Warning Principles
• LEAD TIME --A MUST !
• ACCURACY LEADS TO CREDIBILITY
• SYSTEM MUST BE RELIABLEl. 7x24
“Taking the pulse of the planet”
Steps in Building a Flash Flood Warning and Response System
• Build Automated Data Network• Establish Robust Communications system that is
sustainable• Models can be simple (FFG)• Need Dedicated Coordinator• 24 Hour Operations Center• Warnings must tell people risk and actions• Dissemination system a Must• Preparedness and Response a must• Awareness
