That is difficult to determine. There have been many thousands of F0 and EF0 tornadoes with winds possibly as low as 40 mph. However it is difficult to determine which were the weakest as many took place in open fields and caused no damage and all but perhaps a few never had their winds measured. Even then, it could be debated whether a tornado with winds as low as 40 mph could actually be counted as a tornado as such winds usually cannot cause significant damage.
The smallest tornado ever recorded on the Fujita scale was likely an EF0 tornado, which has estimated wind speeds of 65-85 mph. Tornadoes at this intensity are usually weak, causing minor damage.
The lowest known pressure recorded in a tornado was 688 millibars in a tornado in Tulia, Texas on April 21, 2007.
The Hallam tornado was a massive F4 tornado that destroyed much of the small town of Hallam, Nebraska on May 22, 2004, killing 1 person. The tornado is notable in that at one point it was 2.5 miles wide, making it the largest tornado ever recorded.
The first recorded tornado occurred near Kilbeggan, Ireland on April 30, 1054.
It is impossible to say when the first ever tornado was, as they have been occurring since long before there were people around to record them. The first recorded tornad struck near Kilbeggan, Ireland on April 30th, 1054.
The Hallam, Nebraska tornado of May 22, 2004 was the widest tornado ever recorded. It was 2.5 miles wide.
No. No tornado stronger than F5 has ever been recorded.
the tornado was recorded in kilbeggan Ireland in Europe on April 30th 1054
The largest tornado in Oklahoma (and in fact the largest tornado ever recorded), was the El Reno, Oklahoma tornado of May 31, 2013. It was 2.6 miles wide.
The smallest tornado ever recorded on the Fujita scale was likely an EF0 tornado, which has estimated wind speeds of 65-85 mph. Tornadoes at this intensity are usually weak, causing minor damage.
The deadliest tornado ever recorded was in Sandwip island of the coast of Bangladesh in1989.
The largest tornado ever recorded was the El Reno, Oklahoma tornado of May 31, 2013. This tornado was 2.6 miles wide. Doppler radar measured a wind gust in the tornado at 296 mph, the second highest wind speed ever recorded in a tornado.
