  1. MDL’s ExtratropicalStorm Surge An Introduction Anne Kramer Scientific Programmer NOAA/NWS/OST/MDL & TCA

  2. ETSS background • ETSS model is based on SLOSH, but modified to use GFS winds on 1° grid • Runs 4x daily in NCEP operations • Basins updated at MDL’s discretion; updates: • Alaska, Bering Sea: 1996 • Alaska, Arctic: 1998 • Gulf of Alaska: 2008 • East Coast: 1999, 2008 • Gulf of Mexico: 1999, 2011 • West Coast: 1998, 2011

  3. ETSS background • Resolution varies • Gulf of Mexico ~ 4km • East Coast ~ 9.4km • Alaska ~ 6.7km • West Coast ~ 6.5km • Each run has a 2 day initialization and a 4 day forecast period, for a total of 6 days • Results posted to the web • http://www.nws.noaa.gov/mdl/etsurge/ (text & hydrographs) • http://weather.noaa.gov/pub/SL.us008001/ST.expr/DF.gr2/DC.ndgd/GT.slosh/ (gridded data) • http://www.opc.ncep.noaa.gov/Loops/SURGE_GOM_EAST/SURGE_GOM_EAST_96_HR.shtml (gridded)

  4. ETSS results for 3/4/2011 OPC’s website displaying gridded ETSS results MDL’s website displaying total water level station status map, based on ETSS output

  5. Forecast Total Water Level for Hurricane Ike, Based on ETSS

  6. Forecast Total Water Level for Hurricane Ike, Based on ETSS OPC’s website displaying gridded ETSS results for 3/4/11 Station total water level plot showing forecast for Ike storm surge event at Galveston, TX

  7. MDL’s Participation in SURA Inundation Testbed Effort • Completed • Uploaded to SURA server: • archived forecast graphs and text files for north East Coast stations for the 3 periods of interest • Projected • Reproduce gridded forecasts using archived GFS wind data • Potentially create gridded hindcasts using reanalysis GDAS winds
