20-Foot Waves To Wallop NorCal Coast During ‘Storm Of The Decade’…

A powerful storm system described by forecasters as the “storm of the decade” is expected to whip up large and dangerous surf along the Bay Area’s coastline Thursday through Saturday. A west-northwest swell generated by a storm system in the Gulf of Alaska is expected to arrive by Tuesday as an area of low pressure develops 400 miles west of San Francisco Wednesday night. Seas from the developing system will combine with the distant swell and build to 15-18 feet. Mavericks at Half Moon Bay is likely to see some of the largest waves reaching as high as 27 feet during high tide. Stinson Beach and Ocean Beach could see 11 to 18-foot waves. Swells above 20-feet will develop offshore leading to hazardous conditions for mariners.
