STORM HISTORY

A damaging crossing as Glenda

Rammasun developed in the western Pacific and passed Guam as a depression, with wind shear limiting its early growth. It then moved westward and strengthened before reaching the Philippines. The eye passed directly over Rapu-Rapu in Albay on July 15.

More than 100,000 families evacuated as the storm approached. Port closures stranded thousands of passengers, flights were canceled and power failed in parts of Metro Manila. Laguna also suffered severe effects as the cyclone crossed southern Luzon.

A stronger cyclone after Luzon

Rammasun's strongest phase came after its Philippine passage. It intensified over the South China Sea, with archived sustained winds reaching 140 knots on July 18. The typhoon struck Hainan and brought destructive conditions to southern China and Vietnam before weakening inland. Its archived track ends on July 20.

QUICK ANSWERS

Rammasun in brief

What was Typhoon Rammasun's highest wind speed?

161 mph, the highest one-minute sustained wind in its tropical stage, recorded on Jul 18, 2014, 06:00 AM UTC.

What category was Typhoon Rammasun?

Category 5 at its peak on the Saffir–Simpson one-minute wind scale, first reaching Category 5 on Jul 18, 2014, 06:00 AM UTC. Other agencies classify storms differently.

What was Typhoon Rammasun's lowest pressure?

918 mb, the minimum central pressure recorded during its tropical stage, on Jul 18, 2014, 06:00 AM UTC.

When did Typhoon Rammasun occur?

The archived track runs from Jul 9, 2014, 06:00 AM UTC to Jul 20, 2014, 06:00 AM UTC, with the tropical stage from Jul 9, 2014, 06:00 AM UTC to Jul 20, 2014, 03:00 AM UTC.

Where did Typhoon Rammasun form?

Did Typhoon Rammasun make landfall?

The archive places its center over land at 4 recorded positions; the strongest is 144 mph on Jul 18, 2014, 12:00 PM UTC. Positions are six-hourly, so this is not a landfall chronology.

How many people died in Typhoon Rammasun?

40 deaths are recorded by Wikidata.

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.
