Flooding in the Ozarks
Mission The National Weather Service provides
weather, water, and climate forecasts and
warnings for the United States, its territories,
adjacent waters, and ocean areas for the
protection of life and property and the
enhancement of the national economy. And NWS
data and products form a national information
data base and infrastructure which can be used by
other government agencies, the private sector,
and the global community.

Flooding in the Ozarks

• NWS SGF issues forecasts warnings for 37
  counties in SE KS and SW MO.

Flooding in the Ozarks

• Flash flooding is the 1 weather killer in the
  Ozarks
• The threat is compounded by hundreds of low water
  crossings.

FFRAP Goals

• Development of GIS enhanced Flash Flood Analysis
• Identify flood behavior factors
• Categorize flood risk rating per basins, streams,
  communities, etc.
• Develop GIS utilities that integrate this data
  into the warning process.

17
FFRAP Goals

• Provide emergency management w/ data to assess
  local flood threats
• Create GIS enhanced flash flood warnings for the
  general public
• Detailed flood risk information for specific
  basins, streams, or communities.

The Future

• Development of Flash Flood Risk Analysis
• Create additional analysis maps using GIS
• Intertwine risk analysis data into a risk rating
  system
• Analyze edit existing small basins
• Create interactive map or GUI for warning
  operations
• Develop GIS enhanced flash flood guidance for
  individual flood basins

40
The Future

• Development of GIS Flash Flood Warnings
• Warning text integrates specific flood points
  based on risk rating
• Warning polygon and graphics displayed on the web
  
• Dynamically display population, infrastructure,
  streams, and low water crossings at risk
• Create interactive web GUI for users

The Future

• Work with Our Partners to Develop
• Safety campaigns
• Mitigation strategies
• Flood detection and sensors
• Enhance flood response and recovery
