A very intense tropical cyclone is the highest category on the South-West Indian Ocean Tropical Cyclone scale, and has winds of over 115 knots (213 km/h; 132 mph). [24] [25] At the tenth RA I tropical cyclone committee held during 1991, it was recommended that the intensity classifications be changed ahead of the 1993–94 tropical cyclone season.
A tropical storm is a tropical cyclone that reaches maximum sustained winds between 34–63 knots (39–72 mph; 63–117 km/h). The Japan Meteorological Agency (JMA) is the main weather forecasting agency in the Northwest Pacific basin , where it measures sustained winds by averaging wind speeds in a period of ten minutes.
Any named storms in the Western Pacific Ocean from 1947 (the start of ordered and stable rotating naming lists, because in 1945 and 1946 names were given randomly without any order) to 1999 with an article goes here. The table is separated by year and gives the first letter of each storm. Bold names indicate retired Western Pacific names from ...
The Northwest Pacific basin covers a vast area in the Pacific Ocean, located north of the equator, between 100°E and 180°E. [1] 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.

^α Although Luis produced the highest confirmed wave height for a tropical cyclone, it is possible that Hurricane Ivan produced a wave measuring 131 feet (40 m). [41]^β It is believed that reconnaissance aircraft overestimated wind speeds in tropical cyclones from the 1940s to the 1960s, and data from this time period is generally considered unreliable.
In the western Pacific Ocean, there have been 4,648 tropical cyclones, including at least 1,485 typhoons; the storms collectively killed more than 1.4 million people. In the North Indian Ocean, there have been at least 1,551 tropical cyclones, including 262 that attained the equivalent of hurricane status; the storms collectively killed over 1 ...
A historic “bomb cyclone” has caused multiple deaths and mass power outages after slamming into Seattle, Washington, as it charts a destructive path through California and Oregon.
For tropical cyclone warning purposes, the northern Pacific is divided into three regions: the eastern (North America to 140°W), central (140°W to 180°), and western (180° to 100°E), while the southern Pacific is divided into 2 sections, the Australian region (90°E to 160°E) and the southern Pacific basin between 160°E and 120°W.
