Beaufort scale used in Taiwan and mainland China, which are often affected by typhoons. Internationally, WMO Manual on Marine Meteorological Services (2012 edition) defined the Beaufort Scale only up to force 12 and there was no recommendation on the use of the extended scale. Wind speed on the 1946 Beaufort scale is based on the empirical relationship: Where "v" is the equivalent wind speed at 10 metres above the sea surface and "B" is Beaufort scale number. For example, "B" = 9.5 is related to 24.5 m/s which is equal to the lower limit of "10 Beaufort". Using this formula the highest
1925 Florida tropical storm by the storm as vessels were forced to seek shelter at port. Due to the large size of the storm as an extratropical cyclone, gale and storm warnings in force from Beaufort, North Carolina to Eastport, Maine. In North Carolina, heavy rains and strong winds were reported along the coast. Near record high water rises were recorded around Wilmington. Cape Hatteras was temporarily isolated from the surrounding areas as the high winds from the storm knocked down power lines throughout the area. Several buildings along the coast and numerous boats sustained considerable damage. As far north as New Jersey, gale-force
