Definitions

Sustained wind speeds (average (10-minute mean) land-wind speeds) are shaded according to the Beaufort land-wind scale Near Gale Gale Stong Gale Storm Violent Storm Hurricane .
Peak impact date was based upon the date of highest gust observed during the event.
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 are daily (00-00 UTC) from the primary (synoptic) national meteorological station network.
