The U.S. National Hurricane Center in Miami says Hurricane Patricia's eye has made landfall on Mexico's southwestern Pacific Coast.
The center said the storm had estimated winds of 165 mph (270 kph) when it touched land near Cuixmala. That's still a Category 5 hurricane.
The location is about 55 miles (85 kilometers) west-northwest of the port city of Manzanillo.
Forecasters say the storm is capable of "potentially catastrophic" damage.
