[SEP 16] Today, there is a moderate risk of rip currents along the north- and east-facing beaches of Puerto Rico, Culebra, and St. Croix. Similar conditions are expected to persist through most of the workweek, so beachgoers are advised to exercise caution at all times, as a moderate risk means life-threatening rip currents are possible in the surf zone. A low risk is expected elsewhere. [16 de sept] Hoy existe un riesgo moderado de corrientes marinas en las playas con orientación norte y este de Puerto Rico, Culebra y Santa Cruz.
