Official alert brief

WHAT

A Typhoon Watch is in effect through at least Tuesday night.

WHERE

Marianas Coastal Waters.

IMPACTS

Winds of near 150 kt with gusts to 180 kt. Seas of up to 45 feet.

ADDITIONAL DETAILS

Typhoon conditions, including winds of 64 knots or more, are possible within the next 48 to 72 hours as Typhoon Bavi (09W) approaches the region. Bavi is undergoing rapid intensification and may approach the islands as a Category 5 super typhoon. However, there is still uncertainty as to which islands will receive the strongest impacts. The latest model guidance continues to indicate a path between Rota and Tinian, 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.

Instructions

Prepare for the passage of a strong typhoon sometime around Monday. Secure all vessels. Conditions are expected to be catastrophic for small craft, and extremely dangerous for any vessels of larger size. As Bavi approaches, stay in safe harbor.
