Event: 
Typhoon Warning
Urgency: 
Immediate
Effective: 
July 4, 2026 - 10:40pm
Expires: 
July 5, 2026 - 12:45pm
Description: 
* WHAT...A Typhoon Warning remains in effect through at least Tuesday night. * WHERE...Marianas Coastal Waters. * WHEN...Damaging winds expected from through early Tuesday morning. Destructive typhoon force winds expected early Monday morning through Monday afternoon with the passage of Super Typhoon Bavi. * IMPACTS...Sustained winds of near 140 kt with gusts to 170 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 hours as Super Typhoon Bavi (09W) approaches the Marianas. Bavi is maintaining strength at high-end Category 4 to low Category 5. However, there is still uncertainty as to which islands will receive the strongest impacts due to irregular longitudinal shifts in motion. The latest model guidance continues to indicate a path near or just north of Rota, but the forecast track will likely continue to have minor track shifts during the next 24 hours. All of the islands will see impacts. The islands closest to the storm center passage will experience significantly worse conditions.
Instruction: 
Prepare for the imminent passage of a strong typhoon Monday morning. Damaging winds are expected late this afternoon through late Monday night. 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.
