From the record
What the reports say
Written by National Weather Service staff at the time of the event · public domain
Hundreds of trees were downed in and around Wilson WY. Some trees landed on power lines, resulting in a loss of power for several hours in Wilson. Pictures shared by emergency management showed fallen trees which had damaged homes, businesses, and vehicles.
Thunderstorm outflow wind descended the east slopes of the Teton Range and generated a swath of damage from near Wilson north along the Moose-Wilson Road and through Grand Teton National Park. The damage began near Wilson around 1645MST and spread north until shortly after 1700MST. Downed trees damaged power lines, crushed parked vehicles, made roads impassable, and even stranded park visitors on the Signal Mountain Summit Road. Just under 1000 customers were impacted by power outages due to the downed power lines, including park employee housing at Beaver Creek. In all, over 150 trees were cleared and all park visitors were rescued by 2200MST.
A microburst associated with a strong thunderstorm that developed near Rafter J Ranch and swept north caused widespread tree and property damage. Most of the damage was concentrated in Jackson and in a swath from south of town to the northwest of town toward Teton Village. Dozens of uprooted trees caused minor roof damage and a carport collapsed at Jackson Hole Lodge in Jackson.
