What the National Weather Service wrote

A 72 foot, 26 inch diameter Douglas Fir fell down from very strong thunderstorm winds and crashed onto owners' house. Soil moisture was relatively dry, but as seen in photo much of the branches on the trunk except at the top had already been cut off before this event. A forester examined the tree and found that its roots had been cut on the west side of the tree before the event.
