Typhoon Watch issued October 18 at 9:49AM ChST by NWS Tiyan GU

* WHAT...Tropical storm conditions, including winds of 34 to 63
knots, are expected.

* WHERE...Tinian and Saipan Coastal Waters.

* WHEN...Damaging winds will continue into this afternoon, possibly
longer if Champi slows down.

* IMPACTS...Damaging tropical storm force winds will produce
dangerous seas that could damage, capsize or sink vessels, along
with drastically reducing visibilities in heavy rain.

* ADDITIONAL DETAILS...Super Typhoon Champi (29W) continues to move
quickly away from the Marianas. Champi passed close to the southern
tip of Guam, less than 10 NM, as a strong Category 4 storm. Champi
is expected to strengthen further as it moves through the
Philippine Sea, possibly becoming a Category 5 super typhoon. Seas
are expected to remain hazardous through at least this afternoon,
with significant sea heights as high as 20 feet over western
waters, closest to Champi. Dangerous sea conditions may continue
into Monday.
