Yeah. I have to chuckle that, based on 11:30 TWO, they're getting ready to upgrade it now.

could it really be more organized then we had thought and could it be going through a ERC since it looks alot worse now and the eye is clouded and everything?

It's not an ERC...it never had a true eyewall to replace anyway. What we're seeing is it transitioning to fully tropical under high shear.

Shear had increased earlier today and, although it is now decreasing, it is generally decreasing gradually. The latest UKMET run now dosn't have much faith in developing it.

It's better than some other runs I've seen this season, though.

SPECIAL FEATURE...
A DEEP LAYERED TROUGH COVERS THE EASTERN ATLANTIC OCEAN.
A 986 MB GALE CENTER IS NEAR 27N41W. A SURFACE TROUGH GOES
FROM 34N34W TO 30N30W TO 24N30W 16N40W 14N46W 15N55W. THE
BROAD CYCLONIC FLOW ACCORDING TO THE ISOBARIC ANALYSIS COVERS
THE ATLANTIC WATERS FROM 16N TO 35N BETWEEN 27W AND 50W. ONE
MIDDLE TO UPPER LEVEL LOW CENTER IN CURRENT WATER VAPOR IMAGERY
IS NEAR 28N32W. A SECOND LOW CENTER IS NEAR 25N41W. THE TROUGH
RUNS THROUGH THIS AREA OF THE ATLANTIC TO 19N44W TO 12N46W.
MIDDLE TO UPPER LEVEL DRY AIR IS ON THE WESTERN SIDE OF THIS
CYCLONIC FLOW NORTH OF 10N BETWEEN 40W AND 70W...COUNTING THE
DRY AIR UNDER THE UPPER LEVEL RIDGE. WIDELY SCATTERED MODERATE
TO ISOLATED STRONG SHOWERS AND THUNDERSTORMS WITHIN 60 TO 120 NM
ON EITHER SIDE OF 24N21W 21N31W 16N40W. SIMILAR PRECIPITATION
CURRENTLY IS FOUND AROUND THE SURFACE CENTER FROM 25N TO 28N
BETWEEN 39W AND 41W. THIS SYSTEM IS CONTINUING TO ACQUIRE
TROPICAL CHARACTERISTICS OVER WARMER WATER...AND IT COULD
BECOME A SUBTROPICAL OR TROPICAL CYCLONE LATER TODAY.

You mean TRYING to transition to tropical status under shear. Also, even though the winds have been increased in the models to 50KT, it still looks less organized than before.

Yep... I know, cycloneye. Still, it looks poorer than yesterday and earlier on current satellite imagery.
