Hurricane Simon was a powerful and erratic tropical cyclone that brushed the coast of Southwestern Mexico. The twenty-first named storm, eleventh hurricane, and ninth major hurricane of the extremely active 2026 Pacific hurricane season, Simon formed on October 7 from an area of low pressure south of Mexico.
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 (249 km/h) and a minimum central pressure of 928 mbar (27.4 inHg). 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.
On October 8, the National Hurricane Center issued a hurricane watch for the Pacific Coast of Mexico from Manzanillo to Punta Mita. Later that day the watches were upgraded to hurricane warnings, with additional tropical storm watches issued around the area. Jalisco Civil Protection ordered all tourist sites to shelter visitors and staff by the afternoon of October 9. The federal Secretariat of Security and Citizen Protection declared a special alert for parts of Jalisco and Colima and set up three command centers headed by Jalisco Governor Pablo Lemus and Colima Governor Indira Vizcaíno. Plan DN-III-E and Plan Marina were put into effect by the Security Secretariat. The Comisión Federal de Electricidad deployed crews to Guerrero to prepare for response to Simon. Schools were closed in 22 municipalities of Jalisco and across the state of Guerrero. Beaches and ports were shuttered in Armería, Manzanillo, and Tecomán in Colima. The Port of Manzanillo also shut down for the hurricane. All non-essential activities in 10 coastal municipalities of Jalisco were prohibited beginning on the afternoon of October 10. About 100 families from the communities of Yelapa and Quimixto were evacuated by ferry to Puerto Vallarta by the Mexican Navy. About 5,000 people evacuated in Jalisco and Colima combined. In Nayarit, the state government prepared 171 shelters for possible evacuations following recent tidal floods in coastal areas.
Governor Greg Abbott of Texas activated emergency resources on October 13 due to the threat of the storm.
Aon plc estimated that losses from Simon totaled to more than US$10 million and that five people were killed by the storm.
