For hurricane forecasts issued by the NHC, you can see the official error statistics here [0]. Note that 96 and 120-hour forecasts were so poor prior to year 2003 that they were not issued.

Note these error statistics do not represent true model error as the official track and intensity forecast -- while informed by model output -- are determined by human forecasters.
