2. Product Description
This is an ensemble product of maximum storm surge heights for all hurricanes
of a given category regardless of forward speed, storm trajectory, landfall
location, etc. MOMs are created internally by pooling all the MEOWs for a given
basin, separated by category and tide level (zero/high), and selecting the MEOW
with the greatest storm surge value for each basin grid cell regardless of the
forward speed, storm trajectory, or landfall location. As with the MEOW, it is
unknown (to the user) which combination of forward speed, storm trajectory, or
track generated the MOM used for particular cell. This procedure is repeated for
each storm category. In total 10 MOMs are made available for each basin - one MOM
per storm category and tide level (zero/high). MOMs represent the worst case scenario
for a given category of storm under "perfect" storm conditions. The MOMs provide
useful information aiding in hurricane evacuation planning and are also used to
develop the nation's evacuation zones. For more information on where the MOMs fall
within decision support, please see NHC's Storm Surge Product Decision Support Wedge.
