                      Vision / Benefits

                                      Vision
                   Eliminate weather-related wildland fire
                         death/injury
                   Reduce fire management costs and health
                         impacts, with more timely and accurate
                         forecasts


Increasing lead times for Red Flag / critical fire weather helps
  firefighting and emergency response
     • Tactical efficiency improvements: Each 1% reduction in
       average time of Type-I deployments saves ~ $10 M
     • Strategic efficiency improvements: Reducing escaped fires
       by 1 each year saves ~ $12.5 M

                      Outstanding R&D Needs
• Improve high-resolution prediction methods for complex terrain
• Develop methods for verifying spot forecasts, given flexible, variable
  observational data
• Improve methods to ingest incident-specific observations into high-
  resolution forecast models and guidance
• Improve understanding of convection as related to critical fire weather
• Develop methods for forecasting, verifying dry thunderstorms
• Improve methods to forecast smoke impacts
