EF1 tornado, Cypress to Houston Weiser Arpt, Texas, May 16, 2024

From Cypress to Houston Weiser Arpt, this EF1 tornado ran 1.4 miles across Harris County on May 16, 2024, touching down at 6:08 PM CDT and reaching 100 yards wide. It killed nobody, and did $500,000 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.

The damage survey

21 damage points were recorded along this path by NWS HGX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 116 mph.

  • Power pole snapped, fence down.
  • Multiple homes with similar damage to roofs, windows.
  • Pair of metal transmission towers complete collapse on either side of hwy290. Likely 115 mph winds near top of towers. Likely 80-90 mph max at surface.
  • Homes severely damaged near corner of Longhorn Point Drive and Hill Country Oaks Lane. Photos courtesy of KPRC.

What the Weather Service recorded

On the evening of May 16, a derecho moved into SE TX. This resulted in extensive wind damage across much of the Greater Houston area, including much of Downtown Houston. Maximum wind gusts were estimated to have reached over 100 mph. Additionally, the system produced two tornadoes and widespread flash flooding. Power outages resulting from the derecho lasted multiple days for hundreds of thousands of people.

Damage path constructed for photos and videos from residents and broadcast media. Rated high end EF1 based on severe damage to 3 houses on NW side of track.

This tornado touched down near the intersection of Tuckerton and Greenhouse Roads then tracked southeastward through Highlands subdivision. Numerous single family homes had roof damage and broken windows. The damage path was well defined. Additional damage was found across Lone Star College Campus and CyFair ISD facility.

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

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 Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:53 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.
