This is a good point. The 12Z GFS shows a solid NW motion between 24 and 42 hours, as the first trough pulls out, and heights build to the east of the storm. If it fails to move enough today, and starts that NW motion from a lower latitude, could still get close the CFL coast. Lots of time left for things to happen.


Sounds like good news for the Jupiter inlet area north to about Vero. I'm not sure whether the ridge to the north is really going to build in all that much following this first trough lifting out. Seems to me that the weakness will have been established by and large. Perhaps a nudge slightly more back to the N.W.?? Then again, by this time the storm might well be far enough east of the Fla peninsula that a minimal or slight ridge enhanced push to the left might be too little - too late to bring the Dorian less then 40 miles from Titusville. Guess we'll have to wait and see whether a crawl to the N.W. or NNW has already commenced, or whether Dorian will be sitting and feasting on Bahamian Conch fritters for a while longer. Hope it's the former for the sake of those poor people getting raked for endless hours.


Yep, agreed. The ridge I am referring to, is actually to the E of the storm. This is the one that turns it N, but does so with a tilt to the NW for a bit. So it is more the shape of the ridge building from the E than ridging to the N of Dorian. Then, a new trough swoops down and turns it N, then NE. So the NW motion will be temporary, and is the only thing that might shove it back W for a bit. But I agree, looking a little better for FL EC.


Ahh, gotcha. Do you think it would be a matter of the ridge to the east "amplifying" or filling, or in fact moving westward all the while? On another note, thank heaven that this other weak but large disturbance around 27.5N and 65W isn't closer to Dorian then it is LOL. We don't need another player to enter the field adding any further "fuji" downward northerly influence that could result in Dorian to trek any more to the west

Yeah, this link sort of shows it... click through the first few frames, you can see the high build to the E of the storm, and that probably imparts a slight W component for a bit as Dorian moves N: https://www.tropicaltidbits.com/analysi ... 0212&fh=42

Once it begins the turn North, THEN we will be able to officially say that Florida is out of the woods, but not until then.....

JMA displays at low resolution. It never resolved hurricanes to an accurate central pressure. I don’t care to give it much weight in the first place, but when using it at all, don’t pay attention to the specific numbers

Terrible, clueless model normally when it is on its own, which is now the case since the HWRF has abandoned its FL landfalls the last 3 runs.

The HWRF has been behind the curve it seems. This 12Z run is actually the furthest east of any when off FL/GA. So, this joins the consensus of being further east at 12Z when down there. Things continue to look better for FL/GA. But still watching.

Agree. Worth pointing out though, NHC track is on eastern edge of the models shown below.

12z Euro is still persistent that Dorian will move very little over the next 18 hours or so, crawling to the WNW, while the GFS is to the NNW.

The 12Z Euro was initialized further east to reflect on it being east of earlier runs’ projections at Grand Bahama Island. As a result, it’s 36 hour position is a little further east than the last two runs. So, good news to start anyway.

12z Euro is a little further east of 0z & 06z runs, good news, is looking better and better for FL of not getting a direct hit from Dorian.

Indeed. 12Z Euro hour 60 is furthest east of last 4 runs. I think it is due to its starting point being further east. Better for at least FL and GA. :D

Though, you don't think it's looking a tad more west at 48 hours? Course, I'm splitting hairs here if all I'm seeing is roughly a 5-10 mile difference. Like you said though, the important thing is that the major player models are holding steadfast in keeping the storm steadily offshore the Fla. east coast.

1. Vs the last 3 runs, 12Z Euro at hour 48 is clearly further east for the same timeframe.
2. 12Z Euro hour 72 is further east than the last 3 runs off of SC! Could this even miss NC?

showing 945 pressure offshore from Charleston - that seems lower than prev runs

The 12Z Euro at every 6 hours while off FL/GA/SC is further off the coast than the three prior 6 hourly runs. But when it gets to the 96 hour point on the NC coast, it does get close to the 0Z run’s position. Nevertheless, this is a very encouraging run for FL/GA to CHS at least.

Yep, looking better. However, 48 and 72 hour forecasts of TC positions on the Euro can be off by 50 - 100 miles, but yeah, better :-)
