...NWS DAMAGE SURVEY FOR JUNE 16, 2017 SEVERE THUNDERSTORM WIND
EVENT...

.Southern Sarpy County and Surrounding Areas Wind Damage...

Peak wind:              110-120 mph based on damage indicators
Direction:              From the Northwest
Fatalities:             0
Injuries:               0

Start date:             June 16, 2017
Start time:             7:40 PM CDT

End date:               June 16, 2017
End time:               8:30 PM CDT

A powerful group of thunderstorms produced widespread winds of 60 to
80 mph across much of the area surrounding southern Sarpy county.
Within that broad area of wind, several areas of very intense wind
damage occurred with damage indicators suggesting peak wind speeds
of 100 to 120 mph from the north and northwest.

Perhaps the most intense damage was noted from approximately 3 miles
northwest of Springfield to just west of Springfield to 3 miles south
of Springfield where very large grain bins were dislodged and tumbled
nearly a half mile, many power poles were snapped, and widespread
significant tree damage occurred. Peak winds in this area were likely
in the 110-120 mph range.

Another area of more intense damage occurred in and near the Maha Scout
Camp at 63rd street and the Platte River. Tree damage in this area
indicated smaller areas of locally intense microburst winds which likely
approached 110 mph. Approximately 50 campers were present during the
storm with no injuries reported.

Additional areas of very intense winds occurred in southeast Sarpy county
and adjacent northeast Cass county and western Mills county Iowa to the
south of the EF-2 tornado track. Winds in these areas likely exceeded
100 mph.

Special thanks to local emergency management for assisting NWS storm
damage survey efforts for this expansive severe weather event.

.Gage County and Southeast Saline County Wind Damage...

Peak wind:              100-115 mph based on damage indicators
Direction:              From the North and Northwest
Fatalities:             0
Injuries:               0

Start date:             June 16, 2017
Start time:             8:50 PM CDT

End date:               June 16, 2017
End time:               10:10 PM CDT

A very intense supercell thunderstorm tracked from eastern Saline county
southeast across Gage county. This storm produced 60-80 mph winds
throughout much of its track with a narrower band of 80-115 mph winds
associated with the western rear flank downdraft portion of the storm.
These most intense winds tracked from near Wilber to De Witt to west
Beatrice to Big Indian Creek Reservoir. Damage indicators and radar
data suggest that within this several-mile-wide track there were strong
pulses of wind which produced the most intense damage.

One of the most intense areas was on the southwest side of Wilber where
part of a roof was removed and blown more than 100 yards and a storm
spotter truck was blown sideways approximately 3 feet. Another area of
more intense damage was on the far west side of Beatrice where
substantial tree damage occurred as well as some roof damage to homes
and businesses. The final area of very intense damage occurred
approximately 3 miles northwest of Blue Springs where a barn was
destroyed, the roof of a large shed caved in, several power poles were
snapped, and significant tree damage occurred.

Special thanks to local emergency management for assisting NWS storm
damage survey efforts for this expansive severe weather event.
