I saw the same thing. The NNW movement and wobble. I don't think you will hear the media discuss it though. They don't want people to stay on false hope.

Fox 13 out of Tampa is saying that it will drop to a 4 about the time it is north of Haiti and ride in as a 4.

It also said 50 gusts in Tampa, 60 gusts in Zephyrhills, and 70 at my house. It is still too damned early to be telling people this horse shed.

Yep. Now it looks like it's down to 918.

Why do they expect it to weaken when it's going to be passing over warmer water with very little in the way of land masses to disrupt it?

To be fair imo, you dont want this to happen and then have her turn back more westerly because now you are removing more of the Cuba element.

Just enough land interaction plus isn't it supposed to take in some dry air at some point?

Not sure, wind shear maybe? maybe the cooler air that has pushed through the south east

Where do people get the GFS picture graphics that are typically posted? I follow the model runs on Levi's site, but a lot of times individual JPEG's are posted - just curious where I can find those.

The model changed 2nd or first whatever it ends up-- landfall more North of Savannah and Charleston. Anyone know the current (it will change again I know) landfall? Is it more Myrtle Beachish?

lol! Somebody's trolling! That answer was in response to someone in Tampa. As THEY are still in the cone, not LA.

At Levi's site you can create the gif on the bottom. Not all browsers do this. You click 'forecast gif' here LINK and then you add the numbers to the right side of start and end time of the gif. (I always follow Hubba Bubba on here to see the gifs shortly after the model is loaded.)

I wasn't trying to troll. I'll never be comfortable with a storm in the Atlantic basin again

Not saying there's a correlation but here in Jacksonville we have lower humidity than normal. It's also cooler than normal. 79 degrees and low humidity.

Last NHC advisory I saw keeps the winds strong through the Florida approach, though slowly knocking them back along the way.

Short run there's a chance of a true ERC getting going, probably due to some interaction with the mountains of DR/Haiti messing just a little bit with the inflow and circulation. Might be why she's a little wobbly in direction this morning. Dunno if that's the case, it's just speculation.

Down the line there's a decent chance she starts catching some significant enough shear as she hits the big north to weaken her just as she gets the land interaction. Probably won't spare Miami if they get a direct hit but is an early sign of "good" news for Ga and SC.

Another possibility for a wind speed drop and a pressure drop exists if Irma trades the wind speed for overall size and an ever expanding windfield. With more warm water to come it might be the better way to distribute the energy she picks up. Again, speculative on my part.

I'm of a mind she makes a run at 890s on the final approach at Florida. I'm not so sure if this will actually translate to winds any higher than we see now. Not much history to go on with a storm like Irma. Everyone is learning as we go here, even the NHC geniuses.
