You don’t stop a fire like that. With winds that high you don’t have time to set a defense. Dry grass and high winds can reach fire speeds over 15 miles and hour. You have to organize and set up a line 20+ miles out in front of it all the time taking into consideration the line is always moving. Grass fires are the worst it burns fast and sends embers a long ways down wind jumping over fire lines easily. The best you can do is try and defend structures and let it burn on by. We had two big fires on the ranch in 2011 and lost 14 square miles of pasture. We were air dropping water with planes and helo’s and the only way it was brought under control was with a back fires and the fact that it hit thick cedars and slowed it down. Had it stayed in the grass we couldn’t have stopped it. This was with 40 to 50 mile per hour winds. The fires in Colorado have 100+ mph winds pushing them in some places. About the best you can do is hope you get everbody out of it’s way.
That’s kinda the way it sounded on those videos
Just try to do what they can way in front of it
