1 Gulf Coast Hurricane Preparedness Conference NOAA TOOLS FOR HURRICANE EVACUATION Todd Davison, NOAA Gulf Coast Services Center November 12, 2008 Mobile, AL

2 Role of CSC Customer Focused Technology Experts Where were required to be Acting as the Middle-man Must know the customer as well as the technology (have to straddle the fence) Effectively buying down the cost for coastal information and tools

3 Customers: State and Local Coastal Resource Managers Emergency managers Floodplain managers Protected areas Coastal planners Regulatory agencies Fish and wildlife agencies Estuarine reserves Sea Grant programs Educators NOAA Coastal Services Center Coastal Hazards Theme: Provide emergency/floodplain managers with GIS-based coastal hazard tools and spatial data that will assist them in mitigating against, responding to, and recovering from the impacts of coastal hazards

5 Hazards Toolkit Historical Hurricane Tracks Tool Storm Information Products NWS Flood Severity Mapping Storm Surge Remapping Model Storm Surge Visualization Hurricane Evacuation Zone Maps Mapping tools and templates, Training Courses, Visualization Techniques, Methodologies and Best Practices, and Data Resources.

6 Historical Hurricane Tracks Tool

7 Storm Information Website Storm Data Resource Guide Storm Mapping Tutorial Helping you find the data and tools needed before, during, & after a storm.

8 Storm Mapping Tutorial aid emergency and coastal managers during hurricanes…. by showing how to find and use NOAA meteorological and hydrological data…. and stepping through GIS procedures to generate map products that address storm-related hazards. A series of 13 modules that can:

9 Storm Mapping Tutorial + NWS graphical forecast NHC graphical hurricane track forecast Example Application and Map Product

10 Storm Mapping Tutorial Final Product Examples Storm Track & ImageryForecast Windspeed SLOSH model dataFlash Flood Guidance

11 HURREVAC Inland Flood Planning and Response Tool HURREVAC Inland Flood Planning and Response Tool Inland Flood Tools added to HURREVAC for Coastal States from Texas to Maine, Puerto Rico and the U.S. Virgin Islands Rain / River Drop-down Menu Provides 24 hour QPF forecasts, affected area lists, and river flood outlook products River Gage Data Display River gage observations and forecasts Hydrograph at Forecast Points Observed and forecast data at NWS river forecast points includes historical crests and flood impacts Q3 and DFIRM Maps at forecasts Points 24,000 scale maps at river forecast points for 100 and 500 year flood inundation for FEMA Region IV Inland Flood Tools added to HURREVAC for Coastal States from Texas to Maine, Puerto Rico and the U.S. Virgin Islands Rain / River Drop-down Menu Provides 24 hour QPF forecasts, affected area lists, and river flood outlook products River Gage Data Display River gage observations and forecasts Hydrograph at Forecast Points Observed and forecast data at NWS river forecast points includes historical crests and flood impacts Q3 and DFIRM Maps at forecasts Points 24,000 scale maps at river forecast points for 100 and 500 year flood inundation for FEMA Region IV

12 HURREVAC Quick Reference Guide Collaboration with FEMA Region IV Provides quick reference to Government Officials on HURREVAC functionality Highlights GIS functionality and using NOAA forecast data Available on Hurricane Preparedness Website

13 HURREVAC Storm Surge Module Available through tide gages Features - Exercise mode - SLOSH forecast mode - 20% error margin - Gage marked with S when real time data available

14 Flood Severity Mapping Visualize NWS flood categories Display potential flood inundation for each of the NWS categories Flood Stage and below Minor Flooding Moderate Flooding Major Flooding, including Flood of Record Graphical depiction of flood risk and impacted areas

15 Flood Severity Mapping Show inundation extent, water depth, & flood categories 16 locations in North Carolina now on website 35 locations for Gulf of Mexico region will be on website in the next year Partnering with FEMA Map Modernization program to decide which region to look at next

16 Comprehensive Hurricane Preparedness Study CHPS expands on Hurricane Evacuation Study. Chatham County, GA Pilot Remap Storm Surge Zones – GIS model Map Shallow Coastal Flooding Data Access for multiple county agencies Center will work with other states/counties to acquire, set up, and run the model.

17 GIS model uses a DEM and SLOSH model MOMs to determine surge extent for each Saffir-Simpson hurricane category (1 to 5) Model output is a shapefile representing the horizontal extent of surge for a category Remapped surge zones redefine evacuation zones recalculate clearance times more efficient evacuations and planning Mapping Storm Surge Zones

20 Project Objectives: Assess needs of management community Assemble needed data Test a prototype storm surge model (hindcast Ivan) Improve inundation mapping Develop mapping and educational products Improving Inundation Mapping and Tools – A Gulf Coast Pilot Pilot Project Area Hurricane Ivan Impact Area ADCIRC model

21 Digital Elevation Model Mapping inundation starts with base DEM Quality of output highly dependent on quality of DEM Created from bare earth lidar Integrated bathymetry from model mesh to create a seamless topobathy surface Downloaded from LDART Flew lidar for Walton, Escambia, and Santa Rosa Counties maps.csc.noaa.gov/TCM/

22 2D – Maximum Depth

23 3D – Maximum Elevation

24 Hurricane Evacuation Zones Tool Purpose Provide a template for emergency managers to easily supply the public with evacuation zone information Template Demonstrated on the Center website as an example application for a fictitious community Access Template (code) and set-up documentation available upon request to federal, state, and local officials

25 Sample addresses Default code is parcel search (option for geo- coded streets) Application: Address Search Page

26 Simple mapping interface Evacuation zone display is specific to searched address Option to view all evacuation zone definitions Application: Map Display

27 Hazards Toolkit: Hurricane Related Resources Historical Hurricane Tracks Tool hurricanes.csc.noaa.gov/hurricanes Storm Information Products NWS Flood Severity Mapping Storm Surge Remapping Model Hurricane Evacuation Zone Maps Tool/Template Storm Surge Visualization
