There I was gaming and right outside my window it went from calm and quiet to hell on earth in about 30 seconds.

From the article:

The tornado ranged back and forth between F-1 and F-2 on the Fujita scale, making it stronger than most of the tornadoes that are documented in the Midwest’s Tornado Alley, Tongue said Thursday.

“Less than 10% of all tornadoes reach F-2,” he said.

It was the first tornado to hit Westchester County since 2000 and just the eighth since 1950, according to a list kept by the National Oceanic and Atmospheric Administration. None of them reached F-2 intensity on the Fujita scale, which ranges from F-0 to F-5. Tongue said there was an F-2 tornado in Long Island’s Nassau County in 1998.
