5. NOAC Yokosuka Tropical Cyclone Watch Officer (CDO)
“Watches” anytime a TC is forecast to come within 180NM of a CNFJ asset
Maintains a continuous TC plot, compares to other fixes
Analyzes all available local data
Satellite Imagery (Center fixes, Scatterometry,
Rain rate, winds, structure)
Outside Agencies (JMA, KMA, Hong Kong
Observatory, NWS/NOAA, ECMWF, UK)
Model Data (Synoptic scale and Mesoscale)
Nomograms / Wind Probability
Local knowledge
Prepare and deliver staff briefs
Issues local warnings

6. Tropical Cyclone Watch Officer
Tropical Cyclone Watch Officer is now a part of the CDO qualification. It became a requirement after TC 26W of 2004.
During Typhoon 26W (Ma-On) in October 2004, allision involving USS VINCENNES and USS CORONADO occurred when USS VINCENNES snapped mooring lines and was blown from its Harbor Master Berth.

12. Questions and Concerns
Warning #42 gave indications storm was weakening
Warning #43 jumped from 50kts to 70kts
What was the wind Radii depicting?
What did the wind probability product look like?

13. Facts of Life NOAC has a small staff with many deployed
C7F sets sortie conditions
NOAC main focus is ASW
Resource protection is NOAC’s “side job”
Timing is very important for morning Typhoon Battle Rhythm in order to support CNFJ morning brief.
NOAC needs to assess
Conference call
Prep brief
People in Japan get very concerned when JTWC says one thing but when they go to JMA’s webpage, they get confused/tense when there is a difference and it leaves NOAC in the uncomfortable position of trying to explain the delta.

14. Final Thoughts C7F and CNFJ are generally “Happy” We appreciate:
Early communications when major changes are expected.
Early Warnings- warn on priority systems first (ie. Storm tracking to make land fall on Japan before one that will make land fall on China)
Not dropping warnings when storm goes extratropical until after passes naval facilities
We need better understanding:
Wind Probabilities products, How to apply to TCCOR Recommendations
Wind Radii Depictions for systems undergoing extra tropical transition
Anticipated rain amounts (minor flooding in housing)
Potential for significant storm surge
