Looks like a low is forming just east of Nicaragua. Definite cc spinning taking place with all the convection to the east of the ill-defined center. If this moves off to the ene as the models indicate it would lessen the impact of the shear a bit, but it would struggle greatly to form in my opinion at this point.

I would doubt that for the time being. The chance of development will be very difficult and increasingly moreso as it travels northeast. However, I could see an STDS issued as it approaches the Greater Antilles simply due to the rainfall potential.

Yes thats what I'm thinking. Regardless of development they are going to issue a STDS if it makes Haiti's mountains continue their movement towards the sea.
Storm2k should gather money for trees to Haiti. Of course the Haitians will burn them for charcoal. Therefore a member will have to guard them for thirty years of so. We could vote on who gets to go.

Yep, shear is high now, but at least the GFS Indicates decreasing shear in 48-72 hours after the low crosses the DR. Lots of rain for the DR through PR Sunday/Monday. I think it may have a 40-50% chance of becoming a TD or Arlene beyond 48-72 hours, even with the shear. Shear would prevent it from becoming a strong storm, however. But it's heading NE and out to sea after moving past the DR.

I can't even go away for a confrence...look what happens when I'm away!
Just looked at the 85H and 37H SSMI imagery from down there...perhaps some curvature...at least at 10am this morning...in the mid levels.
85H: http://152.80.49.216/tc_thumbs/20050513 ... VEST.x.jpg
37H: http://152.80.49.216/tc_thumbs/20050513 ... ST.91L.jpg
Quikscat from early this morning (5AM) shows unidirectional flow near the surface (rain contaminated though) with some 50 knot wind barbs thrown in:

Looks like the GFS is seeing the disturbance in the lower levels and as mentioned before takes it toward Haiti in the next few days as it gets drawn up by west to east flow in the caribbean and lots of troughiness in the Atlantic.
Also...look at that big ol' 500mb trough sweepin' off the EC in 48 hours:
http://www.nco.ncep.noaa.gov/pmb/nwprod ... 0_048s.gif
SST's...also mentioned above...are adequate...
http://www.nhc.noaa.gov/tafb/atl_anal.gif
But as Mr. Pepr notes lots of shear around...of course with all of that upper shear significant tropical development seems unlikely...but betcha we could see some minimal development in the next 48 hours or so.
