STORM HISTORY
Track and intensity summary
Edith is listed in the North Atlantic basin for the 1971 season. Its archived track begins on 5 Sept 1971, 18:00 UTC at 11.4°N, 58°W. The first observation lists sustained winds of 25 knots. These dates describe the available observations, which may include stages before and after the tropical cyclone phase.
The first Category 5 observation appears on 9 Sept 1971, 18:00 UTC. The highest recorded tropical-stage one-minute sustained wind is 140 knots (161 mph / 259 km/h), first recorded on 9 Sept 1971, 18:00 UTC at 14.8°N, 83.2°W. The minimum recorded tropical-stage central pressure is 943 hPa on 9 Sept 1971, 18:00 UTC.
The full record spans 300 hours and approximately 6,400 kilometers along the recorded center positions. The last recorded position is 34°N, 84.7°W on 18 Sept 1971, 06:00 UTC.
This summary is calculated from the NOAA IBTrACS archive. Category 5 describes the storm’s peak recorded wind intensity, not its intensity at landfall or the severity of impacts at any location. Landfall times, damage and casualties have not been independently reviewed for this page.
METHODOLOGY
Data sources and limitations
The map and summary are generated from NOAA’s IBTrACS v04r01 archive. Wind and category use US-agency records; minimum pressure is calculated during the tropical stage, with the archive’s pressure source retained. Category 5 refers to the Saffir–Simpson one-minute wind scale; local agencies may use different classifications. Coastlines use Natural Earth’s 1:10m land data.
Track distance adds great-circle distances between consecutive observations, excluding gaps over 12 hours. This track has no gaps over 12 hours. The line shows the storm’s center, not its size, rainfall or flood extent. Converted wind speeds are rounded to the nearest whole unit.
