Re: ATL: SEVENTEEN - Models
While an OTS solution is still most likely due to the latitude it will gain by the time it reaches 60W, we'll have to keep an eye on the 500 mb pattern in the SW Atlantic. If the storm is weaker and follows a slightly more southern track near the VI or PR AND mid level ridging builds in about a week per latest Euro, then this storm could threaten Bahamas or east US coast.

Just to be clear, this "OTS solution" literally shows a landfall on Bermuda.

Re: ATL: PAULETTE - Models
Both the 12z GFS and 12z CMC have Paulette remain on the weaker side until 6-7 days out as it nears Bermuda and finds more favorable conditions to intensify. The GFS has a Category 3 hurricane in 9-10 days, which is too far out to take literally, but it suggests Paulette could have a better opportunity to strengthen down the road.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.

Re: ATL: PAULETTE - Models
Gets close to Bermuda this run of the 12Z GFS. Animation starts at hour 132, the storms is well NE of the Lesser Antilles.

12z HWRF makes Paulette nearly into a major hurricane.

Indeed! Here on this 216 hour map of the 12Z EPS, those just offshore the SE US, the TD over FL, and the H in the E GOM are from Paulette:

Re: ATL: PAULETTE - Models
I suspect these models now seen it too weak initially to influence Rene, escape then intensify north of the islands? Basically a Fran or Floyd scenario?

GFS shows Paulette with a donut eye as a likely major hurricane near Bermuda in 7 days or so.

Re: ATL: PAULETTE - Models
Yikes. It’s still within the 10 day range, lots of model
shifts to come.

Re: ATL: PAULETTE - Models
There really isn't too much room for error on the 18z GFS evolution for Paulette. A lobe rotating along the main trough axis is the primary reason it goes offshore this run. Can't assume that will happen 7-8 days out being in a very data sparse region.

I could see that as a possibility. I think we'll get further west shifts before recurvature as the models get a better grip on the interaction between Paulette and Rene, which was obviously overdone. I'm curious what next set of ensembles will show, they've been creeping westwards already.

Re: ATL: PAULETTE - Models
Yeah...that’s a wee bit too close for comfort on the 18z rum.

Re: ATL: PAULETTE - Models
I have my doubts. We saw with Laura the EPS can incorrectly display the ridge as being too strong.
This one screams OTS to me. Bermuda threat at most.

Pretty much, but it does show the evolution of a stronger ridge compared to its prior runs. Which isn’t really good news to be quite honest.
