The hurricane's maximum sustained winds Monday afternoon were near 150 kph, according to the US National Hurricane Center. Dora was expected to begin weakening today.
The hurricane was centered about 285 kilometers southwest of Manzanillo, Mexico, and was moving west-northwest near 21 kph.
The hurricane center said Dora's forecast track shows its center moving away from Mexico's southwestern coast. But swells from the storm are affecting parts of Mexico's coast and are expected to cause life-threatening surf and rip current conditions.
