Hurricane Simon brings 150-mph winds and life-threatening flood risk to Mexico’s Pacific coast

Hurricane Simon was moving along Mexico’s Pacific coast Sunday with maximum sustained winds of 150 mph, keeping coastal communities and the resort area around Puerto Vallarta in the path of potentially catastrophic wind, storm surge and flooding.

The National Hurricane Center said Simon’s center was about 60 miles west of Manzanillo and roughly 110 miles south-southeast of Cabo Corrientes early Sunday. The storm was moving north-northwest at about 6 mph, a relatively slow pace that can prolong dangerous conditions near the coast.

Simon’s eye remained just offshore, and forecasters said it was not yet certain whether the center would make a direct landfall. Cabo Corrientes, the western tip of mainland Mexico, was considered the most likely area for a direct hit. That uncertainty matters because a storm tracking parallel to the shoreline can still deliver hurricane-force winds and heavy rain across a broad coastal zone, even if its eye never crosses land.

The immediate danger is not limited to wind. The hurricane center warned of a dangerous storm surge and large, destructive waves near the coast. Rainfall totals of 10 to 20 inches were possible across parts of southwestern Mexico, with isolated amounts of up to 30 inches in Michoacan, Colima and Jalisco. In mountainous terrain, that amount of rain can rapidly overwhelm drainage systems and destabilize slopes, creating risks from flash floods and mudslides well inland from the shoreline.

That combination makes Simon a two-front threat: intense wind and surge for exposed coastal areas, and rainfall-driven flooding for communities along rivers, roads and steep hillsides. The risk also extends beyond the resort zones. Puerto Vallarta is a major tourism destination, but communities between the Sierra Madre and the ocean include residents living in more vulnerable housing and areas with limited evacuation routes.

Authorities in Jalisco suspended classes in 22 coastal municipalities for Friday and Monday and began evacuating people from at-risk areas. Businesses and hotels in Puerto Vallarta boarded windows and placed sandbags as the storm approached. The National Hurricane Center’s hurricane warning covered a stretch of the west-central Mexican coast and the Islas Marías.

The storm’s forecast illustrates why residents should not use the eye’s exact projected path as the sole measure of danger. Simon’s strongest winds, rainbands and coastal surge extend well beyond the center. A modest shift in track could change which communities receive the worst wind, but it would not eliminate the broader risk of flooding and dangerous surf along the coast.

Forecasters expected Simon to remain a major hurricane as it approached Mexico on Sunday, though its intensity could change as the center interacts with land and nearby environmental conditions. The next key developments are whether the eye crosses the coast near Cabo Corrientes, how far inland the heaviest rain spreads, and whether officials expand or adjust evacuation and shelter guidance.

For people in the warning area, the practical message is straightforward: complete preparations before conditions deteriorate, follow local evacuation orders, avoid flooded roads and remain away from beaches, rivers and steep slopes until authorities say the danger has passed.
