06 GFS… Notice it shows a little E jog after landfall, I think the GFS landfall point was a bit N of Ian now, but it appears Ian is moving slowly @ENE?

Should be interesting trough is weakening and high pressure ridge in place.

Intensity is underdone, of course. That may play into how it interacts. I’m concerned it may not weaken to below hurricane strength as it moves through the state.

Knew it as soon as I saw Hmon and Hafs book it due east in their last run. I think ultimately the east trend may settle around Hatteras, which is not good considering more time over water.

The UKMET did well with Ian. So the UKMET doesn’t have Ian moving NW after emerging into the Atlantic?

I never bought NW, very unusual trajectory for our area with a gulf storm. I think the turn will eventually be made, but not nearly as sharp as initially forecast.

Indeed, per history, a sharp NNW to NW turn into the SAV-CHS corridor and then well inland after a NE crossing over FL would be pretty close to unprecedented at least since 1851. That doesn't mean it can't happen, of course. But climo/history says to not bet too heavily on it if it is showing up a few days out on models. Let's see if the 12Z Euro changes their tune on this. The non-Euro/GFS model consensus is at least hinting at a trend away from this NW turn.

Re: ATL: IAN - Models
10 yrs ago i remember laughing about the HWRF always being the overdramatic one, but the last 5 yrs, theyre over the top bullish predictions seem to be more and more accurate.

It would need to immediately go NE right now for this angle to verify. As of now satellite is still showing NNE.

Radar appears to be NE. Satellite is hard to track at times. Use radar whenever available.

The 12Z Euro appears to be subtly latching on a correction at least somewhat in the UKMET direction with a SE coast landfall that may now be further north than Savannah at least. I'll have to see the detailed maps later.

I was largely wrong as the detailed 12Z Euro 6 hour maps still show a SAV/Hilton Head landfall.

Re: ATL: IAN - Models
There are many EPS members that show reintensification before another landfall into South Carolina. The forecasting aspect of this isn't done yet, and posters in the Carolinas should keep an eye on this.
