"If you're not familiar and you're not comfortable with the water with conditions like this, you shouldn't be going out in the water," said Marine Safety Lt. Chris Pierce.
Massive swells were seen along the coast from Ventura to Orange counties. In Seal Beach, 15-feet swells were reported. Some surfers tried to tackle the waves, but the winds made waters choppy in some parts.
"Any time you got this much water coming in, you got to have water going out somewhere," said Michael Donahue of Newport Beach. "If you get caught in the wrong spot, you'll hit the bottom, and all that water is going to suck you back out."
Sandbags were handed out to Seal Beach residents in case of flooding. There was some minor flooding on Electric Avenue and Seal Beach Boulevard, but it has since been cleaned up.
Strong winds also hit the Southland, gusting up to 55 miles per hour in some areas.
