The wind was also going to be a problem originally, when Florence was forecast to move inland as a cat3/4, but since then it slowed down and weakened. Even more recent forecasts had Florence making landfall as a cat2.
So the slow weakening of Florence has continued overnight and she is now a category 2 with 110mph winds. She is not classed as a major hurricane anymore. The NHC was expecting her to be a category 4 at this stage and cat 2 at landfall so something has caused her to lose some steam. The main concern of course will be the rainfall especially for Southern Carolina and Georgia.
Florence has weakened a bit compared to earlier today. The winds are down to 120mph. I wonder if this slight weakening trend will continue tomorrow as she gets closer to land.
Yes, the typhoon is much stronger and will not lose speed while Florence although a cat 4 now will lose intensity due to the interaction with the continent once she stalls. By the time she makes landfall she will probably be a cat 2.
Indeed! I think it will depend on the path and influence that Florence makes. For example, the UKMO makes Issac the little satellite of Florence, as she spins him northwards into the Atlantic. The ECM takes him west until he dissipates completely.
The 0z GEM takes Isaak through the Caribbean as a TS and then it becomes a hurricane again as he enters the GOM heading for Texas.
The other models look far less interesting.
Both the Aprege and the GFS so far have shifted Florence's path north and east. The Aprege makes landfall in NC. The GFS out to 96 hours doesn't look like hitting the Carolinas.
The UKMO still takes her to NC.
An area of thunderstorms in the western Caribbean is moving northwestwards and the NHC is giving it a 40% chance to develop into a tropical depression later this week. If it does, i wonder if it can influence Florence's track by throwing a high pressure ridge between the two storms.
The models are currently not making much of this system but this may change in future runs.
The UKMO 12z is back on the landfall scenario.

The Aprege 12z shows landfall on the Carolina's which is also a change to the morning's output.
The UKMO is the only 12z model so far that offers a US landfall. However, it has shifted the part a bit north than the earlier runs.

Edit: The GEM actually also agrees with the UKMO

Lol
The 12z Aprege on the other hand takes Florence to the North Carolina coast although the run finishes when things are getting interesting. Not clear whether it she would make proper landfall or re-curve to the northeast at this stage but it is closer to the coast than ICON.
Looking at this it looks like the only chance for Florence to miss the states is if it takes the more northerly route in the next day or so. If she deepens fast she may do that. The 6z ICON does that and to some extend the Aprege 0z.
The 6z ICON has shifted Florence further north and it seems to be missing the chance for a landfall. This is due to a weaker high to the north.
