Major 2012 Activities

• SLOSH + Tides– Operationalize and Enhance– Explore Impact on Surge Products (MOM, MEOW,

etc.)

• PHISH– Implementation into NCEP operations– Incremental and Cumulative Time Ranges

• SLOSH Display Program– Gridded tide / datum module– KMZ fix

• P-surge Exceedance products on NHC web site
