* WHAT...Life-threatening rip currents due to a long dominant
  period northerly swell. Large breaking waves up to 10-12 feet
  and higher at times.

* WHERE...Beaches along the northwest to northeast coasts of
  Puerto Rico and Culebra.

* WHEN...For the High Surf Advisory, through 6 AM AST tomorrow.
  For the High Rip Current Risk, through Friday afternoon.

* IMPACTS...Dangerous swimming conditions and localized beach
  erosion. Rip currents that can sweep even the best swimmers
  away from shore into deeper water where it becomes difficult
  to return to safety.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

There is a high risk of rip currents.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins, jetties
and piers. Heed the advice of lifeguards, beach patrol flags and
signs.

If you become caught in a rip current, yell for help. Remain
calm, do not exhaust yourself and stay afloat while waiting for
help. If you have to swim out of a rip current, swim parallel to
shore and back toward the beach when possible. Do not attempt to
swim directly against a rip current as you will tire quickly.

A High Surf Advisory means that high surf will affect beaches in
the advisory area, producing localized beach erosion and
dangerous swimming conditions.
