2016 Hurricane Matthew

Estimated storm surge and significant wave heights caused by the hurricane, focusing on the timing of its landfall on Haiti

Summary: Although storm surge produced by the Hurricane Matthew was not too significant compared to some of the recent historical events such as the 2013 Typhoon Haiyan in the Philippines, extremely large waves, estimated 10 meters or larger in just offshore of Haiti's south- western coast, extensively battered vulnerable coastal communities.

Note: The present tropical cyclone analysis was tentatively performed by referencing the NOAA Hurricane Matthew forecast/advisory
