Spaghetti models generally agree that PTC 9 will track west-northwest near or over the Leeward Islands, Puerto Rico, the Dominican Republic, and The Bahamas.

Computer models such as UKMET and HWRF, which represent a stronger cyclone, are located on the north side of the guide envelope, while weaker system solutions remain more towards the equator.

The NHC’s updated forecast is similar to the previous notice and lies a little south of the various consensus aids.
