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

    Active Systems:
    The National Hurricane Center is issuing advisories on Tropical
    Storm Cristobal, located over the Atlantic well to the west of the
    Azores.

    Central Tropical Atlantic (AL92):
    Showers and thunderstorms associated with a tropical wave located
    midway between the Lesser Antilles and the west coast of Africa
    have become a little better organized since yesterday.
    Environmental conditions are forecast to be conducive for further
    development during the next day or so, and a tropical depression
    will likely form while the system moves westward to west-
    northwestward across the central tropical Atlantic. Beginning on
    Friday, upper-level winds are likely to become too strong for
    development as the system approaches the Lesser Antilles.
    * Formation chance through 48 hours...high...80 percent.
    * Formation chance through 7 days...high...80 percent.

    Eastern Tropical Atlantic (AL94):
    A tropical wave located a few hundred miles south of the Cabo Verde
    Islands is producing disorganized showers and thunderstorms.
    Environmental conditions are forecast to be generally conducive for
    some development, and a tropical depression could form late this
    week or this weekend while the wave moves westward or west-
    northwestward across the eastern and central tropical Atlantic.
    * Formation chance through 48 hours...low...30 percent.
    * Formation chance through 7 days...medium...50 percent.

    Tropical Depression Cristobal Discussion Number   4
    NWS National Hurricane Center Miami FL       AL032026
    900 AM GMT Thu Aug 13 2026
     
    Recent OSCAT data showed that Cristobal has weaken to a tropical
    depression with max winds around 30 kt. The cyclone continues to
    have a lack of deep convection based on satellite images. The most
    current TAFB intensity estimates with a Final T number of 1.5 and
    maximum winds of 30 kt. As a result, the initial intensity has
    been brought down to 30 kt for this advisory.
     
    Based on the increasingly harsh environmental conditions that the 
    storm is entering as well as the latest model guidance, Cristobal is 
    expected to continue weakening, and it is unlikely that convection 
    will make a comeback.  Thus, the NHC forecast now calls for 
    Cristobal to become a remnant low within the next 12 h, with 
    dissipation following soon after. 
     
    The current motion estimate is east-northeastward, or 075/14 kt.
    The cyclone is expected to turn a bit more northeastward over the
    next 12 h, and barely any changes have been made to the previous NHC
    track prediction.
