...HIGH RIP CURRENT RISK REMAINS IN EFFECT THROUGH MONDAY AFTERNOON... * WHAT...Life threatening rip currents expected due to breaking waves of up to around 6-7 feet. * WHERE...Northwest to northeast beaches of Puerto Rico including San Juan and vicinity and Culebra beaches. * WHEN...Through Monday afternoon. * IMPACTS...Rip currents can sweep even the best swimmers away from shore into deeper waters.

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.
