Advanced Hydrologic Prediction Service Overhaul of NWS Hydrologic Services
Mississippi Flood of 1993, Red River of the North Flood of 1997
Service and Science Enhancements River Forecast Services
Longer-range ensemble forecast technique to quantify forecast certainty Projected completion in 2014 (2553 of 4011 forecast points as of 04/2010)
Flash Flood Services Higher resolution modeling for fast responding rivers Advanced tools to better identify risk and improve warning accuracy and lead time
Inundation Mapping Services Depict spatial extent and depth of flood waters near NWS forecast points 47 points as of (04/2010) Partnerships with FEMA, USGS, States, River Authorities, etc.
Dissemination Services http://water.weather.gov
Outreach Biannual survey of key customers administered by CFI Group
CSI for 2008 – 80 ( Government average – 68) National Flood Safety Awareness Week (launched 2005) Partnership with The Weather Channel® to develop educational videos

Probabilistic Forecasts
90 day Exceedance Probability Weekly Exceedance Histogram
http://water.weather.govNWS Hydrologic Services
90 Day Exceedance Example
Conditional stages higher than “observed” stages…therefore
wetter than normal
http://water.weather.govNWS Hydrologic Services
Weekly Histogram Example
12 out of 50 times the stage increased above the simulation starting stage (25%)
38 out of 50 times the stage decreased from the starting stage and the starting stage was always the maximum
At 12z 9/17/2008SOLT2 was 26.26ft
75% chance of being above flood stage 3 months from now
