Is this really just a meso?

I'd call that a probable tornado but no debris signature means it was just a rapidly rotating wall/funnel or it was a tornado that did no damage. I'd guess it was the latter because it seems like there's not much around in southwestern Florida.

I see the issued a warning for it now. 3 minutes late but they've got a lot on their plate.

Not too much in the area to really make a debris signature tbh but there should be at least something small.

The beam is looking 2200 feet above ground in that area... so if there was damage, it'd take an EF1 (or so) to throw debris up that high. Gate-to-gate rotation was almost 100 mph... so it is possible that there was a tornado but debris just couldn't make it that high. There's a lot of different things that could cause the tornado to not throw debris up to that height... for example, that strong rotation likely didn't last long and therefore might not have hit anything or the updraft weakened before it could lift something to that height. Mid-level rotation could've been stronger than what was going on at the ground. Unfortunately we'll never know

Do gators give off a debris signature? I mean with the Everglades and all...Gatornados!

Hey, it is possible! I mean, they'd be dead by the time they landed in their new street/lawn/field (hopefully not home)

There's been times where a waterspout comes on shore and causes fish to fly from the sky

From the 5pm discussion:

The pressure on the last Air Force Hurricane Hunter aircraft fix fell to about 952 mb, indicating that Ian is restrengthening over the southeastern Gulf of Mexico. The eye of Ian remains well-defined on visible imagery, although radar data from Key West suggest that an eyewall replacement could be in the initial stages. The initial wind speed is set to 105 kt, matching a blend of earlier SFMR and flight-level wind data. The plane data also showed that the area of hurricane-force winds is growing on the east side of the cyclone.

Disco highlights - 952, 105kt, hurricane winds growing on East side. Moving just east of due north at 9kt. Models keeping it stronger, deeper vertically and faster.  Outflow is impinged on SW side. ERC probably taking place.  Bigger system might be more resistant to shear. Max forecast is still 130

Hurricane Ian Discussion Number  19
NWS National Hurricane Center Miami FL       AL092022
500 PM EDT Tue Sep 27 2022

The pressure on the last Air Force Hurricane Hunter aircraft fix
fell to about 952 mb, indicating that Ian is restrengthening
over the southeastern Gulf of Mexico.  The eye of Ian remains
well-defined on visible imagery, although radar data from Key West
suggest that an eyewall replacement could be in the initial stages.
The initial wind speed is set to 105 kt, matching a blend of
earlier SFMR and flight-level wind data.  The plane data also
showed that the area of hurricane-force winds is growing on the
east side of the cyclone.

Ian is moving east-of-due-north, or 010/9-kt, with occasional
wobbles to the north-northeast.  A track toward the north-northeast
is expected for the next couple of days while it moves between a
ridge over the Bahamas and a trough over the western Gulf of Mexico.
There has been some model convergence this afternoon showing Ian
remaining stronger and vertically deeper through landfall.  This
solution results in a faster track, again adjusted to the southeast,
and the new forecast is moved in that direction. This new NHC track
is close to the corrected model consensus and between the quicker
ECMWF and slower GFS models.  It should be emphasized that this
track remains uncertain, with a typical spread in the steering
features leading to big speed and track differences down the line,
not to mention the oblique angle of approach to Florida. In a few
days, more of the guidance is showing Ian interacting with a
shortwave trough over the southeastern United States, causing the
system to move back over the northwestern Atlantic in the longer
range, before turning northwestward back over land.  The day 3-5
track forecast is also shifted eastward, although significant
re-strengthening is not expected at long range.

The outflow pattern of the hurricane is beginning to be impinged
upon in the southwestern quadrant, a sign that upper-level
southwesterly flow is starting to affect the outer circulation.
While the shear should increase up through landfall, it is just too
close-to-call whether it starts to weaken Ian or not, or whether the
larger system is able to resist the shear.  Additionally, an eyewall
replacement cycle could be in its initial phases, although
predicting these structural changes is extremely difficult.
 The new
forecast is near the last one, a little higher than the consensus.
I should note that whether Ian comes ashore as category 4 hurricane
or a large category 3 after an eyewall cycle, avoiding a large and
destructive hurricane for Florida seems very unlikely, and residents
should heed the advice of local emergency management officials.

The new forecast necessitates a Hurricane Warning for portions of
extreme southwestern Florida, and a Tropical Storm Warning for the
rest of southeastern Florida that wasn't previously under a warning.
Users are reminded to not focus on the exact track as some
additional adjustments to the track are possible. Significant wind,
storm surge, and rainfall hazards will extend far from the center.


Key Messages:

1. Life-threatening storm surge is increasingly likely along the 
Florida west coast where a storm surge warning is in effect, with 
the highest risk from Naples to the Sarasota region. Residents in 
these areas should listen to advice given by local officials and 
follow any evacuation orders for your area.

2. Hurricane-force winds are expected in the hurricane warning area 
in southwest and west-central Florida beginning Wednesday morning 
with tropical storm conditions expected overnight.  Devastating wind 
damage is expected near the core of Ian. Residents should rush all 
preparations to completion.

3. Heavy rainfall will affect most of the Florida Peninsula for the 
next several days, spreading to the rest of the Southeast U.S. by 
Thursday and Friday, likely causing flash, urban, and small stream 
flooding. Considerable flooding is expected with widespread, 
prolonged moderate to major river flooding expected across central 
Florida.

Interesting to see storm(s?) pop up in the eye wall that are so intense that the anvil covers up half the eye. Can't imagine it'll last long given all the subsidence in the eye.

I was thinking the same thing!!!  Anvil-topped hurricane.  Technology is amazing.  Don’t take my satellites away.
