The Beaufort scale (/ ˈ b oʊ f ər t / BOH-fərt) is an empirical measure that relates wind speed to observed conditions at sea or on land. Its full name is the Beaufort wind force scale . History
These warnings use a 1-minute sustained wind speed and can be compared to the Saffir–Simpson hurricane wind scale, however, regardless of intensity in this basin the JTWC labels all systems as tropical cyclones with TC numbers (plus any parenthesized names or placeholders, like typhoons and North Indian Ocean cyclones above).

The Beaufort Wind Scale applies visual clues to gauge how fast the wind is blowing. Watches, advisories and warnings Anytime a significant weather event is expected, the Weather Service will issue ...
Before the 1–5 scale was created in 1969 by the National Hurricane Center and later by the Bureau of Meteorology in Australia, many tropical cyclones were simply ranked by the Beaufort Wind Scale which was created in the early 1800s by Francis Beaufort. The purpose of the scale was to standardize wind reports in ship logs.
Historically, the Beaufort wind force scale, created by Francis Beaufort, provides an empirical description of wind speed based on observed sea conditions. Originally it was a 13-level scale (0–12), but during the 1940s, the scale was expanded to 18 levels (0–17). [ 21 ]
On its website, it said its general view was "that damage can occur even when the wind speed is lower than level 10 on the Beaufort scale", which starts at 48 knots, or 55mph.

The most common way of describing wind force is with the Beaufort scale [3] which defines a gale as wind from 50 kilometres per hour (14 m/s) to 102 kilometres per hour (28 m/s). It is an empirical measure for describing wind speed based mainly on observed sea conditions.
