This run is not going to end well for SFL.

As far as intensity verification, we should know in 42 hours or less. Here's the strongest frame prior to crossing Hispaniola.

IMO will end as a Cat 1/2 hurricane near Keys... Big shift in intensity

HWRF being the HWRF, but apparently not seeing any bad conditions.

HWRF exits the DR at 60 hours and never hits terra firma again until the tip of SFL

Some of the models on the18Z runs are showing stronger ridging that tracks the storm further west. South shore of Puerto Rico is still likely to get raked by squalls. After Hispaniola we've seen many storms so torn up that they no longer have sufficient pressure gradient to recover. But if the HWRF is correct and a core reemerges and develops then the ridge evolution is going to be critical since the track will follow the western periphery of the ridge. So south Florida and west coast are targeted this run.

The HWRF strengthens Potential Tropical Cyclone 06L into an 85-knot 979 mb hurricane. Storms in this area are very sensitive to initial conditions, for a subtle change in trajectory could mean the difference between dissipation over Hispaniola and rapid intensification over the warm waters of the Gulf of Mexico.

18z HMON has Fred peak as a high end TS, but it’s further south than the HWRF so the storm runs over the spine of Cuba after Hispaniola and dies.

I am only a meteorology enthusiast who knows a decent amount about tropical cyclones. Look to the professional mets, the NHC, or your local weather office for the best information.
