STORM HISTORY
Track and intensity summary
Arthur is listed in the North Atlantic basin for the 2026 season. Its archived track begins on 15 Jun 2026, 00:00 UTC at 23.5°N, 100.3°W. The first observation lists sustained winds of 15 knots. These dates describe the available observations, which may include stages before and after the tropical cyclone phase.
The highest recorded tropical-stage one-minute sustained wind is 40 knots (46 mph / 74 km/h), first recorded on 17 Jun 2026, 18:00 UTC at 28.9°N, 95.8°W. The minimum recorded tropical-stage central pressure is 999 hPa on 18 Jun 2026, 00:00 UTC.
The full record spans 72 hours and approximately 980 kilometers along the recorded center positions. The last recorded position is 29.4°N, 94.8°W on 18 Jun 2026, 00:00 UTC.
This summary is calculated from the NOAA IBTrACS archive and the NHC operational best track. The peak category, tropical storm, 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, with provisional positions from the NHC operational best track; post-season analysis revises them. Wind and category use US-agency records; minimum pressure is calculated during the tropical stage, with the archive’s pressure source retained. Categories refer 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.
