Event:
Typhoon Warning
Urgency:
Immediate
Effective:
October 16, 2026 - 10:37pm
Expires:
October 17, 2026 - 6:00am
Description:
* WHAT...Typhoon conditions, including winds of 64 knots or more
are expected.
* WHERE...Guam and Rota Coastal Waters.
* WHEN...Onset of damaging winds beginning tonight. Onset of
destructive winds after midnight with typhoon force winds early
Sunday morning. Damaging winds will continue into at least Sunday
night, if Champi slows down.
* IMPACTS...Destructive to typhoon force winds will produce dangerous
to deadly 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 near the southern tip of Guam, with damaging winds moving in
late 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 Category 3 typhoon Sunday morning. Seas
are quickly rising, with significant sea heights reaching as high
as 35 feet near the eye wall of Champi. Dangerous sea conditions
may continue into Monday.
Instruction:
Prepare for the passage of a Category 3 or 4 typhoon Sunday morning.
Secure all vessels. Conditions are expected to be catastrophic for
small craft, and extremely dangerous for any vessels of larger size.
As Typhoon Champi approaches, stay in safe harbor.
