ATL: FLORENCE - Post-Tropical - Discussion

[NDG]

I just calculated how far TS force & hurricane force winds are from the eye based on the latest recon pass.

On the NW quadrant TS force winds reach out 126 miles from the eye, Hurricane force winds reach out 40 miles from eye.
On the SE quadrant TS force winds reach out 100 miles from the eye, Hurricane force winds reach out 38 miles from the eye.

So in another words at minimum TS force winds cover approximately 226 miles in diameter from NW to SE and hurricane force winds approximately 78 miles in diameter from NW to SE.

Edit: Just want to clarify that these were based off of SFMR not from Flight level winds.

With the new outer eye over 50 miles in diameter, I'd say hurricane force winds may now extend out to 60-70 miles from the center. That will decrease today as the eye contracts.

Hard to tell with that jagged eye, but it looks like it’s taking on a slightly more northerly component than earlier. Still WNW, but gaining a bit more latitude than it has been.

Latest microwave pass shows EWRC is near completion with no signs of inner eyewall left

Seems to be having a tough time closing it off to it's N. Hopefully this continues.

Not good, looks to be expanding in size and becoming a much larger major hurricane. Once that new eye pops out, we will likely see more re-strengthening.

Recon found 143kt FL Winds

[FLpanhandle91]

Recon found 143kt flight level winds and evidence of a fairly large eye forming.

[dukeblue219]

Recon is just reaching the center now, with the lowest pressure so far 950.8 and 138kt flight level winds. Peak gust 143kt.

can't find my link to raw recon data. can you post the link please?

I use http://tropicalatlantic.com/recon/recon.cgi but there are others

Check this out..

[GCANE]

Picking up
138 Knot Flight Level

[cjrciadt]

Wow!
High winds for 950mb pressure!

[GCANE]

Rain rate also picking up
65 mm/hr in the clear.
The kind of intensity that can drive it to a Cat 5.

[meriland29]

Her northern bit looks a little behind in terms of gaining up on that convection. Possible problems from ERC?

[supercane4867]

Strong flight-level winds indicate the restrengthening phrase has began. Just need the surface wind to catch up and we will get a 130kt hurricane.

[meriland29]

164 mph?! Really? Unflagged? Would the NHC likely consider that or be generous with her strengthening?
