Description: 
...SINLAKU UPGRADED TO TYPHOON AND NOW MOVING NORTH-NORTHEAST... .NEW INFORMATION... Tropical Storm Sinlaku has strengthened to a typhoon. A Typhoon Warning has been issued for Fananu, in Chuuk State. .AREAS AFFECTED... This local statement provides important information and recommended actions for people in Guam and the Northern Marianas. .WATCHES/WARNINGS... A Typhoon Watch remains in effect for Guam, Rota, Tinian, and Saipan. A Typhoon Watch means that Typhoon conditions, including winds of 74 mph or more, are possible within 48 hours. A Flood Watch remains in effect for Guam and the Northern Marianas. Please listen closely for any Flash Flood Warnings that might be in effect once flood threats arrive. Please check the latest public and marine forecasts for detailed information about additional hazards. .STORM INFORMATION... At 1 PM ChST...the center of Typhoon Sinlaku (04W) was located near latitude 8.7N...longitude 151.5E. This was about 560 miles southeast of Guam. Storm motion was north-northeast, 25 degrees, at 5 mph. Storm intensity was 85 mph. .SITUATION OVERVIEW... Typhoon Sinlaku (04W) continues to meander in Chuuk State, bringing intense showers, thunderstorms, and winds as it continues to consolidate and intensify. At this time, typhoon conditions are expected at Fananu as Sinlaku now moves slowly to the northeast, followed by a pivot to the northwest on its journey toward the Marianas thereafter. It is too early to provide exact wind and surge forecast values for specific locations in the Marianas, but the general concern should be for the possibility of devastating damage somewhere within the Marianas.
