...HIGH RIP CURRENT RISK IN EFFECT UNTIL 8 PM EDT THIS EVENING...

The National Weather Service in Wilmington has issued a High Rip
Current Risk, which is in effect until 8 PM EDT this evening.

* Location...East facing beaches of northern Horry County.

* Rip Current Risk...High.

* Surf Height...2 to 3 Feet.

* Timing and Tides...Strong rip currents can occur at any time, but
  will be especially prevalent several hours either side of low tide
  which will occurred around Noon.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

There is a high risk of rip currents. Life threatening rip currents
are likely in the surf zone.

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.
