The links below provide hurricane storm surge inundation maps
for the U.S. Atlantic coast, Oahu, the Bahama Islands, Puerto
Rico, and the Virgin Islands. They were generated using the
primary computer model used by the National Hurricane Center
(NHC) to forecast storm surge--the Sea, Lake, and Overland Surge
from Hurricanes (SLOSH) model. The accuracy of the SLOSH model
is advertised as plus or minus 20%. There are two sets of images
available. The first set, titled "Maximum Water Depth", shows
the water depth at each grid cell of the SLOSH domain. Thus, if
you are inland at an elevation of ten feet above mean sea level,
and the combined storm surge and tide (the "storm tide") is
fifteen feet at your location, the water depth image will show
five feet of inundation. The second set of images, titled
"Maximum Storm Tide", shows how high above mean sea level the
sum of the storm surge plus the tide reaches. Over the ocean,
the storm tide and water depth images will show the same values.
