It happened 15 years ago today. It was a day in weather history that simply can’t be compared to any other day. In fact, it was our nation’s biggest Tornado Super Outbreak of all time. Unfortunately, Alabama was Ground Zero. By far, the hardest hit state – with 62 tornadoes and 252 deaths. Nationally, on that day, there were 218 tornadoes and 317 deaths. Even surpassing 1974, the previous benchmark.

But, it’s not just the number of tornadoes. It’s the prolific number of violent tornadoes. On that day, there was an unprecedented 4 EF-5’s. An EF-5 is very rare indeed. There were 11 EF-4’s, and 19 EF-3’s. That’s more “significant” tornadoes than any other day in history
