Hurricane Simon strengthened to Category 4 off Mexico’s Pacific coast early Saturday, Oct. 10, with winds near 140 mph (220 km/h), the US National Hurricane Center (NHC) said. The agency warned of catastrophic wind and life-threatening storm surge along part of the west-central coast. A hurricane warning now covers the stretch from Punta San Telmo to Punta Mita, including the port of Manzanillo and the resort city of Puerto Vallarta.
This is a serious storm. And it’s getting stronger.
The Storm’s Track and Strength
At midnight local time Saturday, or 2 a.m. ET, Simon sat about 140 miles (225 km) south of Manzanillo in Colima state and about 245 miles (395 km) from Cabo Corrientes, the headland at the southern edge of Puerto Vallarta’s bay. It moved north at about 5 mph (7 km/h), with a minimum central pressure of 945 millibars. Category 4 ranks second-highest on the five-step Saffir-Simpson scale.
The system is compact. Hurricane-force winds reach about 15 miles (30 km) from its centre, while tropical-storm-force winds extend about 80 miles (130 km). The NHC expects further rapid strengthening over the next day or so. Its Friday evening forecast discussion projected a peak of about 155 mph (250 km/h) by Saturday evening.
What happens next remains unsettled. Forecasters expect Simon to keep moving north through the weekend, with its centre near or just inland of the coast later Saturday or Sunday. On Friday evening, the NHC said it wasn’t certain whether Simon would push inland over Colima and Jalisco or remain offshore. The agency’s forecast favours landfall, followed by rapid weakening over the mountains, with the storm dissipating by early next week. If its centre stays offshore, Simon would likely retain hurricane strength longer. A hurricane watch reaches north from Punta Mita to El Roblito on the Nayarit coast and includes the offshore Islas Marías.
Rainfall could prove as dangerous as wind. The NHC forecast 10 to 20 inches (25 to 50 cm) across southwestern Mexico, with up to 30 inches (76 cm) in places. It warned that life-threatening floods and mudslides could hit Michoacán, Colima, Jalisco and Nayarit through Sunday.
Government Response
President Claudia Sheinbaum said the armed forces had begun preventive operations and urged people in vulnerable areas to move to temporary shelters, El Informador reported. The government activated the preventive phase of the army’s disaster-relief plan, DN-III-E, alongside the navy’s Plan Marina. Laura Velázquez Alzúa, head of Mexico’s federal civil protection agency, said command centres would open in Jalisco and Colima, Infobae reported.
State and local authorities also moved. Jalisco’s civil protection unit said non-essential activity along the state’s coast would stop from 5 p.m. Saturday, including public transport and petrol stations. Sergio Ramírez López, head of the unit, urged people in risk zones to follow authorities’ instructions. Puerto Vallarta opened five temporary shelters, mostly in schools and university buildings, and said it might add more. In Cabo Corrientes, the coastal municipality south of the city, officials had evacuated about 500 people.
Officials haven’t released a full coastal evacuation count or a date for flights to resume.
Economic Disruption
The commercial impact came quickly. Grupo Aeroportuario del Pacífico (GAP), which operates Manzanillo International Airport, said airlines had cancelled all commercial flights scheduled for Saturday. The airport remained open for general aviation and navy flights if weather permitted, but GAP gave no restart date. Several Puerto Vallarta hotels suspended weekend bookings, El Informador reported. Jalisco’s civil protection unit also asked families and tourists to reconsider coastal trips and contact their airline, hotel or agency.
Markets, meanwhile, were pricing the risk their own way. On Kalshi, a U.S. exchange regulated by the Commodity Futures Trading Commission, bettors gave Simon a 61% chance of reaching Category 5 at 2:14 a.m. ET on Oct. 10, up from 14% a day earlier. The contract pays out only if maximum sustained winds reach 157 mph or more, the Category 5 threshold. About 11,200 contracts had changed hands across Kalshi’s five Simon strength bets, each paying US$1 if correct.
Travel Advisories
The US State Department rates Colima at Level 4, “Do not travel,” and Jalisco at Level 3, “Reconsider travel,” citing terrorism, crime and kidnapping. Its May 29 advisory limits travel in Colima to central Manzanillo’s tourist and port areas and imposes no restrictions for Puerto Vallarta. Travellers should follow Mexican civil protection instructions, check with airlines and hotels, and monitor NHC and Mexican weather service updates.
Why This Matters:
A Category 4 storm bearing down on a coast reliant on tourism and port traffic tests how well a government’s preparations work in practice. Mexico has activated its army and navy relief plans before the storm lands; that’s what those plans are for. Still, the economic exposure is plain: flights grounded at Manzanillo, hotel bookings suspended in Puerto Vallarta, and a coastal economy that stops moving from 5 p.m. Saturday. Uncertainty over landfall means costs could vary widely, from a glancing blow to a direct hit. Private operators such as GAP and local hoteliers are making quick decisions on cancellations and closures, while public agencies manage shelters and evacuations. How quickly services return, and how much damage rain and surge leave behind, will shape the recovery bill for Jalisco, Colima and neighbouring states.
