Typhoon Warning issued April 16 at 8:17PM ChST by NWS Tiyan GU

Recommendations

People should remain in a designated shelter or in a sturdy and
reinforced concrete building to ride out the storm as tropical storm
force winds are occurring at Rota, Tinian, and Saipan. Due to the
size of the storm, the latest forecast has tropical storm force
winds continuing over northern Rota waters over the next few hours
tonight, and through the very early morning hours Friday for
Tinian and Saipan. Even when winds start to decrease, remain
indoors until the "all clear" is given. Strong to tropical storm
force gusts remain a possibility for the next day or two,
especially with any passing shower.

Damage to remaining metal roof homes remains possible.
Electricity and water will remain unavailable for days and perhaps
weeks after the storm passes. Most trees will be snapped or
uprooted. Fallen trees may cut off residential areas for days to
weeks.

Stay indoors during heavy rain and windy conditions associated with
Typhoon Sinlaku (04W). The window of time to complete preparations
for the protection of life and property has closed. Find shelter to
ride out the storm. Remain in a sturdy shelter until the "all clear"
is given. Heed the advice of your local emergency managers and
officials, and continue to monitor forecasts by your local National
Weather Service office in Tiyan, Guam.
