Hawaii Storm Atlas

logo


This series of pages will allow you to see the maximum water levels and wave heights for a set of tropical cyclones coming near to, or landfalling at, Oahu and Kauai.

This Storm Atlas gives a way to navigate through hundreds of pre-computed hurricane scenarios near the Hawaiian Islands of Oahu and Kauai. Maximum wave heights and water levels were computed using the SWAN+ADCIRC suite of models over very high resolution grids encompassing all of the Hawaiian Islands and much of the North Pacific Ocean. The wave heights presented here are the Significant Wave Height (Hs), which is the standard representation for waves given in marine forecasts, for example. The water levels presented here are the maximum storm surge elevations. These water levels do not include wave runup, where individual waves or groups of waves may penetrate further than the slowly varying water level computed by ADCIRC. Because of this, coastal areas exposed to significant wave action can see wave runup further inland than shown here.

The map below shows the Hawaiian Islands and numbered storm tracks heading directly North. To see other tracks with different landfall angles, use the pull-down menu to select the landfall location (where the storm crosses 21.3 degrees north for Landfall locations L0-L14 or 20.0 degrees north for Landfall Locations B1-B13). To go to a page where you may see waves and water levels from a large variety of these storms with this landfall location, select the "go" button.
