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.
