EF2 tornado, Hughes Spgs to Atlanta Muni Arpt, Texas, April 9, 2009

From Hughes Spgs to Atlanta Muni Arpt, this EF2 tornado ran 16.8 miles across Cass County on April 9, 2009, touching down at 8:05 PM CDT and reaching 190 yards wide. It killed nobody, and did $750,000 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 mph

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

  3. EF2111 to 135 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. 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 storm system along with a surface dry line/front |over northeast Texas moved east during the evening hours of April 9th into the early morning hours of April 10th causing long lived supercell thunderstorms. These thunderstorms caused long track tornadoes to occur across southeast Oklahoma, southwest Arkansas, northeast Texas, and north Louisiana.

This storm developed about 100 yards inside the Morris County line, very near the Cass County line, about 5 miles northwest of Hughes Springs. This tornado first touched down just west of County Line Road near FM 130 in eastern Morris County, continuing east across CR 2865, before lifting near FM 250 north of FM 130. Numerous trees were uprooted and snapped, with power lines downed as well. This tornado was rated an EF1, with winds of around 90 mph.

This storm developed about 5 miles northwest of Linden in central Cass County near CR 1459 around 8:05 pm. Numerous trees were downed, with a tree crushing a truck, and another tree falling through the roof of a house. This tornado intensified along CR 1399, where a two-story home was nearly destroyed. The storm continued east across Highway 8 about 2 miles north of Linden, where the roof of a two story house was torn off, and a portable building behind the home was blown nearly 400 yards east across Highway 8 into some nearby woods. The tornado lifted around 8:31 pm near the intersection of CR 2328 and Highway 43 about a mile and a half north of Bivins. This tornado was rated an EF2, with winds around 125 mph. The path length was nearly 16 miles long, with a path width of 190 yards.

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

The forecast that day

The Storm Prediction Center had this point in a Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 00:55 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.
