I use the NCEP page located below for the NAM and GFS models.

The Canadian and NOGAPS are located here.

The latest model run from the NAM indicates three waves worth watching
in the Western Atlantic by Friday Evening - at least from what I can tell, but I
may be wrong

.

*The first wave, which is also supported by the GFS, is in the central gulf.
*The second is located in the Western Caribbean.
*The third possible area is depicted in the far Northeast Caribbean.

Keep in mind that these solutions are only what the model or models depict
and is not official. Hope this info helps
