2. Recent Activities Operational GFE (2.5 km resolution) changed to a larger domain to encompass OFF domain during benign weather regime (8 June 2009 to 1 July 2009) Operational GFE (2.5 km resolution) changed to a larger domain to encompass OFF domain during benign weather regime (8 June 2009 to 1 July 2009) Slowdowns/GFE crashes/Workstation lockups related to hardware/software deficiencies Slowdowns/GFE crashes/Workstation lockups related to hardware/software deficiencies GFE domain reverted to original size GFE domain reverted to original size

3. Recent Activities (cont’d) After OFF test on operational GFE, workstation memory increased to 4 GB from 2 GB per PR RC After OFF test on operational GFE, workstation memory increased to 4 GB from 2 GB per PR RC Hesitancy to make changes to operational GFE due to possible database corruption/ operational implications (entire gridded database lost when initial domain change made) Hesitancy to make changes to operational GFE due to possible database corruption/ operational implications (entire gridded database lost when initial domain change made) Have begun to use IC4D workstation as test bed for gridded High Seas and Offshore forecasts Have begun to use IC4D workstation as test bed for gridded High Seas and Offshore forecasts

4. Current Status Operational GFE domain

6. Vision & Challenges Aggressively but carefully pursue a transition to gridded marine forecasts Aggressively but carefully pursue a transition to gridded marine forecasts All centers to proceed on approximately the same timetable, with respect to development, experimental grid and product production and dissemination, and operational implementation. All centers to proceed on approximately the same timetable, with respect to development, experimental grid and product production and dissemination, and operational implementation. Determine a source(s) of funding (ideally a national source) for software development, and hardware/servers to handle grid processing. Determine a source(s) of funding (ideally a national source) for software development, and hardware/servers to handle grid processing. Forecast uncertainty, especially for warning-level events, must be addressed early in this transition process, and not be an afterthought.

7. Vision & Challenges Separate GFE server for OFF/HSF domain (backup and resolution issues) Separate GFE server for OFF/HSF domain (backup and resolution issues) Prepare gridded forecasts out to day 5 at 12 hour increments (valid 00/12 UTC) to support current “legacy” products during transition period Prepare gridded forecasts out to day 5 at 12 hour increments (valid 00/12 UTC) to support current “legacy” products during transition period Initial forecast elements to include MSLP, Wind, Wind Gust, SigWvHt, Wx, Hazards as well as Highs, Lows and boundaries Initial forecast elements to include MSLP, Wind, Wind Gust, SigWvHt, Wx, Hazards as well as Highs, Lows and boundaries Additional grids to be added over time, incl. Swell & Period, WindWvHt, etc. Additional grids to be added over time, incl. Swell & Period, WindWvHt, etc.

9. Vision & Challenges Collaboration and coordination a significant challenge along borders (timing of grid production, techniques/models used, etc.) Not only center to center coordination, but also center to WFO. Collaboration and coordination a significant challenge along borders (timing of grid production, techniques/models used, etc.) Not only center to center coordination, but also center to WFO. “Ghost” area from 130E to 160E (North of EQ) is currently part of analysis area, but not “forecast” area -- Implications for WFO Guam and Micronesian island groups “Ghost” area from 130E to 160E (North of EQ) is currently part of analysis area, but not “forecast” area -- Implications for WFO Guam and Micronesian island groups
