For Tinian Coastal Waters; Saipan Coastal Waters, from Tiyan, GU

- Where
- Tinian and Saipan Coastal Waters.
- When

- Impacts
- Destructive winds will produce dangerous seas that could damage, capsize or sink vessels, along with drastically reducing visibilities in heavy rain.
- Additional details
- Typhoon Champi (29W) continues to move quickly toward the Marianas. The exact path of 29W remains subject to change. However, guidance supports a passage through Guam coastal waters, with damaging winds moving into Tinian and Saipan tonight and lasting into at least Sunday night. Champi is expected to strengthen further today as it approaches, then move through the region as a typhoon Sunday morning. Seas will quickly rise, with significant sea heights reaching as high as 25 feet during closest passage of Champi. Dangerous sea conditions may continue into Monday.
What to do
Prepare for tropical storm force conditions Sunday morning. Secure all vessels. Conditions are expected to be catastrophic for small craft, and extremely dangerous for any vessels of larger size. As Tropical Storm Champi approaches the Marianas, stay in safe harbor.
