The system is now in the southeast Caribbean, south of Puerto Rico, and sporting a very large cold CDO. It has sped up, tracking W at 20kts, and entering a climatologically unfavorable area for development due to strong vertical wind shear (home of the 20-30kt Caribbean low-level jet AND sometimes an upper-level TUTT, or Tropical Upper Tropospheric Trough). However, there is a remote chance that it could develop there (not unprecedented); otherwise, wait until it's through and in the western Caribbean.
With the exception of the temporary increased shear in its near future, conditions are very favorable for intensification to a TS and hurricane during the weekend. The model track guidance suggests a W-WNW path toward Mexico.
An easterly wave on the coast of Africa will also bear watching over the coming days.
