Just towers very little organization.

I assuming any delay will cause Karen to turn W at lower latitude as the HP builds in?

I think the convection burst we are seeing this evening saves Karen...

That is a huge assumption, and the thing that is getting severely underplayed. Jerry is crawling at a snail's pace, while Karen continues barreling forward. I think the likelihood of them interacting is significant

Definitely organizing more with some structured convection. Still sheared of course but holding its own as a TS.

Jerry is accelerating. The two VDMs were .412 degrees and 99 minutes apart. That's 28.4 miles and works out to 17 mph unless I seriously messed up my math.

That is very dubious. Jerry is crawling at 6mph and the NHC suggests this will continue

You can do the math yourself but just look at the recon data. It may have just been a short jog but it did cover nearly half a degree in an hour and a half.

Apologies, your math is fine. I just find that a sudden acceleration is doubtful. If it continues to move that much over several hours that's another story

Convection might be shear or DMAX induced.

One thing the recon has found tonight is a more defined circulation than this morning when it was much broader and they had difficulty centering a COC.

The NHC holds serve keeping Karen a strong TS at day 5 and the west turn... I guess they need a few more model runs to buy into no development after day 4/5...

I guess, but they aren’t model hugging so they are just part of the equation.

They are right in line with the intensity models , so I not sure what you mean

Plane finding TS winds out there with low rain rate, which is fairly surprising to say the least.

What, the TS winds or the low rain rate?

6.3 magnitude earthquake of the north coast of Puerto Rico late Monday evening. No tsunami expected however. Weird event before Karen passing through tomorrow.
