   A tsunami warning indicates that a tsunami may be imminent and that coastal locations in the warned area should prepare for flooding.
   The initial warning is typically based solely on seismic information.
   After the tsunami is recorded on sea level gages, the warning will be cancelled, restricted, expanded, or downgraded to an advisory.
   Warnings indicate that flooding up to the maximum expected limit is possible and residents should follow their local emergency management instructions.
   Warnings are issued when the earthquake information or tsunami forecasts indicate that a wave over 1 meter in amplitude is possible.
