1998 Sydney Hobart Yacht Race Weather Conditions (and Chronology of Events) Notes Location of events are based on information supplied by NSW Water Police including the CYCA’s “Chronology of Events” and the AUSSAR Search and Rescue Review Times are in EST (+ daylight savings) All distances are in nautical miles Surface pressure, wind and wave depictions are provided by the Bureau of Meteorology. The Bureau accepts no responsibility for any subsequent manipulations and alterations to these data files.

Explanatory Notes Wave Heights in metres wave height increase by colours changing from blue (lowest) - red - yellow (highest) white vectors represent direction of waves Wind Barbs beginning of the barb represents the location that the winds has been calculated the direction of the barb represent the direction of the wind the feathers of the barb represent the strength
