One of the most damaging northeast wind events in the past several decades occurred across western Montana. Wind speeds nearing 70 mph caused acres of downed trees and subsequent power and residential infrastructure damage.

A local utility remarked that this was one of the most damaging storms they've ever experienced. The owner of a tree farm, located north of Echo Lake, stated to a local newspaper that he had never seen such damage since 1958. The Echo Lake area was one of the most hard hit: four houses had minor structure damage, one truck and trailer were totaled, and one mobile home had moderate to severe damage. Dozens of trees, mostly pines and firs, some estimated to be 100 feet tall and three feet wide, were reported to have fallen in this area. One resident was sleeping when a tree fell onto his house into his bedroom, but escaped unharmed. Sporadic tree damage and power outages were reported in the Columbia Falls to Lake Blaine areas. There were dozens of fallen large trees, as well as broken power poles and lines, along Highway 83 between Ferndale and Swan Lake. One resident reported at least 10 fallen trees on their property, with one 80 foot tree damaging their garage. Multiple trees, some snapped in half and some uprooted, went down over Highway 35 between mile-markers 19 and 23, causing damage to telephone and power lines. This also caused the highway to be closed for two hours. Several homes were damaged and in one case, a large tree smashed through the roof and lower room of a home, but didn't cause any injuries. Three large trees, up to three feet in diameter, took out a power line on Finley Point.

There were multiple locations along the western foothills of the Whitefish Range that were impacted by the high winds. At the end of Burma Road, residents estimated at least 5 acres of pine and fir trees were blown down. This caused some roof damage to several homes. A metal roof partially peeled off of a trailer home located due west, across US-93 on Acres Lane. Billboard signs were blown down between Eureka and the Canadian Border. The utility company reported two power poles damaged, and power was out for 20 hours. In the Glen Lake area, five miles east of Eureka, countless trees were strewn all over the roads, especially along Stevens and Therriault roads. At one point, emergency vehicles couldn't immediately get to a person who was on oxygen. A power company reported that they lost 8 span of power line and 8 power poles in the Graves Creek drainage area, where they reported that at least 1500 yards by 500 yards of trees blown down. They were cleaning up the damage for a few weeks after the event. They estimated that 20 log truck loads would come out of there. Multiple trees in the Dickey Lake area also had fallen on power lines. The highway department reported dozens of trees down five miles south of Troy, or between mile-markers 30 and 32 on Highway 56. A tree fell on a utility truck in this area, but no one was hurt.
