The Beaufort Scale was named after Sir Francis Beaufort ( a hydrographer with the Royal Navy ) and lists the effects of increasing wind speeds.
The scale was originally designed to show the effects the wind on a battleship at sea.
When is a hurricane warning issued?
Hurricane warnings are issued when winds reach 12 on the Beaufort scale, but this would only be a category 1 hurricane.
Hurricanes are measured on the Saffir-Simpson scale based on their wind speed.
The scale helps estimate the possible damage a hurricane may cause.
Hurricanes start out over tropical oceans as a tropical cyclone, ( strong, rotating storm ) when they reach speeds on 74 miles per hour they are categorised as a hurricane or a typhoon if they are in the Northwest Pacific.
Hurricane Katrina was a category 5 hurricane at its peak with storm surges over 6m high! Over 1 million people lost their homes and over more than 1000 people died.
New Orleans suffered the worst flooding but the hurricane caused damage in Louisiana, Mississippi, Florida, Georgia and Alabama.
