EF1 tornado, Nome, Texas, June 9, 2010

This EF1 tornado ran 2.8 miles across Jefferson County on June 9, 2010, touching down at 5:32 AM CDT and reaching 100 yards wide. It killed nobody, and did $100,000 of property damage.

The rating scale

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

  1. EF065 to 85 mph

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

  2. EF186 to 110 mphthis tornado

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

  3. EF2111 to 135 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. EF3136 to 165 mph

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

  5. EF4166 to 200 mph

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

  6. EF5over 200 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

A strong upper level low pressure system over central Texas spawned isolated showers and thunderstorms across southeast Texas during the early morning hours on June 9. One of these thunderstorms moved nearly due north from the Gulf of Mexico across western Jefferson County and produced an EF1 tornado in the town of Nome.

An NWS Storm Survey found a low-end EF1 tornado struck the eastern part of Nome. The tornado began southwest of Rodeo Drive in the southeast part of Nome and moved north-northeast, causing minor damage to a rodeo arena. Several outbuildings were then damaged or destroyed on the west side of FM 365 with debris thrown up to 200 yards to the north-northeast. The tornado then entered the Silver Spur Mobile Home Park, where one mobile home had its side sheared off and a nearby RV was flipped over onto a vehicle. The occupants inside were not injured. Another mobile home lost much of its roof, while several other mobile homes suffered various degrees of siding, window, and awning damage. Two homes at the intersection of Kotz Road and FM 365 received roof and siding damage along with broken windows. Crossing FM 365, the tornado then caused minor roof damage and broken windows to several homes on the east side of the highway, and destroyed two barns. 2X4s from one of these barns were carried up to 100 yards to the west and driven several feet into the ground. The tornado crossed Highway 90 just east of the FM 365 intersection with damaged trees and embedded sheet metal noted north of the railroad tracks. Entering open farm fields, the tornado deposited sheet metal from one of the previously destroyed barns up to 1/2 mile north of Highway 90 before it dissipated.||In total, a Red Cross survey found up to 30 homes suffered some degree of damage, and of those 2 were considered destroyed and 3 had major damage. Dozens of trees and power lines were blown down all along the path in all different directions. No injuries were reported. Numerous local residents witnessed the tornado.

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

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 General Thunderstorms Risk. The outlook in force was issued at 06:00 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
