Expires:
October 16, 2026 - 2:00pm
Description:
* WHAT...Tropical storm conditions, including winds of 34 to 63
knots, are expected. Typhoon conditions, including winds of 64

* WHERE...Tinian and Saipan Coastal Waters.
* WHEN...Onset of damaging winds beginning Saturday night,
continuing into at least Sunday night, possibly longer if
conditions warrant.
* IMPACTS...Destructive winds will produce dangerous seas that
could damage, capsize or sink vessels, along with drastically
reducing visibilities in heavy rain.
* ADDITIONAL DETAILS...Tropical Storm 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 Saturday night and lasting into at least Sunday night.
Champi is expected to strengthen further today and Saturday 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.
Instruction:
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.
