The Coast Guard just expanded its security zone around its San Juan base

The US Coast Guard has expanded the permanent security zone around its base in San Juan, Puerto Rico. No vessels or people can enter a 200-foot area around the base without specific authorization.

This is a small, routine change. Military and security installations regularly adjust their perimeters. The Coast Guard is simply making it official that its San Juan base now has a larger exclusion zone. This means boaters and local traffic will need to be more aware of the expanded restricted area.
