What's the satilite's cutoff for coloring all that air in brown, in terms of humidity? But that loop is a really good picture of how good it's outflow is, very wispy clouds mark the areas of good outflow. Actcually, I orbserved that outflow when I was following supertyphoon chaba. It's the combo of some shear and excellent outflow that produces very strong tropical cyclones.

Something could form but it is right now unlikely. Surface pressure is high, and the frontal boundary is starting to weaken, but then again you have more cold fronts on the way for some additional lifting, so we'll see then. But for right now looks the rain will continue to push on-shore and end during the night and then start back up again. I would be more concerned with Frances.

I wouldn't be so quick to write this one off. JB just did a midday missive on this system...to paraphrase...

---------------------

Current upward pulse of convection may be for real, and that is what is necessary to begin development. Some evidence a center may start to organize 50 miles east of Charleston. We won't know until tonight, because the convection must get going and stay organized. IF it does so, the outflow forecast is excellent, and it should stay over the warm water and continue to strengthen...At the very least, the potential for torrential rains exists for NC and the rest of the East Coast, with the additional potential for a strike from Frances the following weekend.

---------------------------

JB's been wrong more than he's been right this year, but when he's been right, he's been dead on. I think anyone with interests in the Carolinas, especially the OB, had better keep an eye on this one. First Alex, then Charley, possibly another tropical (subtropical) storm, then possibly Frances...I was actually planning an Outer Banks vacation in September...I hope it's still there.

Todd,

Sorry...it wasn't intentional. BTW, it's "LI" (as in Long Island) Phil, not Lieutenant. Don't feel bad, though, I've also been called Lil Phil too.

BTW, Dvorak's up to 4.0/4.0, so we now have a hurricane on our hands.

This system off of the carolinas is right now ill-defined but in the loops it almost looks like it's almost converging at lower levels. If this system gets going it could become quite strong, JB might be right on this one.

Here's the discussion about the SC disturbance from the Wilmington NWS. Models all over the place, but no real mention of tropical features:
MODELS ARE STILL IN DISAGREEMENT WITH WHAT TO DO WITH THE SYSTEM
OVER THE NEXT COUPLE OF DAYS. THE ETA FINALLY RECOGNIZES THERE IS
INDEED SOMETHING OUT THERE PAST 12 HOURS INTO THE FORECAST. IT TAKES
THE LOW SW INTO N FL. THE GFS TAKES THE SYSTEM WNW UP THE SAVANNAH
RIVER THROUGH SATURDAY. AN ETA SOLUTION WOULD ALLOW MUCH DRIER AIR
TO SLIDE SOUTH AND DRY OUT THE NORTHERN HALF OF THE CWA BEGINNING
FRIDAY. THE GFS SOLUTION WOULD KEEP MUCH MORE OF THE AREA UNDER THE
GUN FOR SHOWERS. WILL SPLIT THE DIFFERENCE FOR NOW SINCE THE ETA WAS
SO UNRELIABLE YESTERDAY AND GO WITH 20-40 POPS MOST AREAS IN THE
SHORT TERM.

Just a thought, is it totally out of the question that Florida, ironically, could get a hit again? I think that would be one for the history books! :?:

It's really never out of the question that Florida could get hit from the low off the southeastern coast but thats like saying what are the odds of getting struck by lighting twice in the same month.

The northewesterly track has begain, it now seems more likely that it will impact the US. I wonder what will happen if Frances comes in contact will the low off of the southeastern coast, very interesting.

The way the forecast track bends to the West reminds me of Andrew's track.

More importantly, every model now takes Frances south of 20/60 and most have Frances well west of 60 before 20N.

Still, the effects of the ridge will have much to do with the whereabouts of Francis by the time it gets near to PR or Hispaniola- if and only if it gets that far south and west.

no... dont think so [Re: WeatherNLU]
      #20899 - Thu Aug 26 2004 03:58 PM

so far today it traveled wnw...then a drop more westerly.. than again wnw

you have to look at the movement over time..
that is how NHC does track so..they will stay with wnw

but... as a storm builds its path is not always fluid and hard to see where the shape of the eye turning distorts what looks like movement

looks like a real stair stepper to me
which makes it harder to figure out

anyone see it slowing down?
Heard this morning that it would begin to be affected by different steering currents and begin to slow down forward progress.. dont see it yet.
