  • Storm Events reports are not a complete loss inventory and reporting practices vary over time.
  • Forecast-zone and marine-zone records are excluded because they cannot be assigned exactly to one county.
  • 15 optional archive damage cells contained only a K/M/B suffix, so their dollar amounts remain unknown/null rather than inferred.
  • 2 archive record with an unrecognized CZ_TYPE was excluded rather than attributed to a county.
  • The current-year file is preliminary through the latest event present in its selected official revision.
