Integrated All Hazard forecasting, warning and response
with Tsunami Warning system
“Taking the pulse of the planet”
Evaluate Existing System
• Determine weaknesses in existing
components
• Determine GAP between existing
system and Desired system
• Write Strategic Plan to Fill GAP

Build Hydromet Network
• Design river and rainfall network
– Minimum,ideal
• Consider satellite rainfall estimates
• Radar ?
• Use all hydromet data sources
available- Seek Data partners
“Taking the pulse of the planet”
Establishing a Flash Flood System
 Select/Implement Hydrologic Modeling
System
Acquire historical
hydrometeorological data
Acquire GIS/Link to modeling
system for calibration
Modeling system must be flexible
to data availability

Develop USER Partnerships
• User Requirements for Data are your
requirements
• Develop USER partnerships
• USERS assist NMHS in developing plan
• USERS lobby government to execute
plan
“Taking the pulse of the planet”
It’s Hydrometeorology- Cooperate
Couple Meteorological Model To Hydrologic Modeling
System - QPF extremely Important
Coordination between Meteorologist and Hydrologist
imperative to provide sufficient
“Taking the pulse of the planet”
Establishing a Flash Flood System
 Forecasts Tailored to Users
 Use visualization products to communicate
impact
 Disseminate Forecasts & Data to Users
 Use mass media
 RANET, EMWIN
 Apply Operations Concept
 Develop Capacity and Sustainability

Capacity Building
• Training
– Hydrology
– Meteorology
– Computer System Administration
• Cooperative Training/On-the-Job training
– Models,Data Systems,communications
– Automated Flood Warning Systems
• Other
– Workshops Seminars
– University Training
“Taking the pulse of the planet”
SUMMARY
• Develop Strategic VISION i.e. a plan
• Develop Partnerships with USERS
– (energy. Emergency services,media,transportation
• Costs vs Benefits calculated for network
enhancement
• Make sure maintenance plans and funds
included to assure sustainability
• Sell plan at every opportunity
• Have patience
