Wednesday's damaging wind event could be the worst in many years across Montana. Wind will rapidly increase mid-morning and remain very windy through the evening.

This is going to be a long-duration event with several (8+) hours of damaging wind gusts of 50-60+ mph. Peak wind gusts could reach 60-85 mph for the entire area and 90-100+ mph for the Rocky Mountain Front and high plains.

These gusts will be capable of knocking down trees and power lines, damaging homes, and overturning vehicles towing trailers.
