    Why are we dissecting 204 hour panels for a storm that hasn't formed yet and is forecast to behave like a drunken frat guy in the Caribbean for 3 days before eventually, possibly emerging into the Gulf? 

    Probably because it's the end of the season with nothing else going on, and we are a board full of weather enthusiasts.

    Not a great look for hurricane weary people but still way out there.  High pressure blocks the out to sea route

    Later in the runs there is a huge high over the eastern part of the US, so it never gets here. Haven't seen the midday Euro yet so can't say anything about that run.

    Ryan Hall stream said that the Hurricane Hunters kind of got stuck in the eye earlier (not sure if this is old news, but I haven't heard of such a thing.)

    I believe it happened once before where they had to fly around in the eye and wait for another mission to look over the aircraft on a flyby because of mechanical issues.

    I want data and not just a picture.

    Hurricane-force winds extend outward up to 60 miles (95 km) from the
    center and tropical-storm-force winds extend outward up to 310 miles
    (500 km).  A weather station at Venice Municipal Airport recently 
    reported a sustained wind of 46 mph (74 km/h) with a gust of 69 mph 
    (111 km/h).  Another observation near Venice Beach reported a 
    sustained wind of 51 mph (82 km/h) with a gust to 66 mph (106 
    km/h).

    Add the NOAA graphic:

    yellow = TS Force

    Red = Hurricane Force

    Plus it is very close to the Yucatan, that has to be causing some issues with strengthening IMHO as an amateur.

     

    This area has cooler water due to more upwelling due to westerly winds. This is what I posted in the Beryl thread. The area extends a bit east of the peninsula and north of it. Throw in some dry air with this and you don't get a lot of deepening. 

     

    The coastal area north of Yucatan has experienced a cooling SST trend from 1982 to 2015 during the upwelling season (May–September) that contrasts with the warming observed at the adjacent ocean area. Different drivers were analyzed to identify the possible causes of that unusual coastal cooling. Changes in coastal upwelling and in sea-atmosphere heat fluxes are not consistent with the observed coastal cooling. The eastward shift of the Yucatan Current observed over the last decades is hypothesized as the most probable cause of coastal cooling. This shift enhances the vertical transport of cold deeper water to the continental shelf from where it is pumped to the surface by upwelling favorable westerly winds.

    Aside, can anyone educate me as to why sea surface temps are always consistently cooler just off the northern Yucatán?

    Hurricane Idalia Discussion Number  11
    NWS National Hurricane Center Miami FL       AL102023
    400 AM CDT Tue Aug 29 2023
    
    Radar data from western Cuba indicates that Idalia is becoming 
    better organized.  Most of an eyewall has formed, with much more 
    curvature in the banding features and overall radar pattern.  
    Satellite imagery also shows the center of Idalia firmly within the 
    central dense overcast.  Thus, the initial wind speed is raised to 
    65 kt, in accordance with the latest TAFB satellite classification.
    
    The hurricane is accelerating northward this morning, now moving at 
    about 9 kt.  Idalia should move faster to the north or 
    north-northeast through landfall on Wednesday between mid-level 
    ridging over Florida and a trough dropping into the western Gulf of 
    Mexico.  There has been a westward shift in the model guidance 
    overnight, perhaps due to the trough tugging Idalia more 
    northward before taking a north-northeast turn.  It should be 
    noted that the ECMWF ensemble shows many of its strongest members 
    on the eastern side of its guidance envelope, which is a 
    reasonable place to be given the synoptic pattern.  The new NHC 
    forecast is adjusted a little to the west but is now east of the 
    model consensus on the eastern side of the reliable model guidance. 
    After Idalia leaves the eastern United States coastline, the track 
    forecast becomes highly uncertain and little change was made to the 
    previous forecast.  
    
    With an inner core now present, the stage is set for Idalia to 
    rapidly intensify before landfall. Shear should continue to lower 
    over the cyclone as an upper-level trough departs the northeastern 
    Gulf of Mexico and ridging builds closer to the cyclone.  These 
    changes, combined with extremely warm and deep waters the hurricane 
    will be traversing, all strongly point to rapid intensification.  
    The new forecast is similar to the previous one, and confidence is 
    increasing in an extremely dangerous major hurricane making landfall 
    Wednesday along the west coast or Big Bend region of Florida.
    
    KEY MESSAGES:
    
    1. There is a danger of life-threatening storm surge inundation
    along portions of the Florida Gulf Coast where a Storm Surge Warning
    is in effect, including Tampa Bay and the Big Bend region of
    Florida. Inundation of 8 to 12 feet above ground level is expected
    somewhere between Chassahowitzka and Aucilla River.  Residents in
    these areas should follow any advice given by local officials.
    
    2. Hurricane conditions are expected within portions of the
    Hurricane Warning area along the Florida Gulf Coast, with the
    potential for destructive winds where the core of Idalia moves
    onshore. Strong winds will also spread inland across portions of
    northern Florida near the track of the center of Idalia.
    
    3. Heavy rainfall is expected across portions of western Cuba and 
    may produce areas of flash and urban flooding as well as landslides. 
    Areas of flash and urban flooding, some of which may be locally 
    significant, are expected across portions of the west coast of 
    Florida, the Florida Panhandle, and southern Georgia beginning today 
    into Wednesday, spreading into portions of the eastern Carolinas 
    Wednesday into Thursday.
