List of tornadoes in the 1999 Oklahoma tornado outbreak explained

From May 2 to 8, 1999, a large tornado outbreak took place across much of the Central and parts of the Eastern United States, as well as southern Canada. During this week-long event, 152 tornadoes touched down in these areas. The most dramatic events unfolded during the afternoon of May 3 through the early morning hours of May 4 when more than half of these storms occurred. Oklahoma experienced its largest tornado outbreak on record, with 70 confirmed. The most notable of these was the F5 Bridge Creek–Moore tornado which devastated Oklahoma City and suburban communities. The tornado killed 36 people and injured 583 others; losses amounted to $1 billion, making it the first billion-dollar tornado in history.[1] Overall, 50 people lost their lives during the outbreak and damage amounted to $1.4 billion.[2]

On May 2, a strong area of low pressure moved out of the Rocky Mountains and into the High Plains, producing scattered severe weather and ten tornadoes in Nebraska. The following day, atmospheric conditions across Oklahoma became significantly more favorable for an outbreak of severe weather. Wind profiles across the region strongly favored tornadic activity, with the Storm Prediction Center stating, "it became more obvious something major was looming" by the afternoon hours. Numerous supercell thunderstorms developed across the state as well as bordering areas in Kansas and Texas. Over the following 48 hours, May 3–4, 116 tornadoes touched down across the Central United States. Following the extensive outbreak, activity became increasingly scattered from May 5 to 8, with 26 tornadoes touching down across the Eastern United States and Quebec.[3]

Much of the town was affected, with 170 buildings being damaged or destroyed along with the local high school.[26] Despite the severity of damage, only 22 people due in part to tornado sirens being sounded 15 minutes in advance of the storm. The town was declared a federal disaster area and losses amounted to $125 million. In Arkansas, the tornado remained primarily over forested areas, downing many trees.[27] Overall, the tornado remained on the ground for just shy of two hours along a 71.5miles path.
