Event:
Tropical Storm Warning
Urgency:
Immediate
Effective:
October 16, 2026 - 6:12pm
Expires:
October 17, 2026 - 1:00pm
Description:
* WHAT...Tropical storm conditions, including winds of 34 to 63
knots, are expected. Typhoon conditions, including winds of 64
knots or more are possible within the next 48 hours.
* WHERE...Tinian and Saipan Coastal Waters.
* WHEN...Onset of damaging winds beginning late tonight, 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...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.
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.
