An Urgent Marine Information Broadcast (UMIB) is a radio safety message the Coast Guard quickly sends out to all boats in a certain area when there may be danger or someone could be in trouble (for example, an overdue vessel, person in the water, or sudden hazard). In U.S. waters these broadcasts are prepared and transmitted by U.S. Coast Guard watchstanders at sector/command centers over VHF and other marine radio systems so nearby mariners can watch for the person or vessel and avoid the hazard.

Coast Guard Sector San Juan is the main Coast Guard command for the Eastern Caribbean. Its area of responsibility is about 1.3 million square nautical miles and includes Puerto Rico and the U.S. Virgin Islands, plus surrounding Eastern Caribbean waters. It is headquartered at Base San Juan and is staffed by U.S. Coast Guard active‑duty personnel, reservists, civilian employees and Coast Guard Auxiliary members, who work closely with Puerto Rico Police, U.S. federal agencies and 26 partner nations.
Coast Guard Air Station Borinquen is a U.S. Coast Guard air base located at Rafael Hernández International Airport in Aguadilla, Puerto Rico. Its primary mission is search and rescue, with additional roles in law enforcement, aids‑to‑navigation support, and logistics. Operationally it falls under Sector San Juan and the Seventh Coast Guard District, and it provides helicopter (and some fixed‑wing) coverage mainly for the waters around Puerto Rico, the U.S. Virgin Islands, and the broader Caribbean region.
The Puerto Rico Police Joint Forces of Rapid Action (FURA, from its Spanish name Fuerzas Unidas de Rápida Acción) is a specialized bureau within the Puerto Rico Police Department. It combines air, maritime, intelligence, and tactical units that work closely with U.S. federal agencies on missions such as drug and weapons interdiction, border and coastal security, and other high‑risk operations across Puerto Rico’s land and surrounding waters.
In international search‑and‑rescue terminology, the “distress phase” is the highest emergency level. Entering the distress phase means rescue coordinators have reasonable certainty that a person or vessel is in grave and imminent danger and needs immediate assistance. At this point, the Coast Guard escalates from concern or alert to full emergency response—committing search aircraft, boats, and other resources on an urgent basis.
