How to read the lines. Each line is the track of one storm, drawn through its six-hourly positions and coloured by its intensity at each point (the Saffir-Simpson scale), so a line changes colour as the storm strengthens or weakens. Tap a line for its details, or tap anywhere else to see which storms have passed nearby. Weaker storms appear as you zoom in. Hurricanes, typhoons and cyclones are the same kind of storm with different names in different oceans.

What the record says

Irma was a typhoon in the Western North Pacific basin that lasted about 15 days, from 20 November 1989 to 5 December 1989. Its peak was Category 5 (140 kt) on 30 November 1989, with a 1-minute sustained wind of 140 kt (161 mph, 259 km/h). Its lowest recorded pressure was 925 hPa.

  • 15 dayslifetime

Source of the peak wind: US Joint Typhoon Warning Center (western Pacific). The regional forecast centre (RSMC Tokyo (Japan Meteorological Agency)) gave a peak of 95 kt on its own averaging convention (10-minute winds), so the two figures differ.

It has its own page because it reached category 5 or stronger.

This page gives the official record's figures. It does not describe the human cost of the storm, which is far larger than any wind speed or pressure here.

Where it came ashore

The record shows no landfall: the storm stayed at sea.

How to read this track

The line joins the storm's six-hourly positions with straight lines, coloured by its intensity at each point, so it shows how the storm strengthened and weakened. The real path curved between the positions. A dashed grey stretch means the storm had become post-tropical. Records before the satellite era (about the 1960s) are estimates.
