F0 tornado, Crystal River to Hernando, Florida, March 29, 2001

From Crystal River to Hernando, this F0 tornado ran 10.3 miles across Citrus County on March 29, 2001, touching down at 10:05 AM EST and reaching 100 yards wide. It killed nobody, and did $200,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. F040 to 72 mphthis tornado

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. F2113 to 157 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. F3158 to 206 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. F5261 to 318 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

  7. Unrated

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded

National Weather Service damage survey indicated that a high end F0 tornado, that averaged 50 yards in width, touched down and caused heavy roof damage to a mobile home along West Jennifer Court, east of County Road 495. The tornado continued northeast and sporadically touched down on North Fairport Avenue near West Dunklin Street where minor to moderate damage occurred to rooftops, sheds and lanais, including several downed pines trees and large branches. Also, the tornadic winds rolled over one mobile home along the 4500 block of North Fairport near West Dunklin Street.The tornado continued northeast and caused sporadic damage to mainly roof tiles, shingles, lanais and trees in and along the Citrus Springs Country Club. The tornado downed a few additional trees and large branches near County Road 39 and North Perkins Path before it lifted and dissipated.

Citrus county emergency management reported that a F0 tornado initially touched down near East Bryant Street and North Croft Avenue, two miles south-southwest of Hernando, and sporadically touched down as it moved northeast across mixed residential neighborhoods near U.S. Highway 41. The tornado continued northeast, then lifted and dissipated near East Parson Point Road, one mile east of Hernando. The tornado caused mainly minor damage to roof tiles, awnings, sheds, lanais of homes and toppled a few trees along its narrow path. A woman was injured from shattered glass when wind blown debris broke her vehicle's windshield along North Croft Avenue.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The forecast that day

The Storm Prediction Center had this point in a Slight Risk. The outlook in force was issued at 13:17 UTC.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
