Let's look at the available information. Chris is talking "possible". Well, most anything is still possible. Likely is fast moving and north of Abaco which would not lead to the surge mentioned. As it passes there it is forecast at 115 mph, so barely a CAT 3 and not close to a 4. My data is as of 7:00 PM. You may actually be in a safer place if it's tied up well and has some ability to float higher without major damage. It's moving at 11 mph. This is based on HWRF, HMON and GFS. GFS is NOAA and is considered excellent in this time range. It has greatly improved over the last few years.
Now, I won't say you can totally dismiss it as ECMWF (European Medium Range) does have a direct hit on Marsh Harbour. In that scenario the strong winds are north of Abaco, but waves are up to 30 feet. However, this model, long considered perhaps the best, hasn't been recently. It missed Florence badly while the others were far more accurate.
