NOUS41 KWBC 091250 PNSWSH Public Information Statement National Weather Service Headquarters Washington DC 850 AM EDT Tue Aug 9 2011 To: Subscribers: -Family of Services -NOAA Weather Wire Service -Emergency Managers Weather Information Network -NOAAPORT Other NWS Partners and NWS Employees From: Therese Z. Pierce Marine and Coastal Services Branch Chief Subject: Soliciting comments for Experimental Probabilistic Tropical Cyclone Inundation Guidance Products through November 30, 2011 Effective September 15, 2011 and continuing through November 30, 2011, the NWS is seeking user feedback on Experimental Probabilistic Tropical Cyclone Inundation Guidance Products. The Experimental Tropical Cyclone Inundation Guidance products consist of two suites of probabilities for the Gulf of Mexico and Atlantic coastal area: 1. Probabilities, in percent, of inundation exceeding 0 through 20 feet above ground level, at 1 foot intervals, e.g., the probabilities in percent of inundation exceeding 0 feet, 1 feet, 2 feet, 3 feet ... 20 feet. 2. Probabilities of inundation heights, above ground level, being exceeded. The suite of products range from 10 to 90 percent at 10 percent intervals. The probabilistic inundation products do not account for tide, waves and fresh water, i.e., precipitation runoff and river inflow. The products are based upon an ensemble of Sea, Lake, and Overland Surge from Hurricanes (SLOSH) model runs using the National Hurricane Center(NHC)official advisory. These products account for track, size, and intensity errors based on historical errors. The probabilistic inundation products will only be generated when hurricane watches and/or warnings are in effect for the Atlantic and Gulf Coasts of the continental United States. When produced, graphical versions of the products will be posted online at: http://www.weather.gov/mdl/phish ESRI shape files and GRIB2 files will be also be available for download from the above Website. Users are encouraged to provide feedback on these experimental products by using the brief survey and comment form online at: http://www.weather.gov/survey/nws-survey.php?code=phss Planning is underway to provide the Probabilistic Tropical Cyclone Inundation Guidance Products in GRIB2 format via the NWS Telecommunication Gateway in the future.
