Use the BAM models with caution north of 20N and with a system that hasn't developed a deep circulation yet. The BAMM and BAMD are not dynamic models, meaning they don't take into consideration changes in the upper level winds in the future. So these Beta and Advection Models do best in the lower tropics where highs/lows/trofs/ridges don't come into play (or don't move much in 3-5 days).
What they see now are mid and upper-level winds around an upper low over the Yucatan Peninsula, thus the NW track toward the northern Yucatan. But the wave isn't developing/hasn't developed yet. Therefore, it will likely track more to the WNW early on, taking it inland within 24 hours a good bit south of where the BAM models indicate.
My best estimate would be a developing LLC impacting the Yucatan near 19N vs. 21N for the BAMs.
