"The Santa Ana winds (sometimes devil winds)[1][2] are strong, extremely dry downslope winds that originate inland and affect coastal Southern California and northern Baja California. They originate from cool, dry high-pressure air masses in the Great Basin." 

"During the Santa Ana winds, large ocean waves can develop. These waves come from a northeasterly direction toward the normally sheltered sides of the Channel Islands, including commonly visited Catalina and Santa Cruz islands. Normally well-sheltered harbors and anchorages such as Avalon and Two Harbors can develop high surf and strong winds that can tear boats from their moorings. During Santa Ana conditions, it is advised that boaters moor on the Southern side of affected islands or return to the mainland."

"In early December 2011, the Santa Ana winds were the strongest yet recorded. An atmospheric set-up occurred that allowed the towns of Pasadena and Altadena in the San Gabriel Valley to get whipped by sustained winds at 97 mph (156 km/h), and gusts up to 167 mph (269 km/h).[22] The winds toppled thousands of trees, knocking out power for over a week. Schools were closed, and a "state of emergency" was declared. The winds grounded planes at LAX, destroyed homes, and were even strong enough to snap a concrete stop light from its foundation.[23] The winds also ripped through Mammoth Mountain and parts of Utah. Mammoth Mountain experienced a near-record wind gust of 175 mph (282 km/h), on December 1, 2011."
