Damaging Wind Storm Possible for Northern Ontario on Thursday With Gusts Up to 110 KM/H

We’re tracking the potential for a destructive wind storm throughout much of Northern Ontario. The impacts of this second wind storm will vary depending on location, but it appears the damaging wind gusts will be strongest along the Lake Superior shoreline and into Northeastern Ontario. We’re quite concerned about the wind damage and power outage potential based on the latest data which has further increased the strength of the expected wind gusts.

The latest data shows widespread wind gusts exceeding 90km/h throughout Northeastern Ontario. We could see guests exceed 100km/h in locations including Thunder Bay, Marathon, Wawa and Sault Ste. Marie during the morning hours. The southern portion of Northeastern Ontario will see gusts ranging from 90-105km/h with less of an impact the further northwest you go in the region. Northwestern Ontario isn’t expecting much in terms of wind gusts from this system. However, Northwestern Ontario will see some heavy rainfall with between 20-40mm possible by the end of Thursday in locations such as Atikokan, Sioux Lookout and Armstrong.

We will see the wind begin to pick up during the early morning hours of Thursday for Southwestern Ontario as the deepening low-pressure system that spawned a line of destructive storms across the US Midwest moves into Northern Ontario. The wind gusts will continue to get even stronger later in the morning with the worst conditions expected during the mid to late morning. We should see the wind gusts slowly die down by afternoon however they will remain quite strong through the afternoon ranging from 60-80km/h.
