Short summary

This study shows that a small deviation of the tropical cyclone (TC) track in the west–east direction (less than 250 km smaller than the average radius of the TC) has a more dominant effect on the extent and distribution of TC damage than TC intensity or size. This suggests that track information should be considered more carefully in assessments of future TC risk.
