  1. Thoughts From WFO San Angelo Jonathan Brazzell San Angelo TX

  2. WDM Technology • What we currently have works well. • Wind events from broken lines and brief tornadoes remain the biggest challenges.

  3. Wind Farms • We are a little concerned about the wind farms that are going in very close to the radar sites. • Few problems thus far. • They are growing rapidly, so we may see future problems. • Beam blockage? • Velocity problems? • Problems with radar algorithms?

  4. WES Training • Current setup helps forecasters to interpret radar information and work on polygon placement. • Lacks the configuration that the whole team can practice on. Developing listening skills while interpreting radar data in a warning environment is important to putting it all together. • Should be easier to play back saved off data for post event analysis and verification.

  5. Polygon/LSR Plotting • Polygon puts more pressure on storm report location. • Need to be more specific in location. Entering LAT/LON helps. Where is 19 miles west of Ozona? • Should LSR’s go out to more than two decimal places? (± 0.6nm) • Spotters, chasers and others in the public are more equipped with GPS technology. • What if we could click on a radar image and enter a report. This may help to cut down on the poorly placed reports in the heat of battle.

  6. Polygon/LSR Plotting Spotter report: 19 miles Northwest of Ozona Spotter report: 12 miles Southeast of Segovia

  7. Grid Based Guidance • The grid based MEHS should be a big help. We have been evaluating this using GR2AE and has shown encouraging results compared to the HDA. • Should help to reduce polygon/FAR area. • The more grid based guidance the better.

  8. Communication to the User • Warning process should begin well before actual warnings are issued. • Strive to come up with better methods of communicating information. • Must be easy for the user to understand. • Communicate the level of uncertainty. • How extreme an event may be. • Expected impacts.

  9. How do we present information to decision-makers? • Text? • Telephone? • Graphics? • Video?

  10. WFO San Angelo’sMultimedia Briefing • Prepared at least once a day and more often if there is an approaching event. • Graphics prepared in FSL’s FXC software in AWIPS and other sources. • Graphics imported into a Powerpoint presentation • Audio recorded within Powerpoint • Briefing produced within Camtasia software • Briefing uploaded to web

  11. Multimedia Goals • Looking to reduce the number of steps involved and better compression techniques. • While keeping compliant with internet policy.
