XTRP: This is not a model. It is simply a straight-line extrapolation of the storm's current direction at 2pm Tuesday.
TVCN, TVCX: These are useful, as they are consensus forecasts of global model tracks.
NHC: This is the official forecast from the National Hurricane Center.
TABD, TABM, TABS: These are simple statistical models, which are essentially useless for track forecasting.
NVGM: Useful, but the model is from about 8am ET, or 12 hours before Silver posted the graphic. Wildly out of date.
HMON: This is NOAA's new hurricane model, but it was badly wrong during Hurricane Harvey. Also 12 hours old. Essentially useless.
HWRF: This is NOAA's primary hurricane model, and while it's OK, it is nearly 12 hours old. Not useful.
COTC: A version of the US Navy's global model, which is kind of meh for hurricanes and is 12 hours old.
AVNO, AEMN: Two variants of NOAA's premiere global model, the GFS. Both are worth looking at, but again the forecasts are 12 hours old.
CMC, CEMN: Two variants of the Canadian global model, which is worth looking at, but again the forecasts are 12 hours old.
UKM (also sometimes called UKMET): The UK Met Office's global model, which is definitely worth looking at. But the forecasts are 12 hours old.
CLP5: Not a model at all. Just a forecast based on where storms in this location historically go.

Finally, the world's most accurate model, the European forecast system, is proprietary and not included on such plots.
