Trees across the road in Nielton have the National Weather Service asking for photos of a possible tornado event over the weekend. In a Monday-morning update, administrators said that an evaluation of the photographic evidence from local officials and the trained spotter combined with radar signatures from the event are consistent with a brief tornado. Based on the location and path length the tornado most likely touched down at 4:40 am and lasted for less than 2 minutes, traveling 0.50 miles with a maximum width of 30 yards. The degree of tree damage is consistent with peak winds of approximately 90 MPH, rating it as an EF-1 tornado on the Enhanced Fujita scale.

The National Weather Service in Seattle posted to their Facebook page that between approximately 4:35 – 4:45 AM on the morning of October 10, radar indicated rotation capable of producing a tornado approximately 5 miles southwest of Neilton, WA in Grays Harbor County. In addition, a single radar scan indicated the potential for lofted debris.

A Tornado Warning was issued at 4:40 AM and was in effect through 5:00 AM. The Grays Harbor County Emergency Management Agency posted to their Facebook page Saturday morning, “Earlier this morning at 4:40 AM, the National Weather Service-Seattle issued a Tornado Warning for a severe thunderstorm capable of producing a tornado near the Amanda Park area.

The NWS said that evidence currently available cannot conclusively determine whether the tree damage was caused by a tornado or strong winds associated with the storm. NWS Seattle is working with local authorities to determine if a damage survey is needed for this event. Until the NWS confirms whether this was a tornado, there will be no preliminary rating given to the event.
