* WHAT...For the High Surf Advisory, large breaking waves of 8 to 12 feet. For the HIGH RIP CURRENT RISK, life-threatening rip current. * WHERE... For the HIGH SURF ADVISORY, the most vulnerable areas for high surf and beach erosion include Pinones along Road 187, Parcelas Suarez, Villas del Mar, and Villa Christiana in Loiza; Fortuna in Luquillo; Pueblo and Tamarindo in Aguadilla; Barrio Obrero, Pueblo and Jareaito in Arecibo; Las Boca in Barceloneta; Machuca in Manati; Puerto Nuevo in Vega Baja; Ocean Park in San Juan; and Barrio Espinal in Aguada. For the HIGH RIP CURRENT RISK Beaches of northern, western and eastern Puerto Rico. * WHEN...For the High Rip Current Risk remains through late Monday night. For the High Surf Advisory now until 6 AM AST Monday. * IMPACTS...FOR THE HIGH SURF ADVISORY, High waves that can wash over jetties and sweep people and pets onto jagged rocks. Rough surf may also knock you down. Large breaking waves will result in localized beach/dune structure erosion and dangerous swimming conditions. FOR THE HIGH RIP CURRENT RISK, 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. A High Surf Advisory means that high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous swimming conditions.
