The Coast Guard will block off a swim race in Key West

The Coast Guard will create a temporary safety zone for the Florida Keys Community College Swim Around Key West event. During this time, no boats or people can enter the designated area without permission.

This is a routine safety measure for a local event. It means that for a few hours, the Coast Guard will have the authority to keep people and vessels out of a specific part of the water. This ensures the safety of swimmers and spectators during the race.
