Map plotting the storm's track and intensity, according to the Saffir–Simpson scale
On October 3, the National Hurricane Center designated a low-pressure area near the coast of Mexico and Guatemala, stating that it had a 90% chance of development in the next seven days. On October 7, the NHC upgraded the disturbance to a tropical depression, designating it as Twenty-E at 15:00 UTC. At 21:00 UTC the same day, as it was moving northwest, the NHC upgraded the depression into Tropical Storm Simon. The system organized and strengthened over the next day before being upgraded to a hurricane at 03:00 UTC on October 9. However the storm started to move very slowly. The storm continued strengthening and was upgraded to a Category 2 by the NHC. The next day, it rapidly intensified into a Category 3, and later Category 4 major hurricane, while starting to speed up a bit. Its rapid intensification period stopped after that, and started to slowly intensify up to its peak at 06:00 UTC the next day with maximum sustained winds of 155 miles per hour (249km/h) and a minimum central pressure of 928mbar (27.4inHg). After that it started a gradual weakening period as a result of interacting with rugged terrain. The next day it weakened down to a Category 3 major hurricane, and later that day it weakened further into a Category 2. On October 13, a partial scatterometer pass indicated that Simon’s gale-force maximum wind extent only extended out to 30 nautical miles (35 mi), the NHC noted it as a "very small hurricane" as it maintained intensity.
