Hurricanes-Inundation Overview

1. Hurricanes-InundationOverview • Objectives: • Improve forecasts of tropical cyclones and related inundation hazards to enhance mitigation decisions by emergency management officials at all levels of government and by individuals • Increase communities’ ability to assess and improve their resilience to tropical cyclones and related inundation • Benefits • Hurricane forecasts, warnings, and associated emergency responses already save the Nation $3B/year • Better preparation, response, and mitigation will reduce the average cost of storm-related disasters by $700M/year.

2. Hurricanes-InundationObjectives Achieved in Program Plan • Better forecast information for emergency management officials and individuals • Acceleration of improvements in hurricane intensity forecasts through HWRF improvements • Initial operational implementation of advanced model guidance for inland flooding in selected coastal regions • Information and tools to enable communities to improve their resilience • Coastal Community Resilience Toolkit available for communities affected by hurricanes

3. Hurricanes-InundationDesired End State Emergency managers and decision-makers will be better able to take effective measures to mitigate the impacts of tropical cyclones and related inundation. Communities will be better able to improve their resiliency to hazards associated with tropical cyclones and inundation. • FY09 • Computing resources to support hi-res models to improve intensity forecasts tripled • Enhanced field program to improve understanding of hurricane intensification • Remote buoys for early detection/verification sustained • FY13 • Rate of improvement of intensity forecast guidance doubled • Information and tools available that enable communities to improve their resilience • Dynamic storm surge model operational • Advanced hydraulic model for forecasting inland coastal flooding operational in the Carolinas • Improved scientific understanding of precipitation processes available for incorporation in models
