Next Generation Warning Tool for High-Level Hydrologic Requirements

This tool aims to support the generation of flood watches, advisories, and near-term hydrologic outlooks. It integrates various outlooks, watches, warnings, and advisories under a single identifier and offers a flexible interface for defining threat areas. It also includes features such as automatic formatting for NOAA All-Hazards Weather Radio and the ability to accept input from hydraulic and probabilistic models, among others.

  1. High Level Hydrologic Requirements for the Next Generation Warning Tool Tim Helble Hydrologic Services Division Office of Climate, Water, and Weather Services

  2. High Level Requirements • Ease of use • Support generation of point-based flood watches and advisories • Generation of near-term hydrologic outlooks and non-routine hydrologic statements • Integration of outlook / watch / warning/ advisory / statements under single identifier • Integrated display of current and recommended outlook / watch / warning / advisory / statements NWS Hydrologic Services Managers Meeting Feb. 23, 2010

  3. High Level Requirements • Common interface for initiating generation of hydrologic outlooks, watches, warnings, advisories, and statements • Flexible interface for defining threat areas • Forecaster control over type of product to issue • Integrated generation of defined area and point-based products NWS Hydrologic Services Managers Meeting Feb. 23, 2010

  4. High Level Requirements • Recognition of point-based products as applying to river reaches • Automatic formatting of abridged text for NOAA All-Hazards Weather Radio • Use segment format and VTEC • Announce replacement of outlook / watch / warning / advisory using single segment • Support unique OCONUS requirements NWS Hydrologic Services Managers Meeting Feb. 23, 2010

  5. High Level Requirements • Integrated dam failure watch / warning capability • Integrated river flood / coastal flood capability • Flexibility in presenting impact information • Interactive modification of VTEC • Ability to accept input from hydraulic and probabilistic models NWS Hydrologic Services Managers Meeting Feb. 23, 2010

  6. High Level Requirements • Training mode capabilities • Links to supporting information provided through other media • Configuration management • Backup • Data Requirements NWS Hydrologic Services Managers Meeting Feb. 23, 2010

  7. High Level Requirements Some ideas to consider – implied in regional summaries: • Eliminate point-based flood advisories • Eliminate distinction between “areal” and “point” products • Provide more flexibility in the handling of cancellations and expirations NWS Hydrologic Services Managers Meeting Feb. 23, 2010

  8. High Level Requirements Some items to discuss: • Flood or flash flood – which is it? • Where do we go from here? • What about the future WHFS? NWS Hydrologic Services Managers Meeting Feb. 23, 2010
