I tkink that you want to say 93L not 92L, a mistake surely lol :wink:
92L is the invest near 50W not this one further east

Um, exactly. UK Met tropical product had a couple of Pac systems, and 93L, and nothing at all for 92L.

GFS doesn't really develop this either
I'd say chances have decreased of anything forming quite a bit during the last 24 hours
I agree it looks that the shear has increased over the last 24hrs... but... it looks it might lessen in the next 24hrs, so we will have to watch this closely as it goes into a favorible enviroment.

Following vorticity fields, looks like vorticity from the East merges with 93L, and that is what develops, so this is, sort of, 93L the Canadian develops.
If I try very hard, I can imagine a little curvature near 24ºW, where Canadian has the vorticity that captures 93L and develops.

I think its showing to much weekness in the High pressure.... I think that after a turn to a NW it would move more W after that, the way other models show the Steering Patterns.

right on the heels of 92L. Should both 92L and 93L develop they may take similar paths, in the general direction of the NE Leewards.
For all of those Herbert box watchers, both these invests have a decent chance of making it to the Herbert box based on current model guidance (which is likely to change of course).
It's been since 2004 that a decent looking system has made it into the Herbert box....
I'm really hoping these invests do not develop.

Re: ATL: Invest 93L Model Runs
Although the latest GFS does not develop 93L, it does build a nice ridge over it so I'm not seeing what the GFDL is seeing..

HWRF does not have that turn and it is more intense in that model
GFDL has something off with the steering flow
Rumor has it there is a GFDL model initialized and with BC set by NoGaps? Is that true, and can you tell us what the 'GFDN' is predicting?
