Definitions

Peak impact date was based upon the date of highest gust observed during the event.
Sustained refers to average (10-minute mean) land-wind speeds, stored in database as knots.
Gust refer to average (3-second mean) land-wind speeds, stored in database as knots.
MSLP refers to hourly mean sea level pressure (hPa).
Highest Individual Wave (m) was the height from trough to crest.

All land-observations were daily (00-00 UTC) from the primary (synoptic) station network.
