What WRF? Former ETA/NAM or the HWRF? The WRF only goes out 84 hours, that's prior to recurvature. Besides, the extrapolated track beats the WFR/NAM/ETA most of the time. ;-)

I think because it is at such a highish latitude the models are tending to be in agreement..how many storms at this high up in the atlantic have actually gone on to affect say any portion of Florida for instance..i doubt many.

Forence appaears to be strengthening. Is the center finally under the convection?

These screen shots are from the experimental WRF run by NCAR.

I believe the 4KM version will replace the GFDL when its operational.

Edited - the screens are the 12KM version.

The NCAR WRF-ARW 12km Hurricane Forecast goes out 120 hours... though lately it hasn't been updating. :(

Noticed some cloud divergence out ahead of the storm near 25 N 60 W. Is that a sign of high pressure building or the ULL starting to weaken?

I'm all for Florence using up the peak of the season churning the Atlantic before harmlessly recurving out to sea but she needs to get west past 70 to miss Bermuda.

This is from today's WRF run at that site, which seems to only have data out to 75 hours so far ...

Shows Flo recurving..perhaps more interesting is another (probably spurious) low center moving out of the far SW Caribbean toward the Gomex (NAM seems to like this scenario...since it has forecast other lows over Colombia to do the same thing...perhaps it is having a hard time with the heat low persistent over this area)

18Z GFS is now out to 138 hours. No surprises ... a little faster than the 0Z but pretty consistant on track and synoptics. A little faster and shallower with the trough, but apparently not enough to impede recurvature in any way.

And here's today's AR-WRF run now complete out to 120 hours:

It looks to be a little left of the GFS, but not a lot. And if we look at the mid-levels:

Image

we see that there's no ridge left over the top of the system so the track after this point will be north then veering northeast.

I'm just doing my usual trick of grabbing images from the directory ... I tried using the nifty page they've got for viewing but it doesn't work in Opera.

Here's the directory with today's run: http://www.mmm.ucar.edu/prod/rt/wrf/hur12/2006090600/

I would just note that this model run is from last night, and is almost 24 hours old....

this thing remains quite sheared, though the shear is showing signs of letting up as the outflow is expanding to the NW quad

This thing when it makes it to the western Atlantic, is going to take up much of that part of the basin. It may pass 100 miles west of Bermuda, and still bring hurricane conditions to the island. May need to hit east Nova Scotia or Maine would get some decent winds out of this (maybe close to gale force judging by the model's pressure gradient)
