Note that as a preliminary track, the forecaster just went right between the shallow and mid-layer BAM models. But also note that the dynamic models all turn the system northward to the east of the non-dynamic BAM models.
On satellite, it looks about the same as it has the past day or two now. Exposed low-level swirl with convection sheared off to the east. Winds 10-15 kts around the swirl. Not a TD yet, probably another 24-36 hours to go at least.
Which are more reliable "Dynamic" or "Non-Dynamic"? Would you expect the "OFCI" to shift more N since most of dynamic models are going that way?

Re: INVEST 90L Central Caribbean : Discussions & Images
I should have been more clear - I haven't seen it on radar today, haven't been home, but watched it for quite a while last night. I was finally so intrigued at the persistance of this pattern that at 2:45 this morning I saved a picture of it, at about 16.3N 66.0W. I even drew on the picture which direction the rain clouds were moving - but the NW arrow is wrong, that rain was moving due W. (I was pretty sleepy at that point!
)

Whoops! Looks like I posed the question on the other thread last night at 9:30 or so, should have posted it here!
Anyway, if it's mid-level, would it still cause a drop in surface pressure, or is it still attached to 90L farther west?

Re:
MJ, that is a big discussion around here, too. Many think conditions lately are similar, and that this thing could turn around in a few days time and bite us!caribepr wrote:There are people here wondering about a Wrong Way Lenny scenerio. I'm just waiting to see what happens.

I guess it's just me, but 90L looks to be moving WNW to NW not W to WNW.

For them, it makes no difference if this is named or not. The effects will be the same.

Could have a sheared TS by that time, with the stage set for RI in the Bahamas
Looks like a NW track heading towards Haiti rate now, not sure how the NHC has it moving W to WNW rate now? It won't cross Haiti if it moves W to WNW.

Would this survive a trip across Hispanola?
If so, Florida would probably be out of its sights and it would be well east of us.
