Episode Narrative Atmospheric conditions favored the downward mixing of higher winds from above as a very strong pacific jet stream emerged eastward over the continental divide. Some funneling was noted, especially along the higher terrain near the Little Rocky Mountains.
Event Narrative Sustained winds of 35 to 45 mph were common across the county with gusts often reaching over 50 mph both at the Dawson Community Airport KGDV AWOS site and the Lindsay Divide DOT site.
