Note: Start and end times above are approximate and are estimated
from a combination of radar data, and timestamps on videos from 
several members of the public who captured the event.

The only discernible damage was to numerous trees, mostly small
and medium size branches. There were 5 trees (all pine or poplar) 
noted that were either snapped off, or uprooted. The most 
significant property damage was noted near Royer Road in Damascus,
where a large poplar tree was uprooted from very wet soil. This
tree subsequently landed on parked vehicles, significantly 
damaging three of them. Otherwise, no structural damage to homes, 
roofs, windows, or outbuildings was observed.

The National Weather Service in Portland would also like to
sincerely thank the many members of the public who shared video
and pictures of this tornado; and also the several residents who
shared their stories and experiences with us today on the damage
survey. All of this information was very helpful in documenting
this event.

Finally, a graphic with a damage map and other pertinent
information as outlined above should be available by 330 PM PDT
Sunday via the NWS Portland webpage and social media accounts.
