ATL: ISAIAS - Post-Tropical - Discussion

[wx98]

MSLP data is nutty on the NOAA plane. Useless...

Based on the even steeper wind drop than the previous pass, I think the pressure might be lower. We’ll have to see what the second plane finds in 15-30 minutes.

I agree. It could be down 2-3 mb possibly.

I have been away from the computer most of the afternoon, so someone probably talked about this earlier. Why does Isaias constantly have the blow up of convection on the west side? Is there a competing vort under that?

If you mean the east side, no there isn’t a competing vort but it is competing for energy and this can slow the rate of intensification. Fairly common in low end northward moving hurricanes, I recall Michael looked like this as it passed Cuba.

Don't know exactly what's going on, but the symmetry is awful. No decent CDO at all right now and it's stretched from north to south.

It kind of looks like it’s still wrapping around a bit. That, or a bit of dry air nibbled the right side of the CDO.

Yet inner core looked solid on radar and recon shows a closed eyewall.

Whatever is happening elsewhere is not disrupting the core yet.

It may just be one of those canes that never becomes a looker. I've seen some really poor looking 65-85kts canes in my time, this far from the worst.

You mean East Side. Left side is the actual CDO (and COC). Good question though and I have no really good answer. One wouldn't think that a fairly deep hurricane would have a secondary mid level feature tethered to it. Often times a hurricane will have a vorticity max near it's core that will rotate around the eye. This other..... appendage? It's not rotating around the storm, and oddly it's not being absorbed "like a feeder band " into the storms structure. In fact, this stupid blob seems to have wrestled away the one true feeder band that was actually feeding into Isaias from the south.

is this where we mention "hurricane" barry?

Good Evening Pete!

Haha I mean, it’s not great but it looks better than it did this morning. Didn’t you say this looked like it was on its way to being a strong hurricane a few pages back, or am I quoting someone else?

[Weatherboy1]

Is it just me or is there a bit more high level outflow/“feathering” of the clouds to the west of the CDO. Not sure if that will help with development but seems like a new trend over last hour or so

[HurricaneEnzo]

I meant Cuba is blocking its inflow Mountains on the SE portion of island.

Apparently Bahamas radar has gone down. Clarence Town on Long Island Bahamas is report sustained winds of 42mph gusts to 59.

Can see the western periphery with a flat look where the trough is cutting off the UL High outflow. This Storm is now at the western edge of it’s UL High and about to get kicked by shear.

Hi Jax!

The G-IV sampled the area around the florida straights and near cuba.

winds from the 500 mb to 250 mb level ranged from 6 to 16 kts out of the WSW..

hardly enough to weaken it. if anything it will strengthen a little more then just maintain till landfall. Unless something changes.

Ask the NHC how that happens.

Bahamas radar is back up!!!

That blob is also something I would like to know about. I has been there for some time and has lots of convection as far as my untrained eye can tell. What's
up with that anyway?
