SYNOPSIS
 
Hurricane Sergio, currently centered around 1400 miles southwest of Los Angeles,
is expected to track back to the northeast during the next few days, eventually weakening to a tropical storm and making landfall in central or northern Baja. While most of the moisture from this tropical system is expected to remain south and east of our forecast area, there is the potential for significant hazards in the beach zone later this week as Sergio tracks back into our surf window, bringing a return of large south-southwest swell into our area. The swell that originally brought high surf from Sergio on Friday was from a 170-180 degree direction, which favored the Long Beach area and resulted in some coastal flooding issues. The direction of this new swell energy From Sergio is expected to range between 190 and 210 degrees and is expected to be larger than Friday’s event. This direction favors the large surf to be focused across south and southwest facing beaches from Oxnard to Marina Del Rey, as well as the Central Coast (including Pismo Beach and Port San Luis). Minor coastal flooding issues will be likely near times of high tide for the above mentioned areas Wednesday through Friday, but is not expected to be as great a threat for the Long Beach area due to the change in direction of the swell energy.
