ON THIS DATE IN 1999: A total of 74 tornadoes touched down across Oklahoma and Kansas in less than 21 hours. At one point, there were as many as four tornadoes reported on the ground at the same time.
The strongest tornado, rated a maximum F-5 on the Fujita Tornado Scale, tracked for nearly an hour and a half along a 38-mile path from Chickasha through south Oklahoma City and the suburbs of Bridge Creek, Newcastle, Moore, Midwest City and Del City.
As the skies cleared, the states counted 46 dead and 800 injured, more than 8000 homes damaged or destroyed, and total property damage of nearly $1.5 billion.
