lies a touch to the south of
    middle of the guidance envelope, in best agreement with the usually best-performing aids HCCA, TVCN, and GDMI.

    The sprawling nature of the system, nearby dry air, and some
    northeasterly vertical wind shear suggest that any strengthening
    should be slow to occur, especially in the short term.
    Nonetheless, the system is expected to become a tropical storm as it
    approaches the Florida Panhandle during the next day or two. There
    seems to be a better opportunity for the system to strengthen once
    it turns westward, however, the amount of strengthening will be
    dependent on how far offshore the circulation is. The NHC track
    forecast lies toward the upper end of the model guidance, however,
    there is a low amount of confidence given the uncertainty of how
    much land interaction will take place.

    Key Messages:

    1. The depression is expected to gradually strengthen and
    could bring tropical storm conditions to portions of the Florida
    Panhandle, where a Tropical Storm Watch has been issued.

    2. Interests in Alabama, Mississippi, Louisiana, and
    Texas should monitor the progress of this system, as watches could
    be required for portions of that area over the next day or two.

    3. Areas of flash flooding will be possible through Thursday along
    the eastern and central Gulf Coast from western Florida to southern
    portions of Alabama, Mississippi, and Louisiana.
