Presentation Goal

Tropical Cyclone Impact Graphics (TCIG)

  • This presentation intends to do one thing:

    • To support the recommendation for initiating and executing the necessary steps to transition the TCIG from experimental status to operational status for the 2014 season;

      • With an acceptable alternative being the 2015 season.

    • The associated Action Item is notably a “linchpin” for several other items and proposals as submitted to this year’s agenda;

      • A testament of realized value.

    • After 10+ years of development, and 6+ years of multi-regional/multi-WFO experimental provision, many feel that it is time to make an “across the board” commitment to take deliberate action.


What Does This All Mean?

Tropical Cyclone Impact Graphics (TCIG)

  • A decision to transition the TCIG to operational status will:

    • Green light the technical and developmental resources that have been waiting for the definitive “GO” signal.

  • A decision to transition the TCIG to operational status must:

    • Be accompanied by a comprehensive commitment by the agency, by the respective regions, and by each coastal WFO.

So far, we have been voting on a year to year basis whether to remain experimental; that is, whether to continue or discontinue.


Coming Off The Back Burner

Tropical Cyclone Impact Graphics (TCIG)

  • We have been waiting for the AWIPS II era.

    • Current testing at WFO Houston

  • We have been acquiring WFO feedback.

    • A diversity of WFO locations and situations; NOAA Hurricane Conferences; ERMETs (Pilot Project sites)

  • We have been listening to our customers.

    • Through direct feedback, Social Scientists, and Service Assessments

  • We are consistent in direction with proposed decision support services and Weather-Ready Nation concepts.

    • Local; Regional; National

WFO Key West, FL


Moving To The Front Burner

Tropical Cyclone Impact Graphics (TCIG)

  • Finalize baseline version 1.0 for release

    • Fully supported by agency

      • Program support, policy and directive, technical support, training support, etc.

  • Generally “freeze” experimental version

    • Implement minor enhancements as we go along, but major enhancements reserved for time of official release date.

Action Item (12-21)

Tropical Cyclone Impact Graphics (TCIG)

  • List of Action Items which have contingencies upon:

    • Item 10-39 … explore elimination of text HLS in lieu of TCIG

    • Item 12-22 … standardize availability of TCIG on WFO homepages

    • Item 12-23 … reconsider use of “low” as an impact descriptor

    • Item 12-24 … ensure timely auto-refresh of TCIG web pages

    • Item 12-25 … mature logic for inland flooding; include river flooding

    • Item 12-26 … mosaic capability; inter-site coordination; inland WFOs

    • Item 11-34 … baseline inputs; ensure harmony with NHC, HPC, & SPC

    • Item 11-35 … provide TCIG service backup capability


For Example: Decision Support Services(for local, regional, and national depictions)




TC Warnings dropped;

TCIG impact info lost

Decision Support

Tropical Cyclone Impact Graphics (TCIG)

  • Graphicasts or Impact Graphics ???

    • Local Impact Information ???

    • Objective Information ???

    • GIS Intelligent Information ???

    • Decision-making Information ???

      • Not just “Awareness” information ???

  • The Public Deserves Briefings Too

    • WFO Home Page Link

    • Recorded Briefings

    • Point-n-Click Briefings (web interface)

  • EM Briefings

    • Multi-level

TCIG !!!


Usefulness of Gridded Data

Tropical Cyclone Impact Graphics (TCIG)

  • Value of Potential Impact Grids

    • Computed GFE grid sets can be used by the HLS Formatter and other DSS formatters.

      • For example, see Item 12-17.

    • Availability to NDFD

      • Customer-derived applications

      • Time Component (THREAT vs. IMPACT)

        • Onset of impact (Ok)

        • Duration of impact (No)

          • Threat - based on “conditions”

    • Bulleted / Tabular impact information

      • For example, see Item 11-23.

    • GIS Interfaces


What Do We Need To Do?

Tropical Cyclone Impact Graphics (TCIG)

  • Finalize the layout and design of the operating versions of hazard tools.

    • Perhaps a “Tool of Tools - Dashboard” (???)

  • Mature the inland flood tool to use probabilistic QPF from HPC, and to better account for longer duration flood events (e.g., RFC/river flooding).

  • Finalize web page functionality and address the timeliness of updates.

  • Harmonize all threat definitions and impact descriptions; establish consistency thresholds among WFOs and Regions.

    • This is paramount for regional and national partners and customers such as FEMA to mosaic depictions (as accomplished via the NDFD and/or the GIS mosaicking of available KMLs).

High Wind Tool (GFE)


What Do We Need To Do?

Tropical Cyclone Impact Graphics (TCIG)

  • Establish WFO home page policy for TCIG.

  • Integrate TCIG with other hurricane decision support products/ services. Consider a TC DSS site that integrates TCIG and the Interactive Text Reader with other DSS information.

  • Enable service back-up capability with secondary and tertiary WFOs.

  • Develop and provide training updates.

  • Establish supporting policies/directives.

  • Open a pathway for adding a temporal component for impact arrival. User feedback indicates a strong desire.

  • Coordinate closely with other project teams for consistency, and to prevent message confusion.

    • Storm Surge WWA; Hi-Res Inundation Map

Coastal Flood

Tool (GFE)



Tropical Cyclone Impact Graphics (TCIG)

  • Agree to initiate and execute the necessary steps to make the TCIG operational for the 2014 season (or 2015 season). In January 2013, convene a meeting of the TCIG Team to outline a comprehensive transition strategy.
