Tornadoes confirmed in Umatilla County between Weston and Tollgate

PENDLETON, Ore. — Following several days of analysis, the National Weather Service (NWS) has formally classified two tornadoes that touched down in Umatilla County as part of a severe thunderstorm on Friday afternoon.

According to the NWS, the two EF1 tornadoes occurred between 1:40 p.m. and 1:55 p.m. PDT on May 6, 2022, in the northern Blue Mountains of Oregon. NWS officials estimated that the tornadoes moved east along OR-204 in Umatilla County.

The first tornado, which was located roughly eight miles east of Weston, traveled between 1.25 and 1.5 miles, according to the NWS. Weather experts also determined that the second tornado, which was caused by the same storm, touched down roughly another mile to the east of its predecessor and traveled less than a mile before dissipating.

They were each categorized as EF1 tornadoes—the second-lowest of six classifications of active tornadoes on the Enhanced Fujita scale, which rates tornadoes based on intensity and damage.

Weather experts found that several trees were uprooted by the larger of the two tornadoes. Large branches were snapped from many trees in the area and two homes suffered serious damage. One roof was uplifted and carried over 300 feet by the high-speed winds of this tornado. Additionally, the roof and walls of a farm’s outbuilding collapsed in the natural disaster.

NWS officials said that the smaller tornado also uprooted some trees and snapped branches, but did not cause any property damage.
