A tornado warning is an alert issued by national weather forecasting agencies to warn the public that severe thunderstorms with tornadoes are imminent or occurring. It can be issued after a tornado, funnel cloud and rotation in the clouds has been spotted by the public, storm chasers, emergency management or law enforcement. The issuance of a tornado warning indicates that residents should take immediate safety precautions. It is a higher level of alert than a tornado watch, but can be surpassed by an even higher alert known as a tornado emergency or Particularly Dangerous Situation warning.
About Tornado warning in brief
A tornado warning is an alert issued by national weather forecasting agencies to warn the public that severe thunderstorms with tornadoes are imminent or occurring. It can be issued after a tornado, funnel cloud and rotation in the clouds has been spotted by the public, storm chasers, emergency management or law enforcement. When this happens, the tornado sirens may sound in that area if any sirens are present, informing people that a tornado has been sighted or may be forming nearby. The issuance of a tornado warning indicates that residents should take immediate safety precautions. It is a higher level of alert than a tornado watch, but it can be surpassed by an even higher alert known as a tornado emergency or Particularly Dangerous Situation warning. The first official tornado forecast and tornado warning was made by United States Air Force Capt. Robert C. Miller and Major Ernest Fawbush, on March 25, 1948. The USAF had pioneered tornado forecasting and tornado warnings, although the first experimental tornado forecasts were developed in 1885 by John P. Finley. The U.S. Signal Service’s weather service’s forecasts were prohibited from using the word ‘tornado’ in local storms in the 1940s. They were instead directed to refer to severe storms in Great Lakes, New England, and the Carolinas as’severe storms’ and’severe tornadoes’ The first such forecast came after the events that occurred five days earlier on March 20, 1948; Miller – a California native who became stationed at Tinker Air Force Base three weeks earlier – was assigned to work the late shift as a forecaster for the base’s Air Weather Service office that evening, analyzing U.
S. Weather Bureau surface maps and upper-air charts that failed to note atmospheric instability and moisture content present over Oklahoma that would be suitable for producing thunderstorm activity, erroneously forecasting dry conditions for that night. A tribunal of five generals who traveled to Tinker from Washington, D. C., who ruled that the March 20 tornado was an \”act of God not forecastable given the present state of the art\”, tasked Miller and Fawbush to follow up on the board’s suggestion to consider methods of forecasting tornadic thunderstorms. In 1949, they successfully predicted tornadic activity would occur in Oklahoma. The pair would distribute their tornado forecasts to the American Red Cross and Oklahoma Highway Patrol after giving permission to restart their forecasts to restart the relative accuracy of the forecasts. They would later go on to become the chief meteorologist at the U. S. S Weather Bureau’s Oklahoma City office in the 1970s and 1980s. Their forecasts were the first to use the term ‘tornado’ for the first time in more than 20 years. The men would later become known as the ‘Tornado Forecasters’ for their work on tornadic weather forecasts in Oklahoma and elsewhere in the United States. In the 1990s, their forecasts were used by the National Weather Service to forecast tornadoes in other parts of the world, including the United Kingdom and Canada.
