 Patsy's erratic path near the dateline was unusual and no known tropical cyclone had taken such a path over the previous ten years, although that of Typhoon June 1958 was somewhat similar.The Japan Meteorological Agency's "best track" does not give windspeeds, only indicating that Patsy was a typhoon.The Joint Typhoon Warning Center's report disagrees on location but also has Patsy's maximum windspeed east of the dateline; the JMA's data does not indicate windspeeds.
