    Well, well, well. The GFS and GFDL models have a tropical cyclone forming off the SC coast within the next 48 hours. As of tonights' Sattelite run and Quickscat information and the fact that pressures are falling in the this area, it appears that a cyclone may be forming as we speak. NHC has classified this disturbance as Invest 99 and is planning on having a Hurricane Hunter on standby for a possible recon tommorrow.

    Beside all the above, it appears on the Super Long Range that this system may meander just offshore for awhile creating nice SE fetch from it's interaction with a strengthening 1028 ridge sliding SE across Bermuda. Watch out OBX and Mid-Atlantic! IF the models hold true, you may start feeling some pre-runner SE swell of 9 sec@1.5 feet on Thursday. With respect to the best case scenario track, seas are modeled at 12-18 feet and with swell decay of 500 miles or so, the SE swell will increase in size to about 2.5 -4 feet @ 8 secs on Friday into Saturday.

    Keep your fingers crossed. I think that Big Kahuna has made us suffer long enough...see ya out there!

    Showing potential.

    But don't get a head of yourself, the models have been varying quite dramatically with each run.

    GFDL model is showing some real potential this morning.

    PS. The swellinfo model doesn't handle hurricane winds at this point, so if there is tropical development, the forecasts are undercall at this point.

    looks pretty sweet...maybe good waves for the NYBB pro. micah, what makes the models differ from each other? in otherwords why do the gfs, gfdl, etc often contradict each other?

    The GFS is a global model, whereas the GFDL take a small grid of winds that are taken from hurricane hunters and such to model tropical cyclones.

    In such tropical storm cases, the GFDL forecasts generally provide a better picture and are helpful for swell predictions.

    As mentioned, the Swellinfo model can't currently handle the GFDL winds. The best thing to look at for these scenarios is the Wavewatch hurricane model.

    Go to:
    http://polar.ncep.noaa.gov/waves/main_int.html

    Select NAH US coastal zoom, and click on the point forecasts -> NAH stands for North Atlantic hurricane.

    Would like to get a Swellinfo hurricane model going, but that isn't going happen this year unfortunately.

    As of tonight, models still in agreement for a said swell event Friday through Monday. Since I am driving from DC, it still early to begin looking for places to stay along the DelMarVa for the weekend adventure. Currents GFDL model has the system swinging by the Pennisula on Sunday into Monday so you just never know. Just got a new XTR2 board from WRV and I can't wait to use it in some juice.

    When is this thing gonna go Tropical???

    Morning update still says "within a few days"???

    A 1007 MB LOW PRESSURE AREA IS IN THE W ATLC CENTERED NEAR
    29N72W AT 05/0900 UTC WITH A SURFACE TROUGH EXTENDING SW ACROSS
    THE N BAHAMA ISLANDS INTO THE FLORIDA STRAITS. A SECOND SURFACE
    TROUGH EXTENDS NE FROM THE LOW TO 33N68W. THIS SYSTEM HAS
    CHANGED LITTLE OVERNIGHT BUT UPPER LEVEL WINDS ARE EXPECTED TO
    BECOME MORE FAVORABLE FOR DEVELOPMENT INTO A TROPICAL OR
    SUBTROPICAL DEPRESSION THAT COULD DURING THE NEXT FEW DAYS.
    THE
    LOW LEVEL CENTER IS PARTIALLY EXPOSED WITH SCATTERED
    MODERATE/ISOLATED STRONG CONVECTION TO THE E WITHIN 150/180 NM
    OF A LINE FROM THE BAHAMAS NEAR 24N76W TO 31N69W WITH SCATTERED
    SHOWERS/ISOLATED THUNDERSTORMS WITHIN 75 NM ALONG THE E COAST OF
    FLORIDA FROM FORT LAUDERDALE TO JACKSONVILLE.


    Also, the projected path by WW3 and Swellinfo show this thing hugging the coast. I just don't know if I buy that.

    http://www.weather.com/maps/maptype/satelliteworld/tropicalatlanticsatellite_large_animated.html

    If you look at the radar it has definite eastward movement, but yet WW3 48 hr model and swellinfo show it parked on top of Hatteras.

    http://polar.ncep.noaa.gov/waves/main_int.html

    Just seems like a path east of Bermuda is more likely. Either way we get waves, but what do I know.


    Never fear though...
    There are two more tropical waves proving that the sleeping beast in the Atlantic has awoken:

    ...TROPICAL WAVES...

    TROPICAL WAVE IS ALONG 35W/36W S OF 21N MOVING W 10-15 KT. BROAD
    LOW/MID LEVEL INVERTED-V CURVATURE COVERING THE AREA S OF 23N
    FROM 28W-45W OVERTAKING THE 1013 MB LOW EMBEDDED WITHIN THE
    ITCZ. NO ASSOCIATED DEEP CONVECTION WITH ISOLATED SHOWERS FROM
    16N-19N BETWEEN 30W-46W.

    TROPICAL WAVE IS ALONG 67W/68W S OF 21N MOVING W 10-15 KT. WAVE
    IS EMBEDDED WITHIN SOME RATHER DRY STABLE AIR OVER THE E
    CARIBBEAN MASKING THE SATELLITE SIGNATURE AND LIMITING ANY
    SHOWERS/DEEP CONVECTION.

    Wow, GFDL model shows it heading east and strengthening to a Tropical storm tonight then hooking west back towards the east coast on Friday as a Cat 1 'Caine and building up to a Cat 3 on Sunday night!!!

    By the way, the delay time on this site from when you submit a post to when it appears is extremely annoying. But so far this site is worth it.:)
