The GFS has a very weak trough pick the system. If the trough is weaker or 91L is further south then I don't think 91L goes up the east coast. Also as is typical of the GFS it has 91L moving NW into a 500mb high pressure when it would normally head more westerly. Will be interesting to see what the EURO and the 12Z GFS ensembles have to say.

It does really slow down also before moving north. Looks like a run that points to future runs trending west.

This goes into the Caribbean, although weaker than other models but it looks like tries to organize once there.

Leading one looks to be Caribbean bound.

91L's percentages are up just a little 10/30%.

An area of disturbed weather located to the southeast of the Cabo

Verde Islands is associated with a tropical wave. The wave is

forecast to merge with a broad area of low pressure located

southwest of the Cabo Verde Islands in a day or two. Environmental

conditions are expected to become more conducive for development of

this system later this week while it moves westward at about

15 mph over the tropical Atlantic.

* Formation chance through 48 hours...low...near 10 percent.

* Formation chance through 5 days...low...30 percent.

Yeah this is way different. Here is the 12z Euro with a Caribbean cruiser from the leading wave which the NHC currently says will merge with the second wave (what the Euro and other models showed developing last run, seen here further northeast).

Yes. You'll be getting out a few days ahead of any threat if 91L were to head that way.
