.STORM INFORMATION...

At 2 PM ChST, the center of Super Typhoon Sinlaku (04W) was

located by PGUA radar near latitude 12.6N, longitude 148.2E. This

was about 230 miles east-southeast of Guam. Storm motion was

west-northwest, 300 degrees, at 8 mph. Storm intensity was 180

mph.


.SITUATION OVERVIEW...

Super Typhoon Sinlaku (04W) continues to move west-northwest

toward the Marianas with a slight northwest turn expected. The

outer rain bands of Sinlaku are beginning to rotate in over the

islands, and continue to bring periods of heavy showers,

thunderstorms, and strong winds for the far outer islands of

northwest Chuuk. However, tropical storm winds of 39 mph or

greater have moved away from Ulul. The most recent storm track

produced by the Joint Typhoon Warning Center (JTWC) has shown a

slight northward shift in the storm path during its passage toward

the Marianas, still maintaining a track north of Rota and near or

over Tinian and Saipan. Sinlaku is expected to gradually weaken

the next few days, but still expected to cross the Marianas as a

category 4 or 5 typhoon.
