1. Company Confidential/Proprietary A Regional Prototype System for a National Problem Chesapeake Inundation Prediction System Bridging the Gap from Forecast to Impact Presented to: MARACOOS Annual Meeting 15 December 2011

2. What Emergency Managers Get Now Current Text Storm Surge Forecast

3. What Emergency Managers Want Where will it flood? When will it flood? How deep will it be? How long will it last? What is the uncertainty in the forecast? Forecast Impact

4. From Forecast … To Impact MATURING TECHNOLOGY Regional scale atmospheric wind forecast model Very high-resolution hydrodynamic models with land flooding Very high-resolution land elevation data (LIDAR) Emerging GIS and visualization capabilities for integrated, high- resolution pictures and products Bridging the Gap
