Hurricane Jimena has already uprooted at least one tree in Mexico as it swarms hundreds of miles out in the Pacific.
Forecasters say the dangerous Category 4 hurricane could hit the Baja California peninsula as a major storm in the coming days.
Jimena has spun out rough surf and winds along the northwestern coast. Officials say one couple was forced to spend the night at sea after strong winds kept them from land.
While its affects are already being felt on land, the storm's path is far from certain. The National Hurricane Center in Miami says Jimena "is subject to some uncertainty" and it's difficult to predict exactly how strong the storm will be when it nears Baja.
Authorities in Mexico are setting up shelters in case of heavier wind and rain.
The U.S. hurricane center has issued a public advisory for residents in western Mexico and the southern part of the Baja peninsula to keep tabs on Jimena.
