At the time of this writing, Hawaii is under a Tsunami Warning.
See tsunami.gov for more information.

For the next several days, Hawaii will be located in between a
surface high pressure system to the north and several tropical
systems -- Hurricane Iona, Tropical Storm Keli, and another
tropical disturbance being monitored for development -- all
passing south of the state. This pattern will tighten the pressure
gradient and yield breezy to locally strong easterly trades.
Moisture should be limited for only a few passing showers
particularly in windward/mauka areas. Winds may ease a bit to more
moderate to breezy levels early next week, but other than that
there does not appear to be much change to the pattern in the next
several days. By the middle of next week though, will continue to
monitor potential for any lingering remnant energy from another
tropical system to approach Hawaii from the east, which could
increase moisture.
