A severe tropical storm is designated as a tropical cyclone when it reaches wind speeds of 64 knots (119 km/h; 74 mph). If a tropical cyclone intensify further and reaches wind speeds of 90 knots (170 km/h; 100 mph), it will be classified as an intense tropical cyclone.
The Tropical Cyclone Warning Signal was then renamed "Tropical Cyclone Wind Signal" in 2019 to emphasize that this warning system is based on tropical cyclone wind intensity rather than rains, flash floods and landslides (for which other weather warning systems, particularly the PAGASA Heavy Rainfall Warning System, are already in place).

Pressure-wind relations can be used when information is incomplete, forcing forecasters to rely on the Dvorak Technique. [6] Some storms may have particularly high or low pressures that do not match with their wind speed. For example, Hurricane Sandy had a lower pressure than expected with its associated wind speed.

Former Hurricane Hilary was actually no longer a tropical storm but essentially had the same impact when its destructive remnants entered California last August, according to a new National ...
