550 NOUS45 KBOU 211716 PNSBOU COZ030>051-220530- Public Information Statement National Weather Service Denver/Boulder CO 1116 AM MDT Wed May 21 2025 ...NWS Damage Survey for 05/18/25 Tornado Event... .Overview...Four tornadoes occurred just to the south and east of metro Denver in the early afternoon of Sunday, May 18th. The first tornado that produced damage in northwest Elbert County was an uncharacteristically strong landspout, as well at the last tornado that occurred north of Bennett. The other two tornados were more strongly associated with a parent thunderstorm, known as a supercell. The following information is for four separate tornado tracks surveyed on May 19th. The first is for the initial tornado, rated EF2, in and near the Elkhorn neighborhood of extreme northwest Elbert County, Colorado. The second is an EF1 that occurred south of Manila Village. The third and fourth tornadoes were both ranked EF2. These tornadoes tracked just to the west and north of Bennett, Colorado. They were two separate tornadoes, and were both on the ground at the same time between 140 pm and 146 pm. All data is preliminary and subject to change as new information is received. .Elkhorn Ranch...

A long lived supercell produced three tornadoes across Logan and Washington counties during the afternoon hours of May 23rd, including one EF-2 and one EF-1. Most of the observed damage was snapped power poles and trees. One single family residence sustained EF-1 damage, but there were no injuries reported. This supercell also produced a swath of golf ball to baseball sized hail, with one ICECHIP report of over 3 inch diameter hail in northern Washington county. .Near Messex... Rating: EF1 Estimated Peak Wind: 100 mph Path Length /statute/: 10.68 miles Path Width /maximum/: 100 yards Fatalities: 0 Injuries: 0 Start Date: 05/23/2025 Start Time: 05:09 PM MDT Start Location: Willard / Logan County / CO Start Lat/Lon: 40.5456 / -103.4757 End Date: 05/23/2025 End Time: 05:28 PM MDT End Location: 2 NNW Messex / Washington County / CO End Lat/Lon: 40.402 / -103.4015 Survey Summary: The formation of this tornado was captured well by storm chaser video. The tornado did not have a coherent damage path. There was sporadic damage south of the South Platte River, primarily to a trio of grain silos. Two silos had their tops removed, one was shifted off the pad, another was destroyed. One off duty NWS employee confirmed the location of the tornado as it crossed Logan County Road R just south of County Road 59. The tornado dissipated just southwest of the Prewitt Reservoir with no evidence it crossed I-76. .Rural Washington County... Rating: EF2 Estimated Peak Wind: 118 mph Path Length /statute/: 8.72 miles Path Width /maximum/: 400 yards Fatalities: 0 Injuries: 0 Start Date: 05/23/2025 Start Time: 05:37 PM MDT Start Location: 5 SE Prewitt Reservoir / Washington County / CO Start Lat/Lon: 40.3814 / -103.2747 End Date: 05/23/2025 End Time: 05:59 PM MDT End Location: 3 E Fremont Butte / Washington County / CO End Lat/Lon: 40.2599 / -103.2539 Survey Summary: Well documented tornado that moved south parallel to CO-63, remaining generally in open areas 2-3 miles west of CO-63. We obtained the width (400 yds) of the tornado based on power poles snapped along County Road 50. One single family residence was struck with EF-1 damage to the house, along with EF-1 damage to all outbuildings and trees on the property. Debris from the property was carried approximately one mile to the south- southwest. Further south of the damaged property, power poles were snapped and thrown a considerable distance (~25 yds), consistent with EF-2 intensity. The power poles were on the west side of County Road AA, just north of County Road 48. Video evidence and the results of the storm survey suggest that the tornado dissipated just before 6 PM MDT. .Southeast of Akron... Rating: EFU Estimated Peak Wind: 0 mph Path Length /statute/: 0.51 miles Path Width /maximum/: 30 yards Fatalities: 0 Injuries: 0 Start Date: 05/23/2025 Start Time: 06:10 PM MDT Start Location: 2 SSE Akron / Washington County / CO Start Lat/Lon: 40.1355 / -103.1898 End Date: 05/23/2025 End Time: 06:13 PM MDT End Location: 3 SSE Akron / Washington County / CO End Lat/Lon: 40.1281 / -103.1884 Survey Summary: Storm chaser video confirms the existence and general location of this short lived tornado. It remained over open fields. && EF Scale: The Enhanced Fujita Scale classifies tornadoes into the following categories: EF0.....65 to 85 mph EF1.....86 to 110 mph EF2.....111 to 135 mph EF3.....136 to 165 mph EF4.....166 to 200 mph EF5.....>200 mph NOTE: The information in this statement is preliminary and subject to change pending final review of the events and publication in NWS Storm Data. $$
