Rip Current Statement issued March 14 at 4:33PM AST until March 17 at 6:00AM AST by NWS San Juan PR
* WHAT...High Rip Current Risk, life-threatening rip current. * WHERE...Along the expose beaches in northern Puerto Rico, Culebra, Vieques, and the US Virgin Islands. * WHEN...From Sunday morning through late Monday night. * IMPACTS...Rip currents can sweep even the best swimmers away from shore into deeper water, where it becomes difficult to return to safety.
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.
