...NWS DAMAGE SURVEY FOR 08/08/2025 THUNDERSTORM WIND EVENTS IN
   JAMESTOWN AND NORTH OF COURTENAY IN STUTSMAN COUNTY...


.OVERVIEW...
Severe thunderstorms struck much of North Dakota during the evening
hours of Thursday, August 7, 2025 into the early morning hours of
Friday, August 8, 2025, causing widespread wind damage. The
National Weather Service in Bismarck conducted a storm survey
on Friday, August 8, 2025, to survey two areas of significant damage.

The first area surveyed was at Jamestown in Stutsman County, ND.
Significant damage, primarily to trees, occurred over the
southern part of the city. The area with the greatest damage was
generally between Foxtrot Road on the west and and 10th Avenue
East on the east, resulting in a path length of approximately
two miles. The width of the greatest damage stretched from near
17th Street on the south end to around 11th Street on the north,
approximately one-half mile. At the start of the greatest
damage in the vicinity of Meidinger Park and areas south, a
pontoon boat was flipped, a tree was uprooted, multiple smaller
trees were either snapped or had significant branches broken
off, and a camper was pushed off its blocks. Towards the east
near the intersection of 14th Avenue SW and 17th Street SW, a
manufactured home had its roofing material uplifted, and larger
spruce trees were uprooted. Continuing east passing over the
Interstate 94 Business Loop, multiple trees were uprooted
including spruce trees along the loop. Further east along 17th
Street SE, the metal roof panels blew off the east side of a
building towards the northeast and across the road. At McElroy
Park and areas surrounding, many trees were uprooted, with some
smaller to medium size trees snapped. To the east near the
intersection of 14th Street SE and 8th Avenue SE, an L-shaped
building had its east side roofing panels blown off. Based on
the damage, it was determined that straight line thunderstorm
winds caused the damage, with speeds up to 100 mph between 234
PM CDT and 238 AM CDT.

The second area surveyed was a farmstead approximately 7 miles
north of Courtenay in Stutsman County, ND. At this site,
significant damage occurred to buildings and grain handling
equipment. Two newer pole-barn buildings had a significant
portion of the structure destroyed with collapsed walls and
roofs. The damage was primarily on the west side of both
buildings. Another large building had multiple roof panels on its east
side blown off. Multiple grain bins were damaged, one suffering
very significant damage to its roofing structure. A large grain
dryer was toppled when the grain leg system collapsed. Based on
the damage, it was determined that straight line thunderstorm
winds caused the damage, with speeds up to 100 mph between 244 AM CDT
and 248 AM CDT.

The National Weather Service extends great appreciation to the
City of Jamestown Forester, the Stutsman County Emergency
Manager, and to the residents and neighbors of the impacted
farmstead north of Courtenay. Their assistance was very valuable
in determining what happened during this event.
