Beaufort scale issued if winds of Beaufort force 9 or frequent gusts of at least 52 knots are expected.; "Storm Force Warnings" are issued if Beaufort force 10 or frequent gusts of at least 61 knots are expected; "Violent Storm Force Warnings" are issued if Beaufort force 11 or frequent gusts of at least 69 knots are expected; "Hurricane Force Warnings" are issued if winds of greater than 64 knots are expected. This scale is also widely used in the Netherlands, Germany, Greece, China, Taiwan, Hong Kong, Malta and Macau, although with some differences between them. Taiwan uses the Beaufort scale with
Burns' Day Storm the Netherlands and Belgium. The strongest sustained winds recorded were between 70 and 75 mph (110–120 km/h), comparable to a weak Category 1 hurricane or Hurricane-force 12 on the Beaufort Scale. Strong gusts of up to 104 mph (170 km/h;) were reported, and it was these which caused the most extensive damage. The Burns' Day Storm of 1990 has been given as an example of when the Met Office "got the prediction right". The model forecast hinged on observations from two ships in the Atlantic near the developing storm the day before it reached the UK. During the day of
