3. 3 Objective Implement the Valid Time Event Code in NWS Watch, Warning and Advisory productsImplement the Valid Time Event Code in NWS Watch, Warning and Advisory products Improve interpretation and accessibility of critical NWS productsImprove interpretation and accessibility of critical NWS products Reduce errors in critical NWS productsReduce errors in critical NWS products Improve end-to-end tracking of products associated with specific meteorological and hydrological eventsImprove end-to-end tracking of products associated with specific meteorological and hydrological events

4. 4 Background VTEC “implemented” in AWIPS OB2 softwareVTEC “implemented” in AWIPS OB2 software VTEC was scheduled to be turned on 2 December 2003 for some locally generated watches and warningsVTEC was scheduled to be turned on 2 December 2003 for some locally generated watches and warnings Partner’s conference call held 27 August to discuss status of 2 December implementationPartner’s conference call held 27 August to discuss status of 2 December implementation Consensus to slip VTEC implementationConsensus to slip VTEC implementation Consensus to slip implementation confirmed at 11 September Partner’s meetingConsensus to slip implementation confirmed at 11 September Partner’s meeting

5. 5 Current Status VTEC specification updated to address shortcomings identified during Watch-by- County and internal testingVTEC specification updated to address shortcomings identified during Watch-by- County and internal testing Revised specification in internal reviewRevised specification in internal review Partner’s VTEC working group integral part of specification revisionPartner’s VTEC working group integral part of specification revision Software developers tasked to implement revised specificationSoftware developers tasked to implement revised specification Some development risk if changes to specification occur during review cycleSome development risk if changes to specification occur during review cycle
