Deaths and damage

No source this site reads publishes a machine-readable casualty or damage figure for a storm of this era. The National Hurricane Center’s season tables begin in 1995 and carry deaths and damage only from 2005 in the Atlantic and 2020 in both basins; the US Storm Events record begins in 1996.

What this means

A best track is the record a warning agency settles on after the storm, not what it said at the time: position, maximum sustained wind and central pressure every six hours, revised against every observation that came in later. Category is the Saffir-Simpson scale, which runs from Category 1 at 64 kt to Category 5 at 137 kt and reads wind only, so it says nothing about surge or rain. Accumulated cyclone energy adds up the square of the wind through the storm's life, so it counts strength and duration together.
