List of Western Pacific severe tropical storms
A severe tropical storm is the third highest category used by the Japan Meteorological Agency (JMA) to classify tropical cyclones in the Northwest Pacific basin. The basin is limited to the north of the equator between the 100th meridian east and the 180th meridian. The category of the severe tropical storm is defined as a tropical cyclone that has 10-minute sustained wind speeds of between 48 and 63 knots (89–117 km/h; 55–73 mph). Background. The Northwest Pacific basin covers a vast area in the Pacific Ocean, located north of the equator , between 100°E and 180°E. Several weather agencies monitor this basin, however it is officially monitored by the Japan Meteorological Agency (JMA, RSMC Tokyo), who is responsible for forecasting, naming and issuing warnings for tropical cyclones. Unofficially, the Joint Typhoon Warning Center also monitors the basin, however these warnings measures 1-minute sustained wind speeds, comparing their scale to the Saffir–Simpson scale. The JMA uses a simpler scale on classifying tropical cyclones adapted by the ESCAP/WMO Typhoon Committee measuring 10-minute sustained wind speeds, ranging from a tropical depression, tropical storm, severe tropical storm and  typhoon. This article covers a list of systems developing in the Northwest Pacific basin that were classified by the JMA's category of a severe tropical storm. The category of a severe tropical storm ranges with 10-minute sustained winds of 48–63 kn (25–32 m/s; 55–72 mph; 89–117 km/h).
