But I think that window is closing fast. These models are just too good at this range to not expect a significant impact from Irma here in Florida. Today's 12z Euro could very well be the nail in the coffin. If it's on course or trends back west some then in my opinion the Florida forecast chapter in Irma's book is nearly completed. From here on out the devil will be in the details. Lots of wobble watching over the next 4 days.


Yeah that window's closing fast. We'll really see where Irma goes by Thursday-Friday for Florida. Of course if the models keep it around SC, the entire state (since it's so small) will definitely need to be on alert. This is definitely a Hugo flashback. Hugo tore up South Carolina but move west of most of North Carolina. Hugo's daughter is coming if the models stay with a SC hit (think Euro also had it hitting SC last run too).

The next Euro run will be significant since GFS did not shift further east...

What an utterly devastating track this is. I don't even want to contemplate it.

The just released GFS run is the worst case scenario for the East Coast of Florida and the entire coast region up.to the South Carolina coast.

The western eye wall would brush or scrape right along much of the coast, which would be catastrophoc with bringing the worst portion closest to shore. This is not good all the way up to Savannah.

This path is very reminiscent of Hurricane David in 1979. But, this time, Irma is much much stronger than David was at the time he was moving parallel to the Florida East Coast and would be moving literally closer right along the coast .

Agreed...The next Euro run will be the most important run of the Euro for Florida and the East Coast since Matthew of last year. It's Euro's hand and it's holding all the cards at the moment.

For what is worth the bipolar CMC also shifted west.

The average of the latest ECME and ECMO (the two best performing models) is exactly where 12Z GFS is.
IMHO, not going to be much more debate.
Miami hit and rake the coast.

SouthFLTropics- with the NHC center saying their errors in day 4 and 5 are 175 to 225 miles on average don't you think
it is still possible for a more westerly movement back over the state especially with not knowing strength of shortwave and
if the high is building back quicker than expected?

Topic is temporarily locked.

Euro runs at 1:45PM, HWRF is running now.

Too much back and forth in here, and frankly I don't care where you think it's going unless you are a model (not that kind of model :) ), or are interpreting a model. There's too much thinking without enough evidence in here and it's not helpful.

It will be unlocked shortly.

12z GFS continues NNW past SFL into GA then NW into W Virginia... No hint of an E component up to W Virginia...

I've noticed the trough seems to be dropping further west of what the GFS an Euro show.

HWRF approaching Andros Island. Most recent runs had the turn happening just after Andros. Let's see what it does this time.

Tracking Irma on the 00z Euro ensembles... I think my dots are pretty close and Irma looks to be just S of the mean consensus line??

I'll say this much. Given the current trend of the models, if I were anywhere from the Carolinas to Long Island I would be watching Irma very closely until, at least, this weekend.
