Post-tropical and extratropical passes

A further 2 systems passed within 50 miles after losing tropical characteristics. These are excluded from the counts above because they were no longer tropical cyclones at their closest approach — but several were highly damaging, so they are listed here.

About this data. Computed from NOAA's HURDAT2 Atlantic and Northeast Pacific hurricane databases (hurdat2-1851-2025-02272026.txt), covering 1863–2025. Tracks are recorded every six hours and are interpolated to one-hour steps before distances are measured, so closest-approach figures are not distorted by the sampling interval. Distances are measured to the parish's Census internal point, not to its nearest boundary, so a storm listed at 55 miles may still have crossed the coastline — see Methodology. Records before about 1900 are sparser and less precise than modern ones, and storms that stayed at sea were less likely to be recorded at all.
