• 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.
