Multiple flooding sources threaten Honolulu's infrastructure. Researchers found in the next few decades, sea level rise will likely cause large and increasing percentages of land area to be impacted simultaneously by the three flood mechanisms. Further, they found direct marine inundation represents the least extensive -- only three percent of the predicted flooding, while groundwater inundation represents the most extensive flood source.

I mean, considering Hawaii is surrounded by ocean they will experience consistent flooding. Not only that but with the global warming issue in other areas increasing that will also put islands like Hawaii at great risk. There should be something to eventually evacuate those people over the decades because sea levels won't be the same as it once existed again.
