Could change everything
Double landfalls - Irma in Cuba and Katia in Mexico! Irma actually went SOUTH for a bit there, could be a wobble, but she ain't behaving properly. That airport weather station I was monitoring went offline about an hour again, so no ground data on current situation. Models are shifting west again, hugging the western coast of FL now.
From the :
Apparently the ridge to the north of Irma has been stronger than expected, and the initial motion remains westward, or 280/11 kt. The track guidance continues to insist on Irma turning west-northwestward soon, moving along the Cuban Keys adjacent to the north coast of Cuba during the next 24 hours. After that time, Irma is expected to turn sharply north-northwestward and accelerate after 48 hours, moving parallel to the West Coast of Florida and then into Georgia. Mainly because irma's eye has not deviated from its westward motion, the new forecast track has again shifted slightly westward. Because of the hurricane's angle of approach to the West Coast of Florida, it is extremely difficult to pinpoint exactly where the center might move onshore.
Future forecast positions are Cudjoe Key and Fort Myers.

The convection on the northwest side of Irma towards south Florida has really fired up tonight, usually a sign the ridge may be eroding, expect Irma to slow more and start the turn in the morning or so, it's going to be a nail biter to exactly where it makes landfall, but the surge, check the Inundation map (hasn't quite updated for 11 yet) to check if you are in it or not.

I don't think that those mountains in Cuba are strong enough to keep this from coming our way. I just listened to Dr. Knabb and he's saying the same thing. Don't count on Cuba to keep us out of danger. That being said --- if you're not out of the Keys by now..what were you waiting for? SMH.

Might be a wobble, or it might be the beginning of the turn happening now (to my decidedly non-expert eye).

Models are getting less important, but the turn and when it happens is still vital for impact
0Z , turns midday tomorrow, then landfall late Sunday morning just west of Marathon, Cat 5.
Mainland landfall in the late afternoon, cat 5, near Everglades City passes over winter haven, cat 3/4, heads north near Interlachen Cat 3/2. moves nw cat 2 west of Jacksonville, weakening into cat 1 into Georgia up toward Athens, Ga.
This is a shift east for the .
0z UKMET has landfall just west of Marathon also (Over 7 mile bridge) then landfall near Ft. Myers Beach. very slight nudge east of last run.

Trust me, I have no expert eye, either. Could be a wobble..my eyes are just tired. I'm just ready for it to be over.  Just got an alert on my phone that we are now under a hurricane warning from the NWS. I live in Polk County. Not that I haven't been following it...it's just disconcerting. Now looking at it...it looks like it was a little bit of a wobble.

I was thinking the models would switch a little east.My money is splitting the state right in the middle of South Florida.

As we all watch nervously to see where Irma is ultimately going, I thought I'd put out there that for all the grief that the sometimes takes for their forecasts, this advisory from Monday the 4th was pretty darned good when you look at where Irma is at right now and where she's been:

Also looks like the close interaction with Cuba is having a weakening effect, at least in the short term. Irma has yet to make the turn.

Latest (model has outperformed others with Irma) strongly suggests that the cyclone will ride along or just inland of the Cuban coastline for at least another 18 hours or so, and on this track Irma would have some significant and ongoing land interaction. The center would be traveling across lowlands at least off and on - possibly continuously -- and the broader circulation wound likely have at least some disruption from hills. But even on this track, the model shows only modest weakening.
The most recent recon pass found that Irma's pressure has already gone up several millibars, likely as a result of this continued westward track - into portions of Cuba. Given the degradation on satellite, along with the weakening noted in the last recon pass, it is possible that the Euro is understating the amount of weakening that will occur. However, keep in mind that once Irma gets mostly to all back out over water, restrengthening will probably commence, regardless.

We just had a strange and very quick burst of wind here in Northwest Orlando with showers moving from the northeast to the southwest.

I saw several sub 900mb pressure forecasts on one of the model runs earlier. I was using tropicalatlantic.com

I believe she is making the NW turn as we speak. If so, this would her back over water. Need a few more hours to verify. Is this a zone in Cuba that the US still needs permission to traverse with RECON?

It is possible that Irma will experience significant weakening if it tracks with a large portion of the center over Cuba. However, the straits are a very warm section of the Atlantic when it makes the turn. Time and direction will tell.

Irma appears to be totally collapsing over Cuba on the satellite images.

I don't think that Irma is totally collapsing, but I am wondering how much of the weakening will be cited in the 0500 update. It might be too late for the to recognize it.
