Is this a zone in Cuba that the US still needs permission to traverse with RECON?
AF98-5307 is entering her center right now, passed right through strongest (NW) eyewall and found top winds of about 120 MPH with pressures up to perhaps low 940s... edit 937.. still flying in

Is it generally true that weaker storms are not effected by troughs as much as stronger storms?

5AM Advisory is out 155/930, but this looks like continuity created before the most recent recon. I'm not really seeing anything in the current pass to support winds above 120 MPH or pressures lower than 935... but, the center is mostly, albeit barely, over 'water.'

"48H 11/0600Z 27.7N 82.4W 105 KT 120 MPH...INLAND"
Maybe, but those coordinates are right at NWS Tampa Bay in Ruskin. Hope the wind shear takes it's toll, but more concerned about a continued west trend, all over water through Apalachee Bay.

Are they afraid people will let their guard down?
We are returning home to Margate, seems like a safe call, winds could be way worst here in Sebring give current track and model guidance.
Traffic on 75 across the Alley looks normal, guess people in Naples aren't running and sheltering in place.

This is definitely looking like one of those rare tracks that will take Irma parallel to the FL west coast, at or just inland. Cuba is taking a toll on Irma's top winds, but the overall circulation still looks good. We can only hope that Irma doesn't re-ignite once over the Florida Straits and SE Gulf. Many of the models, unfortunately, call for re-intensification and there is nothing that should prohibit this in the next 24 hours. I doubt Irma will regain Cat 5 strength, but all bets are off in the warm waters of the SE Gulf. The upper level winds are fairly hostile over the northern Gulf and maybe they will infringe on Irma sooner rather than later. We'll see.
I think the Euro has performed exceptionally well with this system compared to other models (GFS, HWRF) which have consistently been too far north and east. Even the Navgem has done better than those models, though its bias has been too far west. It's looking like a coastal runner up the west coast, unfortunately. My thinking right now is that Irma will weaken to high Cat 2-low Cat3 in the next 12 hours, followed by re-intensification to mid-upper Cat 3 along FL's west coast. The broad circulation may make it more difficult to spin up at the last moment ala . At least that's what I am hoping.

0z Euro shows Irma going fairly well inland into Cuba (more than it actually is, apparently,, watching it closely though) Does not turn it significantly to the north until around midnight. Landfall over Key West mid morning tomorrow Cat 4, Landfall near Port Charlotte/Venice tomorrow night, Cat 4. Over Tampa, Cat 3, then just inland along the west coast passing into Georgia east of Tallahassee. A shift west, but waiting for confirmation of the short term path.
6Z moves Irma a bit more into Cuba, then start the turn north late tonight, Cat 4 landfall west of Marathon Key around noon tomorrow (slower), landfall just east of Naples Cat 4, Near Wauchula Monday morning cat 3 moving toward Gainesville, and into Georgia by Monday evening. More or less just a slight west jog, but very similar to the earlier run.

I certainly agree with you about the Euro. It has been doing a good job all season and the has been almost spot on. With Irma skating a little inland on the Cuban coast, could this possibly take the wind out so to speak in some of the storms sails. Not sure on the lay out of the land area it will be clipping

Cuba certainly is having its effects to Irma. I also still see good symetric outflow on the western half of Irma. Not that usual "wall" associated with a cane making a turn to the north. It is possible that the models will shift west again.

Until the turn happens.. they might slightly.. I think the 12Z might be the last of the west trend in the models (thru landfall) cause the turn should slow start later this evening.

Thank goodness the southern eyewall tangled with the north coast of Cuba this am. Looking a bit better for Port Charlotte/Tampa, still bad for Key West/Everglades City up to Naples. I think the "turn" may end up being sharper than the current forecast when Irma finally pulls away from Cuba given weaker hurricane.

I thought weaker storms are less responsive to troughs. No?

Weaker storms like a TS or low end cat 1 but we are talking about still a 2 most likely a 3 and maybe a low 4 but this is not going to be weak enough for that to happen.

Everything is responsive to troughs.. from a TD to a Cat 5... some people say Cat5 can maybe create it's own steering but that's false.. it can help build up the ridge around it and cause a trough on it's back tail side but it can't just go through a trough..Fronts/troughs are like barriers.

Another west shift. Extreme S FL about to become cone free.
Keys under the gun, followed by the west coast. Very -like except no NE turn this time.

Any reason to expect ANY sort of easterly return going forward?

No.. the main question becomes slowly.. does this thing go of even Clearwater and most of the hurricane force winds just in the keys and along the immediate coast? right now.. no.. it looks on target for a Ft Myers-Naples landfall. 12Z runs of the and Euro-Ukmet will give us the landfall (within 1 dg) in 24-30hrs

The is out the 12Z and is a little more east by a hair then last run. I guess it is showing the Naples landfall
