Breaking wave heights and swells are beginning to decrease as 
Post Tropical Cyclone Lee moves away from the region. Therefore,
the HIGH rip current risk has been allowed to expire. However, as
wave heights will still remain somewhat elevated with a long 
period swell around 11 seconds, the rip current risk for tomorrow 
will remain MODERATE.
