Tropical Storm Cristobal will bring life-threatening storm surge, tropical storm force winds, inland flooding, brief tornadoes and high surf/rip currents to the northern and eastern Gulf Coast today

An example of wind velocity would be northeast wind at 10 knots since that phrase provides information about both wind direction and its speed. A wind vector can also be represented graphically using any vector form such as a wind barb, dynamic arrow (i.e., variable length is proportional to the wind speed), or plotted graphically as a time series, for example Wind speed on the 1946 Beaufort scale is based on the empirical relationship: v = 0.836 B 3/2 m/s. 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 Knots to Kilometers per hour formula Kilometers per hour. This is a measurement of speed typically used in countries using the metric system for transport. Road speed limits are given in kilometers per hour which is abbreviated as kph or km/h As a general rule in the U.S, wind speeds over land are expressed in miles per hour, while those over water are expressed in knots. This is largely because knots were invented over a water surface, as explained below. Since meteorologists deal with winds over both surfaces, they adopted knots for the sake of consistency Meters per second to Knots formula Knots. Knots are a speed measurement that is nautical miles per hour. This unit is typically used in maritime and aviation. There have historically been different nautical miles used and, thus, different variations of knots
