.SITUATION OVERVIEW...
The eye of Typhoon Sinlaku (04W) is moving slowly northwest and the
outer edge of the eye is well northwest of Tinian and Saipan. Typhoon
Sinlaku has been slow to move tonight and has simultaneously
expanded the wind field. This has kept Guam within the tropical storm
force winds and Saipan and Tinian in the destructive tropical storm
force winds through the night. Typhoon Sinlaku will begin to pass
through the northern CNMI just west of Alamagan, Pagan, and Agrihan
today and tonight, forecasted to curve northeastward, passing north
of Agrihan Friday.
Instruction:
People should remain in a designated shelter or in a sturdy and
reinforced concrete building. Due to the size and slow movement
of the storm, tropical storm force winds will be slow to subside,
potentially beginning to fall below damaging levels this morning.
according to the latest forecast from the Joint Typhoon Warning
Center. Even when winds start to decrease, remain indoors until
the government of Guam gives the "all clear".
