...SUPER TYPHOON CHAMPI MOVING WEST-NORTHWEST AWAY FROM GUAM COASTAL WATERS... ...A TROPICAL STORM WARNING AND TYPHOON WATCH ARE NO LONGER IN EFFECT FOR TINIAN AND SAIPAN... .NEW INFORMATION... The Tropical Storm Warning and Typhoon Watch for Tinian and Saipan are cancelled. .AREAS AFFECTED... This local statement provides important information and recommended actions for people in Guam and the Northern Marianas. .Watches/Warnings... A Typhoon Warning continues for Guam and Rota. Although tropical cyclone watches or warnings are not in effect for Tinian and Saipan, possible impacts from related hazards are still a concern. A Flood Watch is in effect for portions of Guam and the Northern Marianas. Please listen closely for any Flood Warnings that might be in effect for your area. Please check the latest public and marine forecasts for detailed information about additional hazards. .STORM INFORMATION... At 11 AM ChST, the center of Super Typhoon Champi (29W) was located near latitude 13.1N, longitude 143.1E. This was about 115 miles west-southwest of Guam. Storm motion was west-northwest, 290 degrees, at 14 mph. Storm intensity was 150 mph. .SITUATION OVERVIEW... Super Typhoon Champi continues to move west-northwestward as the eye pulls away from Guam coastal waters, with its outermost rainbands occasionally crossing the island. Sustained winds hover around or just below damaging tropical storm-force late this morning, with occasional Typhoon-force gusts to around 75 mph. Champi's eye, and the destructive conditions within its compact eyewall, narrowly missed Guam early this morning, passing just 10 miles south of the southern tip of the island at around 4:26 AM ChST. The eye remains compact and very well-defined, with a width of around 5 miles. The islands of Tinian and Saipan are well outside of the radius of sustained tropical-storm force conditions, but damaging gusts to 45 mph are still occurring. The Tropical Storm Warning, and Typhoon Watch, are no longer in effect for Tinian and Saipan. .PRECAUTIONARY/PREPAREDNESS ACTIONS...
Instruction: 
Tropical Storm conditions have been verified on Rota earlier this morning, and tropical storm-force gusts look to continue over the next few hours as Super Typhoon Champi pulls away. Remain alert and stay inside until the all-clear is given. Listen for possible flood warnings.
