May Tornadoes

May Tornado 1959 to 2006May 1959 to 2006            
Total Reported Tornadoes 14792 with   
24 F5    200 F4     717 F3   2417 F2   4704 F1    6730 F0
Of the total tornadoes 23% would be classified as strong/violent during this period which is a drop in percent of violent tornadoes from the month of April which was a high 28%.  48 States in the US have recorded tornadoes in May since 1959.   It is incredible that 113 of these tornadoes have had a track length of greater than 50 miles.  During May 1731 deaths have been recorded from these tornadoes from 1959 to 2006. By this time of year our tornado map is getting painted in with red because of the high number of tornadoes reported in May.

May is a typical month that all storm chasers will be out.  Of all the months of the year that storm chasers are found chasing storms, this month is the busiest often bringing hundreds of chasers on one storm at the same time. 

May 2003 was particularly deadly as seen in this SPC listing
