Proposed Changes to MWW Preparation for 2015 Tropical Changes MWW product to carry Tropical Wind Watches & Warnings for marine zones Tropical Storm Watch and Warning (TS.A, TS.W) Hurricane Watch and Warning (HU.A, HU.W) New WFO TCV carry Tropical Wind Watches & Warnings for land zones

Storm Surge Improvements NOAA Storm Surge Roadmap commenced in 2005, following Hurricane Isabel (2003) and was energized by Hurricanes Katrina (2005), Ike (2008) and Sandy (2012) Comprehensive social science research has been completed and documents the public s understanding, or lack thereof, of storm surge NWS needs to provide (text) storm surge information in terms of total water level/inundation (height above ground) NWS needs to provide a forecast inundation graphic World Meteorological Organization (WMO) and Hurricane Sandy Assessment recommend a storm surge warning, a missing link for our nation s hurricane program

Storm Surge Inundation Graphic The entire graphic including colors, labels, thresholds, wording was tested extensively by social scientists with focus groups Implementation of experimental tropical cyclone inundation graphic in 2014 Lays the foundation for extra-tropical inundation graphic (beyond 2015)

Storm Surge Watch/Warning NWS is developing a collaborative process between the NHC and WFOs to issue tropical cyclone storm surge watches and warnings Implementation of experimental tropical cyclone storm surge watches and warnings in 2015 Future work: Expand to include extra-tropical storms AMS February 5, 2014

Experimental Tropical Cyclone Impact Graphics (TCIG) Graphics Provides threat and potential impact based information from tropical cyclones: - Wind - Coastal flooding - Inland flooding - Tornadoes Some offices also issue a marine hazards and combined impact graphic Working with social scientists on how to more effectively communicate the impacts Mosaic of multiple WFOs Operational in 2015 http://w1.weather.gov/tcig AMS February 5, 2014

http://weather.gov/tcig Official implementation planned for the 2015 season DS/PS/SW

New Interactive Tropical Cyclone Page Provides all tropical information from the National Centers and WFOs on one interactive web site Contains the hazard information from the new TCV and TCIG products Enables user access to all the info derived from these new products to be easily accessible through a new web interface

HLS/TCV/Storm Surge Key Milestones Date Action Status Apr 2013 Storm Surge Inundation Graphic approved by Social Scientists Complete Feb 2014 New HLS/TCV examples approved by social scientists In Progress May 2014 Develop HLS/TCV requirements On Track Jun 2014 Develop HLS/TCV formatter On Track Jun 2014 Implement experimental tropical inundation graphic On Track Jul 2014 Issue Public Information Statement (PNS) announcing experimental test of new TCV Aug - Nov 2014 OT&E of experimental TCV at Operations Proving Ground On Track On Track Jun 2015 Implement experimental tropical Storm Surge Watch & Warning On Track Jun 2015 Implement operational WFO TCV & updated HLS On Track Jun 2015 Implement operational TCIG approved by social scientists On Track Jun 2016 Implement interactive tropical cyclone web portal On Track Jun 2016 Implement operational tropical Storm Surge Watch/Warning and inundation graphic On Track
