* WHAT...Breaking waves between 10 to 15 feet, and occasionally higher, resulting in life-threatening rip currents, beach erosion, and minor coastal flooding. * WHERE...Beaches along the northern coast of Puerto Rico, from Rincon to Fajardo. The most vulnerable areas for high surf, beach erosion, and coastal flooding include Pinones along road 187, Parcelas Suarez, Villas del Mar, and Villa Cristiana in Loiza; Fortuna in Luquillo; Pueblo and Tamarindo in Aguadilla; Barrio Obrero, Pueblo and Jarealito in Arecibo; La Boca in Barceloneta; Machuca in Manati; Puerto Nuevo in Vega Baja; Ocean Park in San Juan; Barrio Espinal in Aguada. * WHEN...For the Coastal Flood Advisory, until Friday afternoon. For the High Surf Advisory, until Friday afternoon. For the High Rip Current Risk, until Saturday afternoon. * IMPACTS...For the Coastal Flood Advisory, shallow flooding of vulnerable areas will result in a limited threat of property and structural damage near the waterfront and shoreline, with a higher threat near the time of high tide. Isolated road closures are possible. 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. * ADDITIONAL DETAILS...A large northwesterly swell is forecast to peak tonight with seas building between 10 and 12 feet around 13 seconds. This will continue to produce large breaking waves and minor coastal flooding along the beaches from northwestern to northeastern Puerto Rico. The next high tides are expected as follows: In San Juan, 2:02 AM AST Friday at 1.30 feet and 12:41 PM AST Friday at 0.67 feet. In Mayaguez, 1:25 AM AST Friday at 0.96 feet and 1:04 PM AST Friday at 0.48 feet.

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 Coastal Flood Advisory indicates that onshore winds and tides will combine to generate flooding of low areas along the shore. A High Surf Advisory means that high surf will affect beaches in the advisory area, producing localized beach erosion and dangerous swimming conditions.
