• The greatest potential killer in a tropical cyclone
• Abnormal rise in water generated by a storm, over and above the astronomical tide
• Temporary rise in sea level that effectively moves the coastline inland
• Caused primarily by force of wind blowing across water surface
• Contribution by low pressure within center of storm is minimal

The NWS Storm Surge Program
• Total Water Level Guidance: produce water level analyses, forecasts, and observations that include all contributions to surge
• Surge, tides, waves, fresh water, background anomaly
• Inundation Products: provide information about the water depth over the land (inundation) above ground level (AGL)
• Communicating Actionable Information: provide information that people can act on
• Transition from Deterministic approaches to ensemble/probabilistic approaches

Actionable Information
• NWS has assembled teams to investigate a collaborative watch/warning CONOPs for storm surge and begin prototyping ideas for implementation– HFIP Social Science contract established to
investigate user requirements/preferences– Initial ideas tested informally during Irene– NHC/WFOs testing collaborative W/W concepts

• Represents the probable track of the center of the tropical cyclone.
• Formed by connecting circles centered on each forecast point (at 12, 24, 36 h, etc.)
• Size of the circles determined so that, say, the actual storm position at 48 h will be within the 48-h circle 67% of the time.
