Typhoon Warning

Immediate

Expires: 
July 4, 2026 - 2:45pm
Description: 
* WHAT...A Typhoon Warning is in effect through Tuesday night. * WHERE...Marianas Coastal Waters. * WHEN...Damaging winds expected from late Sunday afternoon through early Tuesday morning. Destructive typhoon force winds expected early Monday morning through early Monday afternoon with the passage of Super Typhoon Bavi. * IMPACTS...Sustained winds of 150 kt with gusts to 180 kt near the center. Seas of up to 45 feet near the storm center. * ADDITIONAL DETAILS...Typhoon conditions, including winds of 64 knots or more, are expected within the next 24 to 48 hours as Super Typhoon Bavi (09W) approaches the region. Bavi, now a Category 5 super typhoon, continues to strengthen and is expected to pass through the Marianas at Category 5 strength. However, there is still uncertainty as to which islands will receive the strongest impacts. The latest model guidance continues to indicate a path near or just north of Rota, but the forecast track will see adjustments over the next 48 hours. All of the islands will see impacts, but the islands closest to the center's passage will experience significantly worse conditions.
Instruction: 
Prepare for the passage of a strong typhoon Monday. Secure all vessels. Conditions are expected to be catastrophic for small craft, and extremely dangerous for any vessels of larger size. As Super Typhoon Bavi approaches, stay in safe harbor.
