Storm intensity was 145 mph. .SITUATION OVERVIEW... The eye of Typhoon Sinlaku (04W) is moving northwest and starting to move away from Tinian and Saipan. Winds up to 145 mph are still found within the eyewall, so winds of excess of 115 mph will continue at Tinian and Saipan for a few more hours, but as the eye moves off to the northwest winds will start to decrease. Tropical Storm force winds extend across Rota and just north of Guam. Tropical storm force winds will be slow to subside across the Marianas due to the size of the storm. Typhoon Sinlaku will begin to pass through the northern CNMI just west of the islands of Alamagan, Pagan, and Agrihan, through the latter half of the week.
