The first tornado warning was issued on March 20, 1948 for a storm that produced a tornado in the Oklahoma City area.
A tornado watch means that general weather conditions are right for tornadoes to form in a region. On March 26, 2017 such conditions began to develop across much of Oklahoma and a portion of northern Texas. A tornado warning means that a tornado has been detected or a storm may produce one soon. A tornado warning was issued for Ada when a rotating thunderstorm capable of producing a tornado developed in the area. A possible tornado was later spotted with this storm.
As of 12:30 EDT on March 18, 2013 Spring City, Tennessee is not under a tornado watch. It is, however under a severe thunderstorm watch. A tornado warning has been issued near Lewisburg, though that is some distance from Spring City.
Yes! San Antonio Texas is "at risk", but the last "Tornado Warning" for that area was in March of 2002. See the link below to see the map of Tornado Alley.
Currently, on the afternoon of March 19, 2011 Irving, Texas is under a tornado watch. That means general conditions are favorable for the formation of tornadoes. However, even under a tornado watch the chances of a tornado hitting any given town are low. So while Irving probably will not get hit today there is no way of knowing for certain. Since tornado watch has been issued there is some risk. Pay attention to weather broadcasts and check the National Weather Service at the link below. You can read the posted warnings there and pay attention to any mention of Irving or Dallas County. If a tornado warning is issued for your area take cover.
There were two significant tornadoes on March 20, 1948, both in the Oklahoma City area. The first, an F3, caused major damage to Tinker Air Force base. This tornado prompted the first ever tornado warning. The second tornado, an F2, touched down on the air base and damaged several buildings there before moving to other parts of the metro area.
There is no particular year. The first advisory for tornadoes, which today would be called a tornado watch, was issued on March 25, 1948 in central Oklahoma. It was not called a tornado watch then as it was an impromptu alert given by an Air Force meteorologist rather than official watch.
Three tornadoes that ocurred are rather notable in this regard.The Oklahoma City tornado of March 20, 1948. This tornado struck Tinker Air Force base after being predicted by what was essentially the first tornado watch.The Waco, Texas tornado of Mary 11, 1953. This F5 tornado tore through the city of Waco without warning, killin 114 people. The high death toll and lack of warning prompted the beginnings of the development of an early warning system.The Wichita Falls, Texas tornado of April 10, 1979. This F4 tornado killed 42 people in and near Wichita Falls, many of whom were trying to flee. This demonstrated that attempting to evacuate efore a tornado often puts people at greater risk.
