we need the 64KT SFMR... flight level winds are not going to get an upgrade as we have surface wind data


It seems this is holding its own, or maybe even strengthening, in spite of the shear it is facing...there was never any data today that supported Hurricane Karen...

the shear vector has turned somewhat this evening from SW to more southerly... may have a UL developing to its SW, making things slightly more favorable

I am impressed that this seems to be right about what we all thought looking at available data- just below hurricane strength.

I have to say, I've been impressed by Karen.

My assertion that this may not become a hurricane, may be wrong.

Shear is still an uncertain variable... but the GFS shows that Karen will be in the right entrance region of a 200mb jet... which will enhance convection.

So even as Karen is sheared, there will still be bursts of convection that will help. And shear may be decreasing in about 5 days.

Not only that, but Karen is looking very healthy with a rather vigorous LLC and impressive outflow (undoubtedly, outflow in eastern quad is right now enhanced by the same TUTT that will eventually shear it).

Last but not least, there is model support for this surviving the trek and becoming a rather impressive system in the central ATL in about a week.

If an ULL forms to its SW, wouldn't that mean a more westward path?

Uhhhh, no. Cat 1 maybe. I would think we see 5-10 knots higher on the N side...so Karen may be at minimal hurricane strength. We'll find out shortly.


You need to consider the average environmental pressure as well. 992mb near the equator won't produce the same pressure gradient as 992mb near 30N. Looks like a moderate TS now, though I think it may have been a hurricane around 12Z.

probably not in this case due to the ridge being weaker to the north

Looks like the shear that has been around for almost all of September will stick around to make sure nothing gets to the United States- or any islands surrounding the U.S. for that matter.

Like Derek said in a post long ago, we may have 15-20 named storms before the season is over.

But, and this is me talking, we still only have three hurricanes and one of them just barely made it in at the buzzer. Not quite what I expected for a raging La Nina season.

However, there is always October and November...right?
