Hurricane Simon intensified into a 150-mph Category 4 storm early Saturday, leaving communities along Mexico’s west-central Pacific coast with a rapidly shrinking window to finish preparations before destructive winds, extreme rainfall and dangerous coastal flooding arrive.
At 6 a.m. Central time on October 10, the National Hurricane Center placed Simon about 120 miles south-southwest of Manzanillo and 220 miles south-southeast of Cabo Corrientes. The storm was moving north at just 5 mph, with maximum sustained winds of 150 mph and a minimum central pressure of 938 millibars.
That makes Simon an exceptionally dangerous high-end Category 4 hurricane. The center’s blunt instruction was that preparations to protect life and property “should be rushed to completion this morning” in the warning area.
A fast-strengthening storm, a slow approach
Simon’s forward motion is slow, but its strengthening has been anything but. The storm’s sustained winds climbed from 110 mph Friday to 145 mph by 3 a.m. Saturday, then reached 150 mph three hours later. That rapid intensification raises the risk that residents will face a much stronger hurricane than they were preparing for only a day earlier.
A hurricane warning covers the coast from Punta San Telmo northward through Punta Mita and onward to El Roblito, including Las Islas Marías. Hurricane conditions are expected within the warning area, while tropical-storm winds can begin well before the center reaches the coast.
The Associated Press reported that landfall is expected late Saturday or early Sunday. Jalisco suspended classes in 22 coastal municipalities and began evacuations in vulnerable areas. Tourism operators in Puerto Vallarta were instructed to move employees and visitors into shelters or other safe locations.
Rain may be the widest threat
The wind forecast is alarming, but Simon’s rainfall could affect a broader area and continue well after landfall. Forecasters expect 10 to 20 inches across parts of Michoacán, Colima, Jalisco and Nayarit, with isolated totals as high as 30 inches.
That much rain falling across steep terrain can trigger life-threatening flash floods and mudslides. Coastal storm surge and large, destructive waves are also expected near and east of the landfall point, where onshore winds can pile water against the coast.
Reuters reported that fishing crews in Manzanillo pulled boats from the beach and authorities placed black flags along the shore to close beaches. The Mexican Navy activated emergency personnel in Colima and restricted maritime traffic, including closing some ports to smaller vessels.
Why Manzanillo and Puerto Vallarta matter
The threatened corridor includes fishing towns, major tourism centers and nationally important infrastructure. Manzanillo is Mexico’s largest port and a central gateway for trade with Asia. Puerto Vallarta is a major international vacation destination with a metropolitan population approaching 300,000.
A direct strike could therefore disrupt far more than the immediate coastline. Port closures, damaged roads, airport interruptions and prolonged power outages could affect regional commerce and travel even if Simon weakens after moving inland.
What people in the warning area should do now
Residents and visitors should follow evacuation instructions from Mexican civil-protection authorities, avoid beaches and low-lying coastal roads, and not attempt to cross flooded streets. People in hillside communities should be especially alert for rapidly rising water, falling rocks and signs of slope movement.
Those outside the warning area should not use the forecast track’s center line as a safety boundary. Hurricane impacts extend well beyond the eye, and the exact landfall location can shift. The latest official position, warnings and forecast cone are available at hurricanes.gov, while Mexico’s National Water Commission publishes local rainfall and coastal updates.
Simon’s next few hours will determine whether the storm strengthens further before reaching the coast. For people in its path, however, the practical message is already clear: the time for planning has ended, and the time for protective action is now.
