Record levels of sargassum seaweed are washing ashore across the Caribbean, Gulf of Mexico, and Florida, disrupting tourism and creating environmental and economic challenges. On Miami Beach, cleanup crews remove tons of seaweed each morning as visitors contend with foul odors and beaches covered in algae.

Businesses across the region report mounting costs as officials prepare for the peak of the season.
