A boat capsized in San Francisco Bay on Monday evening, resulting in one confirmed death and three people presumed dead after rescue operations concluded. The incident occurred in waters near the Golden Gate Bridge, prompting an immediate response from the U.S. Coast Guard and local emergency services.

The vessel went down during what authorities described as deteriorating weather conditions. Coast Guard personnel deployed rescue teams to the scene within minutes of receiving the distress call, but rough waters and limited visibility hampered recovery efforts. One body was recovered from the water and pronounced dead at the scene. Three additional individuals remain missing and are presumed dead following an extensive search operation that spanned multiple hours.

Rescue teams conducted a thorough sweep of the affected waters using Coast Guard cutters and helicopters equipped with infrared detection systems. The search area extended across several miles of San Francisco Bay. Despite these comprehensive efforts, rescuers were unable to locate the three missing persons. The Coast Guard made the decision to suspend active search operations after exhausting available resources and determining that further efforts would prove unlikely to succeed.

The Coast Guard did not immediately release the identities of the deceased or missing individuals, citing the need to notify families first. The agency also did not disclose the total number of people aboard the vessel when it capsized or the specific cause of the incident beyond references to weather conditions.

Local authorities in San Francisco and Marin County were alerted to coordinate with federal rescue personnel. The incident marks one of the more serious maritime accidents in San Francisco Bay in recent months. The Coast Guard emphasized that boaters in the region should exercise extreme caution and monitor weather forecasts closely before venturing onto the water.

No additional details regarding the vessel's ownership, registration, or intended destination were available at the time of the report. The investigation into the capsizing remains ongoing, with the Coast Guard conducting a formal inquiry to determine the exact circumstances that led to the tragedy.
