Aviso de tormenta tropical

* WHAT...Tropical storm conditions, including winds of 34 to 63
knots, are expected. Typhoon conditions, including winds of 64
knots or 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 near the southern tip of Guam, with damaging winds moving
into Tinian and Saipan tonight and lasting into at least Sunday
evening. 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 25 feet during closest passage of
Champi. Dangerous sea conditions may continue into Monday.
