Hover or tap either graph to follow the track. The slider controls both graphs. Each line uses its matching colored axis.

Forward speed measures the center’s motion. ACE accumulates squared one-minute winds at 00, 06, 12 and 18 UTC during tropical or subtropical stages at 34 kt or above. Missing observations make ACE partial. Missing measurements remain gaps.

STORM HISTORY

Track and intensity summary

Rammasun is listed in the Western Pacific basin for the 2014 season. Its archived track begins on 9 Jul 2014, 06:00 UTC at 8°N, 154.3°E. US-agency wind is not available for this first observation. These dates describe the available observations, which may include stages before and after the tropical cyclone phase.

The first Category 5 observation appears on 18 Jul 2014, 06:00 UTC. The highest recorded tropical-stage one-minute sustained wind is 140 knots (161 mph / 259 km/h), first recorded on 18 Jul 2014, 06:00 UTC at 19.9°N, 111.3°E. The minimum recorded tropical-stage central pressure is 918 hPa on 18 Jul 2014, 06:00 UTC.

The full record spans 264 hours and approximately 6,060 kilometers along the recorded center positions. The last recorded position is 23.8°N, 103.3°E on 20 Jul 2014, 06:00 UTC. The final tropical-stage observation is earlier, on 20 Jul 2014, 03:00 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.
