AUMSVILLE, Ore. - The tornado that hit Oregon Tuesday tore a path 5 miles long and 150 yards wide, delivering winds estimated at 120 mph, the National Weather Service said.
Meteorologists have been piecing together the evidence to paint a picture of Tuesday's tornado:
11:46 a.m. National Weather Service radar detects a strong cell north of Stayton, Ore.
11:52 a.m. A report of a 2-foot diameter Fir tree down on Highway 22
11:53 a.m. Weather service issued a Severe Thunderstorm Warning for the storm
11:59 a.m. Emergency personnel report a tornado in Aumsville with damage
12:02 p.m. Tornado Warning issued for the storm
After the tornado warning:
- The storm hit Aumsville and continued moving, skipping over a section of ground before doing more damage, missing contact with the ground for a distance before doing more damage northeast of Aumsville.
- The storm damaged at least 50 structures and uprooted or snapped over 30 large trees.
- Only two minor injuries were reported.
- The storm survey estimates the wind speeds at 110 to 120 mph.
- Given the damage and the wind speed, the tornado qualifies as an EF2, or significant tornado, on the Fujita Tornado Damage Scale developed in 1971 by T. Theodore Fujita of the University of Chicago.
