Expires:
October 17, 2026 - 7:45pm
Description:
* WHAT...Tropical storm conditions, including winds of 34 to 63 knots,

more are possible.
* 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, a bit south of Guam, with damaging winds moving into Tinian
and Saipan Waters tonight and lasting into at least Sunday evening.
Champi is expected to strengthen further as it approaches, then move
through the region as a category 4 super typhoon Sunday morning.
Seas are quickly rising, 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 through Sunday night. Secure all vessels. Conditions
are expected to be extremely dangerous for small craft, and dangerous
for any vessels of larger size. As Typhoon Champi approaches the
Marianas, stay in safe harbor.
