Car break-ins common at beach parking and tourist sites
Rip currents cause frequent drownings on the north coast (Isla Verde, Luquillo, Isabela); few lifeguards
Power outages still occur; hotels generally have backup generators

Check official advisories and local flags before swimming. Decomposing sargassum releases hydrogen sulfide; avoid heavy piles.
