Here's a new GARP image with sfc plots. Might be some small low to mid level spin just west of the convection. Comparing its current position (12.5N/58W) to BAM model guidance the past two days - it's MUCH faster and farther south than predicted. Remember, these models assume there is already a well defined LLC, and there isn't one. Just a wave with a trace of spin aloft.
Low-level steering is almost due west. I notice the trend in the BAM models is to the left. Eventually, theyll shift south of Cuba and the DR. Mean mid-level steering is fairly strong and almost due west from the current position. As the system passes well south of Cuba ithis weekend, high pressure aloft builds over the northern Gulf, increasing the easterly flow across the NW Caribbean and BoC. Assuming that a part of the disturbance survives passing the huge TUTT in the central Caribbean, a due west track into Central America and/or Mexico appears most likely.
