11 damage points were recorded along this path by NWS OTX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 88 mph.

• Large section of tree broke off and fell to the NNE. Some rot noted in where the tree snapped.
• Woody debris found east of tree damage. First evidence of tornado.
• Large tree fell to the southeast across a fence and into the street. Talked to owner of property where the tree was pointed but no wind damage on their property.
• Multiple trees snapped approximated 30 to 50 ft above ground and fell to the east-southeast. No property damage directly across the street.

Strong storms developed to the west of Spokane during the early evening hours of 6 May 2022. As they approached the west side of the metropolitan area, the storms became more organized. The strongest cell developed rotation periodically as it moved from the Airway Heights area eastward through Spokane and Spokane Valley. Two distinct areas of damage occurred due to tornadoes as the storm moved through the region.

Tornado followed a due west-to-east path along W. Greenwood Road. The damage indicators along the road mainly consisted of trees that were uprooted or snapped. Several powerline poles were brought down by fallen trees toward the middle of the damage path. No substantial damage was noted to structures along the path. A video that was shared by a resident near N. Kynan Rd. showed a very weak circulation moving due east along W. Greenwood Rd. This video footage confirms the timing and width of the tornado. Residents in the vicinity of Russell Rd. confirmed no further damage beyond this point.

Tornado generated a discontinuous line of damage first observed near the intersection of E. 9th Avenue and S. Cuba St. Video footage confirms a funnel cloud lowered at times and was disorganized as it moved from west to east. A second area of more significant damage was observed along 6th Avenue that included roof damage and many trees uprooted or snapped at the base. The third and longest track of damage began near E. 5th Ave and S. McKinnon Rd and included significant damage to trees and unsecured items along E 4th Avenue. The most noteworthy damage along E. 4th Ave was to a line of travel trailers, vehicles, and boats, several of which were tossed or displaced. Numerous large ponderosa pine trees were uprooted or snapped along E. 4th Avenue before the tornado again lifted. The final isolated area of damage was located along E. 5th Avenue between S. Coleman Rd and S Grand Rd. Security camera footage confirmed brief circulation at the surface along with two downed trees along the southern edge of the track before the tornado lifted for the final time.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The Storm Prediction Center had this point in a General Thunderstorms Risk. The outlook in force was issued at 01:06 UTC.

13 more were confirmed in the United States that day.

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
