Please listen closely for any Flood Warnings that might be in effect for your area.

At 8 AM ChST, the center of Super Typhoon Sinlaku (04W) was located by PGUA radar near latitude 14.1N, longitude 146.7E. This was about 130 miles east-northeast of Guam. Storm motion was northwest, 320 degrees, at 7 mph. Storm intensity was 165 mph. .SITUATION OVERVIEW... Super Typhoon Sinlaku (04W) continues to move northwest toward the Marianas, with rain bands of Sinlaku moving south to south- southeast rotating in over the islands, and continuing to bring periods of heavy showers, thunderstorms, and strong winds. The most recent storm track produced by the Joint Typhoon Warning Center (JTWC) has shifted slightly north but continues to favor the center of Sinlaku passing near or over Tinian and Saipan, potentially north of Saipan. While Sinlaku is forecasted to gradually weaken the next few days, it is expected to cross the Marianas near or over Tinian and Saipan as a Category 4 typhoon.
Instruction: 
People should be in a designated shelter or in a sturdy and reinforced concrete building to ride out the storm as tropical storm force winds are occurring and will be increasing through the day. Due to the size of the storm, tropical storm force winds are expected to continue into Wednesday night. Even when winds start to decrease, remain indoors until the government of Guam gives the "all clear".
