Last month saw a record October for tornado outbreaks, with 87 twisters forming in just one three-day span, government meteorologists announced today.

The outbreak, from Oct. 17 through Oct. 19, surpassed the previous record of 63 tornadoes set along the Gulf Coast from Oct. 23 through Oct. 27 in 1997, according to the National Oceanic and Atmospheric Administration (NOAA).

The total number of tornadoes reported in October, 105, came in second behind the 117 tornadoes reported in October 2001. Records go back to 1950.

The massive outbreak occurred because two weather systems that had high potential to form tornadoes were simultaneously positioned over the country.
