F2 tornado, Ruther Glen, Virginia, April 1, 1998

This F2 tornado ran 4.0 miles across Caroline County on April 1, 1998, touching down at 7:06 PM EST and reaching 200 yards wide. It killed nobody and injured 1, 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 mph

    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 mphthis tornado

    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

Supercell thunderstorm produced a tornado along a 9 mile path extending from near Coatesville in northwest Hanover county eastward into south central Caroline county southeast of Ruther Glen. The damage path was nearly continuous along this track, with damage intensity ranging from F0/F1 to strong F2/F3 in a couple of locations along the path. Damage path ranged from about 200 yards wide to near one quarter of a mile wide at its widest. The most significant structural damage occurred to two homes east of Coatesville. One home was completely destroyed and another severely damaged. Numerous other homes in northwest Hanover and south central Caroline counties sustained lesser damage. In addition, two mobile homes were destroyed in Caroline county. Several churches sustained damage, and several outbuildings were severely damaged or destroyed. There were two areas along the tornado path where entire groves of pine trees were completely flattened by the tornado. There were two fatalities from the storm in the Coatesville area of northwest Hanover county and one minor injury in Caroline county.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

16 minutes of warning. NWS AKQ issued a tornado warning for this county at 23:50 UTC, 16 minutes before the tornado touched down, in force until 00:15 UTC.

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 10:42 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.
