PORTLAND, Ore. (KOIN) — A significant early fall storm is possible this weekend, with heavy rain, high winds and the potential for power outages.
The KOIN 6 Weather team said the weekend looks like it could be very wet and windy, with wind gusts on the coast around 50 mph Saturday. The winds could gust to 35 mph in the valley and bring with it isolated power outages, tree damage and some localized flooding.
Steve Pierce, the president of the Oregon Chapter of the American Meteorological Society, said a strong September jet stream headed toward the Pacific Northwest will start Friday and last through the weekend.
“This is fairly significant by September standards and would be something we would expect to see later in the fall or winter months. The most significant of these systems will arrive Saturday night. Remnants of a tropical typhoon will be entrained into the jet stream which will help add to the precipitation rates across the region,” Pierce wrote.
He said if the model trends play out, there is the “potential for 72 hour rainfall amounts to exceed 6 inches in the mountains and nearing 3 inches in the valleys come Monday morning.”
