Strength is the sustained wind on the track at the closest point, which is not the wind felt in Seven Valleys: a hurricane's worst winds sit within a few dozen miles of its centre, and inland cities are usually past that.

How to read this page
A storm is listed when the centre of its track passed within 75 miles of Seven Valleys while it was at least a tropical storm, which is the reach of damaging wind and rain for a typical hurricane. Being on the list does not mean the city took a direct hit; the "closest" column says how near the centre came. Tornadoes are counted when any part of the path came within 25 miles.
Tornado records before the 1990s are thinner, because weak tornadoes in open country often went unreported before Doppler radar and mobile phones. A rise in the decade counts is mostly better reporting, not a change in the weather.
Tracks come from the National Hurricane Center's HURDAT2 database, tornadoes from the Storm Prediction Center's database. Both are the official federal records and both are revised as old storms are re-analysed.
