  lying property including parking lots, parks, lawns, and homes 
  adjacent to the waterfront will experience shallow flooding. 
  Dangerous swimming and surfing conditions and localized beach 
  erosion. Rip currents can sweep even the best swimmers away from

unknown depth. Take the necessary actions to protect flood-prone
property.

Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.

Life-threatening rip currents. If caught in a rip current, remain
calm. Swim in a direction following the shoreline. If tired,
float or tread water until out of the rip current. If unable to
escape, face the shore and call or wave for help. 

Shore break occurs when waves break directly on the beach. It is
extremely important to protect your head and neck whenever you
are in breaking waves by keeping your hands in front of you at
all times.
