...HIGH RIP CURRENT RISK IN EFFECT UNTIL 9 PM CDT THIS EVENING...
The National Weather Service in Houston/Galveston has issued a
High Rip Current Risk, which is in effect until 9 PM CDT this
evening.
* TIMING...Today.
* IMPACTS...Hazardous swimming conditions will occur along Gulf-
facing beaches, especially near piers, jetties, and rock groins.
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. Swim near a lifeguard.
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.
