These feature combined are producing up to 12 foot surf along east facing reefs and 10 foot surf along north facing reefs. The high surf advisory may be extend in the afternoon package. The high risk of rip currents is expected through Sunday.

Rip currents will be life threatening. Inexperienced swimmers
should remain out of the water due to dangerous surf conditions.
If caught in a rip current, relax and float. Don't swim against
the current. If able, swim in a direction following the shoreline.
If unable to escape, face the shore and call or wave for help.
