    I would attribute the lack of banding structures to Beryl's young age AND the prominence of the Saharan Air Layer nearby. Hard to expand a moist convective envelope when the desert is a few kilometers away to the north. The MDR is dry, but favorable. There isn't much of a mechanism to push this SAL into the system...yet. If there was one thing that can stop this system from achieving the lofty heights the models currently show, it's the Saharan Dust in tandem with quickening easterlies. 96L may have less of it to deal with if Beryl takes a gulp of it...

    Given the improving presentation this looks like a tropical storm and if this organization continues hurricane watches will certainly be warranted at 11pm.

    New SHIPS run continues with amazingly high probabilities of RI for this region this early in the season, especially the 65 kt/72 hour threshold. Can't be stressed enough that this part of the Atlantic and Caribbean is usually where TCs go to die this early in the year.

    Tropical Depression Two Discussion Number   1
    NWS National Hurricane Center Miami FL       AL022024
    500 PM AST Fri Jun 28 2024
    
    The low pressure system that NHC has been monitoring over the
    central tropical Atlantic has developed sufficiently organized deep
    convection in bands around the center.  In addition, visible
    satellite images show that the circulation has tightened, and the
    center now appears well-defined.  Thus, a tropical depression has
    formed, and the initial intensity is set at 30 kt based on the
    latest Dvorak classifications.  Development this far east in late
    June is unusual, in fact, there have only been a few storms in
    history that have formed over the central or eastern tropical
    Atlantic this early in the year.
    
    The depression is moving westward at 15 kt.  A strong subtropical
    ridge to the north of the system should keep it moving relatively
    quickly westward to west-northwestward during the next few days.
    The system might gain a little more latitude toward the end of the
    forecast period when it nears a weakness in the subtropical ridge.
    There is a fair amount of spread in the model guidance, especially
    in the day 3-5 time frame, due to differences in the strength of the
    ridge and the aforementioned weakness. The NHC track forecast lies
    near the consensus aids and is slightly south of the middle of the
    guidance envelope.  Based on this forecast, the system is expected
    to move across the Windward Islands Sunday night and Monday and
    track across the eastern and central Caribbean Sea through the
    middle of next week.
    
    Typically, the atmospheric environment is unfavorable for
    intensification in this portion of the Atlantic basin in late June.
    However, the overall atmospheric and oceanic conditions appear
    conducive for steady strengthening during the next few days.
    Accordingly, the official forecast calls for strengthening and shows
    the depression becoming a tropical storm tonight or early Saturday
    and then a hurricane before it reaches the Windward Islands. It
    should be noted that some of the model guidance is quite aggressive
    and a fair amount are higher than the official forecast.  For
    example, the hurricane regional models show the system becoming a
    major hurricane and the GFS model shows the system deepening below
    970 mb prior to reaching the Windward Islands.
    
    Key Messages:
    
    1. Tropical Depression Two is expected to strengthen and be a
    hurricane when it reaches the Windward Islands late Sunday night or
    Monday, bringing a risk of heavy rainfall, hurricane-force winds,
    and dangerous storm surge and waves.
    
    2. Hurricane and Tropical Storm Watches will likely be required for
    portions of the Windward and southern Leeward Islands later tonight
    or early Saturday.
    
    3. Interests in the central and western Caribbean should monitor the
    progress of this system.  Users are reminded that there is large
    uncertainty at days 4 and 5 and to not focus on the specific
    details of the track or intensity forecast.

    A few reasons imo

    1) the wave is situated pretty far south, and as a result it’s embedded in a much more moist environment 

    mimictpw_natl_latest.gif

    2) Although there is a significant amount of SAL, it has mostly passed the worst of it. This combined with favorable CCKW passage makes it easier for rising motion and convection across the basin. This is a key part in the anomalously favorable MDR pattern.

    3) There isn’t enough shear and a northerly shear vector to impart the dry air into the system.

    As a result, the environment looks good to excellent for development and maybe even quick intensification eventually, but as you can also see from the images above, there are some potential challenges ahead too. 

    The NHC telegraphing possible hurricane watches soon is a big deal. 

    It’s so jova if they put up hurricane watches in the first advisory 

  7. GET READY BHAIS

    BERYL IS ABOUT TO MOG

     

    2. Central Tropical Atlantic (AL95):
    A low pressure system located about 1400 miles east-southeast of the 
    Windward Islands is becoming better defined and the associated 
    showers and thunderstorms are increasing in organization. If these 
    trends continue, a tropical depression will likely form later today. 
    This system is expected to move westward at 15 to 20 mph and 
    approach the Windward Islands by the end of the weekend, and 
    Hurricane or Tropical Storm Watches could be required for portions 
    of that region tonight or early Saturday. For more information, 
    including gale warnings, see High Seas Forecasts issued by the 
    National Weather Service.
    * Formation chance through 48 hours...high...near 100 percent.
    * Formation chance through 7 days...high...near 100 percent.
    
  8. I asked AI to predict the peak intensity for 95L and it's not looking good, but I am too high inhib to post the full response here that states the peak intensity (they explicitly gave it). However, I can say this:

    Key Factors Influencing Intensity

    1. 850 mb Zonal Wind Anomaly: Indicates low-level shear due to anomalously westerly winds. This could initially challenge development but is less impactful for a well-developed system like 95L/Beryl.

    2. 200 mb Zonal Wind Anomaly: Shows anomalously easterly winds aloft, which favor lower shear and promote anticyclonic flow, aiding in outflow and reducing upper-level shear.

    3. Deep Layer Wind Shear: Predicted to be low along Beryl's path, which is conducive for strengthening, especially with the unusually warm sea surface temperatures (SSTs).

    4. Sea Surface Temperatures (SSTs): Warm SSTs provide ample energy for intensification. Given the temperatures are above average, this will support Beryl’s strengthening.

    5. 200 mb Wind Speed and Streamlines: Presence of an upper-level anticyclone (ULAC) providing favorable conditions for development.

    6. Model Guidance and Intensity Projections:

      • GFDL SHiELD: Predicts significant strengthening with well-defined characteristics.
      • SHIPS Forecast: Indicates rapid intensification potential with increasing maximum wind speed.

     Some of my relatives have a long ago planned cruise that starts over weekend from FL and goes to Yucatan/Caymans through 7/2. But then goes to Jamaica on 7/3, Bahamas 7/5, and then back to FL. I said all good thru 7/2 but Jamaica on 7/3 COULD get tricky and smaller chance of an issue in Bahamas+.

     Any other opinions would be appreciated. Does that sound about right? TIA

     

    Implications for the Cruise:

    1. Until July 2: The cruise through the Yucatan and Cayman Islands should generally be safe, with the storm expected to remain to the south.
    2. July 3 (Jamaica): There is a significant possibility of the storm impacting Jamaica around this date. The models show a potential for the system to be at hurricane strength, which could bring strong winds and heavy rain.
    3. July 5 (Bahamas): The Bahamas could experience effects from the storm depending on its path and intensity. If the storm continues its projected track, it may affect this area, but there is more uncertainty compared to the Jamaica forecast.

  10. Eastern Tropical Atlantic (AL95):
    A tropical wave located several hundred miles west-southwest of the
    Cabo Verde Islands continues to produce showers and thunderstorms.
    This activity is beginning to show signs of organization, and
    environmental conditions are forecast to remain conducive. Thus,
    further development of this system is anticipated, and a tropical
    depression or tropical storm is likely to form over the next couple
    of days while the system moves westward at 15 to 20 mph towards the
    Windward Islands. Interests in the Lesser Antilles should monitor
    the progress of this system.
    * Formation chance through 48 hours...high...70 percent.
    * Formation chance through 7 days...high...90 percent.
