ATL: GORDON - Post-Tropical

[Aric Dunn]

Well, this is escalating quickly..

[galaxy401]

Depending on its track Gordon could move over the infamous Loop Current as well. Could already be feeling the benefits of it.

miami update it been very rainy and wind been picking up very windy day what a week went want dead hurr season past month to so now getting active

[GCANE]

Gordon's COC is tightening nicely. I am confident that he will become a potentially very formidable hurricane.

No doubt.
Lot's of folks were out to dinner on this one.

The air in the low levels is much more turbulent over land, where there is added friction, than over the water. It makes a big difference in low level recon missions.

[floridasun78]

what highest gust you seen from miami area ?

[1900hurricane]

Why would recon not fly over Florida?

Can't be plunking folks on the ground with dropsondes.

Lol. What I’m saying is they don’t have to drop them. They can rely on SFMR.

SFMR can't be used if there isn't any water below. The instrument is designed to objectively estimate surface winds based on sea state.

[fendie]

Maybe the NWS wants to see the radius of winds so they know what's coming for Miami/the east coast of the peninsula soon.

Ah, thanks. Didn’t realize that.

Well, this is escalating quickly..

So much for me getting a nap before work.

[tgenius]

For what it’s worth, the rain has picked up quite a bit in the last 30 mins or so. For awhile was a drizzle but now it’s basically raining pretty hard. Technically speaking we are on the NE side so that is the dirty side.

I have to say, Gordon has begun to capture some of my interest. The developing core is giving me some deja vu to Maria, which also had a core develop rapidly within a radar scope. That one was estimated at landfall to be at a 55 kt intensity, but the 984 mb pressure and the measured 83 kt wind gust make me suspect it was closer to 65 kt at the time.

[tarheelprogrammer]

Looks like a big blow up is coming right on top of the COC by looking at recent IR trends.

[artist]

Is he slowing down a tad, or am I imagining it?

[GCANE]

This'll nail it.

A deeper Gordon, however compact, is likely to indirectly heighten the environmental (background) pressure, that is, strengthen the mid-level ridging to its north, owing to convection-related heating. Given the expansion of outflow in all quadrants, the nascent, small inner core, and the evident, initial formation of a potential CDO, Gordon is very likely to become a solid Cat-1 or even low-end Cat-2 hurricane over the Gulf of Mexico within the next day. A stronger system might also track and make landfall farther W, closer to Slidell, LA/Bay St. Louis, MS, than to Pascagoula/Mobile, AL. This is important to mention, given the small size of Gordon: slight changes in track make big differences in terms of impact(s). My personal estimate for peak and N-Gulf landfall intensity: 75 to 85 knots.

Okay I just woke up and got caught up with everything
