Does anyone see a break down of the ridge in 120 hours which allow Tropical Storm Chantal to turn out to sea and not towards Florida. Just an opinion not a forecast.


IF and when the ridge builds back in, Chantal will accelerate and strike the peninsula before anything could materialize, the chances of that happening are low. It is more possible that the ridge does not build in at all and Chantal can follow a trough out to sea, this however has little to no model support.

Intensity, and speed will be key down the line to where exactly it ends up going.

We are probably 45 minutes to an hour away from getting useful observations.

Full euro... though it does not have a closed system the euro takes it into the bahamas stalls it then moves it west just like the other models. pretty good consensus that far out.. only problem is will it survive.. DR

no the center is somewhat exsposed but convection beginning to fire again over center and finally on the north side.

Rock,

You said it in a nutshell- all will be timing- forward speed(or lack of forward speed) and what amount of it's core is intact once it passes the islands. Any change of these rthings can change the whole synoptic set up- Fun days ahead!

So what does everybody think for the upcoming 5pm EST advisory?

Will the NHC show some kind of west bend towards Florida in the forecast track for this advisory?

Will they discuss the possibility of better upper-level conditions in the Bahamas?

I expect a shift to the right at the 5pm advisory due too the GFS shifting to the right. Or the NHC might wait for the next model run and shift it at 11pm if the GFS continues to shift right towards Florida. Just and Opinion not a forecast.

DUN DUN DUN!!!!!!!

Seriously though, the mountains of DR aren't as bad as Haiti. If Chantal moves through the northern part of Hispaniola, it should survive.

I think the NHC will make some sizable changes to the cone at 5pm. More north with a smoother WNW motion throughout (rather than the abrupt NW and NNW motion near the end).

probably both.. though they will likely keep the verbage about not knowing the interaction DR will have.

problem being though the system is quite small and even a little mountain range would likely disrupt the circ.
