radar beams are not that accurate that far out.... where eye is now... would be shooting up 25ft and higher... so low "surface center" could be just little off.... expect a wobble all night.... shear to me is not all that bad... she's not feeling to much of effect from the second cold front.... yet!
honestly, i don't think shear is going to be that big of a factor with ... she's moving along smartyly with the flow, where as, if she were somehow resisting she'd be more susceptible to shear.. . as long as she keeps moving along and accelerating she's actually more likely to behave as though she were in a light upper wind environment..

Still not much sign from the satellite of any shear adversely affecting at the present time. Upper-level winds are increasing to the north of the system, which is enhancing the outflow to the N and E. Sooner or later, will start to feel more shear from the southwest, but for the next few hours at least it may intensify some more.

yeah... agree and that's not good... i do think she will make it up to cat 3 now... ((low end!))
like others said.... appearance on sats is improving... but would only expect the "core of strong" winds in a small area near landfall... almost like this year.... last year... the main strong winds in a very small area.... well see how she does tonight!

Will someone please plot these cords? Didn't the 18 run just have a shift north? I know how to plot but I dont have a plot form and it's hard on the computer.
Thanks

I just checked the Nexrad Wind Profilers in Southern Florida.
Key West-max of 78kts at 19000ft.
Miami- max of 45kts at 20000ft.
Tampa-max of 58kts at 45000ft.
All of the current winds on the profilers appear to be unidirectional.
Dr Greg Forbes at just displayed One front as Stationary from North of Ft Myers to the Melbourne area.
With SE winds on the south side of the front and NE winds on the North side. Combined with 's wind field this is probably the setup for the spin associated with the Tornado Warnings.
00Z Soundings aren't in as of yet.
12Z soundings from Key West indicated a helicity of near 150m/s/s., and Tampa's helicity was near 100m/s/s.
(I hope I got the m/s/s correct~danielw)

I generally agree with your analysis, though still has some issues to deal with before that happens. Can the eye clear out (still some stubborn old eyewall fragments around the center) and can the eye contract enough to allow for a more rapid deepening? I guess we are about to find out.

...honestly...not intending to toot one's owh horn here but i discussed that in hammered intensity in a lengthy post near the beginning of this thread....
...and, yes, i agree, not only trying to come back but it is uncertain how much that come-back really will be, and therefore, an issue for me that it isn't getting more consideration further n and even w, as the synoptics seem to connote it "should" be gobbled up in the more massive circulation of and her transition into some kind of exotic ne u.s. coastal event..

Here is a link to the Updated Hurricane Local Statements.

Please check them frequently for updates specific to your area.
They are not to replace any other information. Just to localize some of the information.~danielw

...i know...and the trouble is that the 'contracting eyewall' scenario is like the latter half of an - lose analogy because it is unclear much of this strange core appearance was for that cause to begin with... trouble with that is, there is really poor predictive skill for timing contractions and so forth... what she really needs is a burst of deep convection amid the inner aspect, to lower that pressure and drive the wind field tighter in... the 8pm advisory is coming out now so we should get a fix on pp... if we see a 5mb drop we can bet that contraction is either underway or about to begin.

BREAKING NOTE:
Due to the potential of tropical storm force winds associated with Hurricane , all four Walt Disney World Theme Parks, Typhoon Lagoon, Downtown Disney and Disney’s Wide World of Sports will not open tomorrow morning, Monday, October 24. Weather permitting, Walt Disney World may reopen one or more theme parks after the storm passes on Monday to entertain the tens of thousands of Guests currently staying in our resort hotels.

The Weather Channel is reporting that 's wind speed is now up to 110mph.
Her pressure has dropped a little too!
I can't find a link for this yet, but will post it a.s.a.p~danielw
DATA FROM AIR FORCE AND NOAA HURRICANE HUNTER AIRCRAFT THIS EVENING
INDICATE MAXIMUM SUSTAINED WINDS HAVE NOW INCREASED TO NEAR 110
MPH...175 KM/HR...WITH HIGHER GUSTS. IS A STRONG CATEGORY
TWO HURRICANE ON THE SAFFIR-SIMPSON SCALE. ADDITIONAL
STRENGTHENING IS POSSIBLE TONIGHT AND EARLY MONDAY... AND
COULD BE NEAR CATEGORY THREE...MAJOR HURRICANE... STRENGTH AS IT
NEARS THE SOUTHWESTERN FLORIDA COAST MONDAY MORNING.

Pressure steady at 959 mb in the last vortex, though the dropsonde that recorded that pressure measured 15 knots at the surface, so based on that and the drop in 700mb height, the actual pressure is probably 957-958 mb. Still a slow drop, but nothing rapid yet. That is probably still a couple of hours away if it is going to happen.

Hi DanielW... I wrote this in a post earlier in this thread and I believe the reasoning is still quite valid:
It's the extraordinary SRH - Storm Relative Halicity - that is in the area associated with that boundary... Winds across the horizontal depth of the surface trough are backing S to N, from the SSE to the ENE... Compounding, you still have to deal with the conservation of angular momentum by land falling hurricanes, and the local spin ups... Basically what you got there are over-lapping mechanics for twisters... Could be an interesting night; could almost envision tornado swarms...[\i]
