those missions over to the crash site. let's take a look at some of the conditions expected for the next 24 hours or so. this was the conditions on thursday. as you can see, clear skies for the helicopters as they did the missions, bringing the crews in and out of this very narrow ravine, which is by the way only about 250 meters wide. so leaving very little room for error for the pilots. now, anything below 30 kilometers per hour over a mountainous terrain really flows quite naturally. but when we're talking about wind gusts in excess of 30 kilometers per hour, which we have in the forecast for today, we start to see what is called turbulent eddies. these are circulation patterns that are created by the mountain ravines and all the narrow crevasses. think of it as kind of an analogy. almost like a flowing river of water. that would be the air. as it gets basically damnmed up behind the mountain ranges.
