Surf: Ana will produce warning level surf of 10-15 ft along south facing shores Saturday and remain elevated through Sunday.
Seas: Ana is expected to produce winds at 30 to 40 mph and seas up to 20 ft across leeward coastal waters Saturday through Sunday. An incoming northwest swell combined with strengthening winds will produce hazardous seas across the remainder of the coastal waters Saturday night and Sunday.
