2014 · On this date in other years · The biggest severe wind days
- A report is a single damage or measurement report to the National Weather Service. Several reports can describe one gust front, so reports are not storms.
- Reporting has grown with population, spotter networks and the internet, so counts from different decades are not directly comparable.
- Thunderstorm wind reports start at 50 knots (58 mph). SPC began flagging measured against estimated speeds in 2006; earlier reports are shown as estimated.
Storm Prediction Center severe weather database, 1955 to 2025. A day is SPC’s calendar date in Central Standard Time; a severe wind day here has 300 or more damaging wind reports, or 15 or more of 75 knots (86 mph) or more.
