force winds and Saipan and Tinian are now on the outer edge of the
destructive tropical storm winds. Typhoon Sinlaku is now moving
through the northern CNMI just west of Alamagan, Pagan, and Agrihan
As Sinlaku moves through the northern CNMI today and tonight, it is
forecast 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". TS force gusts remain
possible with any passing shower.
