Im in Fort Walton/Destin area and storms like this can intensify overnight just  like  Hurricane Opal did back Oct 4 1995 ,  I went to sleep  thinking it would be a cat 1 to wake up to a monstor.  I know it wont be like that but  this one  looks better tonight for sure than it did.... 

i think it will be a little while before significant intensification until the mlc and llc can align, but it sure does looks good I agree.  looks can be deceiving though.

I didn't even have to throw anything together...

 

If you follow Ryan Maue or Joe Bastardi on Twitter, you get even better GFS wind maps tha . t also require no effort.

 

Didn't know it was a contest. If you must know it took a whole 15 seconds to compile in Max and I would certainly take WSI's data feed over that.

 

In any case 97L is looking a lot healthier. Recon sure spent a long time up there

You should really ask Ian or Randy for a Pro tag at some point now that you've been working at WVEC. ;)

If this is shooting through the channel, that means it is going east of the 0Z gfs, which has it hit the corner of the Yucatan. Also, the Euro is obviously going to have a horrible bust, especially considering it did that far west, weak thing run after run.

Folks,
 The 0Z Thu Euro is finally caving into the much more realistic GFS with it having 97L ~100 miles east of its 12Z and earlier runs at hour 42 and significantly more organized with lower SLP vs. its earlier runs. I expect it to come even further east and be even stronger in later runs. It is still ~100 miles west of the 0Z GFS.

 

 

Edit: It is now up to 80% chance from 70% per NHC as of 2 AM.

The Euro (like all models) has had significant issues picking up on the genesis and intensification of small tropical cyclones in the past - good examples are Karl in 2010 and Marco in 2008.

 

It's interesting to see that GFS has done better than the Euro with the genesis and intensity of the most significant Gulf/BOC systems - Barry, Fernand and Ingrid.  It looks very likely that Karen will join that list.

 

The GFS has overdone a few systems that didn't develop because of convective feedback, but its rate of false genesis within 5 days appears to be much less of an issue than in prior years.  It seems recent upgrades have significantly improved the GFS's performance with genesis and TC intensity.

While the 00z ECMWF is completely different on the intensity of 97L the first 24-36 hours, it still decouples the mid-level vortex from the surface circulation thereafter and takes the llc into LA by 66 hours on 18z 5 Oct (Saturday) as a much weakened system. 

 

Ordinarily I'd be willing to trust the ECMWF a lot more, but there simply isn't a strong upper-level trough in the Gulf of Mexico, just a weakening shallow shear axis that could easily be amended by strong diabatic outflow from a TC. I think the GFSs take of 97L is more realistic than the ECMWF's take in which the system's outflow is able to modify the upper-level wind profile enough to mitigate the strongest southwesterly flow. This will still be a sheared TC, but it will be similar to Ingrid, fighting back with attempts to establish outflow.

Not too often we see an invest at 40 knots. That guarantees we'll go straight to a TS once it is classified. Someone's weekend is going to be messed up. Combined with the major winter storm and severe weather event up north, this is turning out to be one heck of a start to October. 

 

At 0600 UTC, 03 October 2013, LOW INVEST (AL97) was located in the North Atlantic basin at 21.5°N and 86.6°W. The current intensity was 40 kt and the center was moving at 11 kt at a bearing of 335 degrees. The minimum central pressure was 1006 mb.
