It has its own page because it reached category 4 or stronger.
This page gives the official record's figures. It does not describe the human cost of the storm, which is far larger than any wind speed or pressure here.
Where it came ashore
The record shows no landfall: the storm stayed at sea.
How to read this track
The line joins the storm's six-hourly positions with straight lines, coloured by its intensity at each point, so it shows how the storm strengthened and weakened. The real path curved between the positions. A dashed grey stretch means the storm had become post-tropical. Records before the satellite era (about the 1960s) are estimates.
