-  * Long - medium range :+  * Long - medium range : UKMET - The UKMET was the first model to consistently hit the US, while many went OTS and further away. The ECMWF kept recurving the storm too much in its longer range, and the GFS and CMC had a huge range of solutions. ​
  
-  * Short Range :+  * Short Range : HMON - The HMON did just barely better than the HWRF by indicating a Cuban landfall before any other model and then up into Florida before the others, and the HWRF was slower with development overall and failed to predict a monster cat 5 in the Antilles region.
  
-  * Strength :+  * Strength : HMON - Easily beat the HWRF and every other model by creating a monster cat 5 first, but went over a few times too much. The HWRF was much weaker than the HMON was stronger.
