Based on all available data there is no longer a destructive tsunami threat to the state of Hawaii. Therefore the tsunami warning for Hawaii is cancelled.
However some coastal areas in Hawaii may continue to experience small sea level changes and strong or unusual currents lasting for several more hours.
This tsunami warning cancellation does not mean it is now safe to resume normal activities or reenter evacuated shoreline areas. Your county civil defense agency and police department will make this determination. Stay tuned to your local broadcast station for the civil defense -all clear- announcement for your area.
Repeat – do not reenter evacuated shoreline areas until announced by your county civil defense agency. Stay tuned to your local broadcast station for the -all clear- announcement for your area. Please yield to roadblocks and uniformed officers who are controlling reentry into evacuated shoreline areas.
This will be the final message issued for this event unless additional data are received.
