...ELEVATED TO LOCALLY HIGH SURF THROUGH SUNDAY...

.The current west swell will continue to diminish into tomorrow, 
but elevated surf may continue overnight particularly in San 
Diego County. After a quieter period Friday afternoon through 
Saturday morning, fresh west and west-northwest swells will once 
again generate elevated to locally high surf conditions late 
Saturday into Sunday. San Diego County looks likely to see the 
highest surf conditions, although favored beaches in Orange County
may also see elevated surf. Will consider High Surf Advisory for 
Sunday.
