we were talking yesterday at the kwan oneffect and what happened with the air and why winds are such a factor. when the wind gets channelled through the canyon the air gets squooed squeezed and it accelerates, similar to walking in a big city and you walk between a narrow passage way and the winds pick up. the topography is making that so. you can see denoted in the blues where the heaviest and the strongest winds are. right now they re to the east. here is where the rim fire is. today s winds again with a southerly component when we talk about wind we talk about the direction from which they come. when they come from the southwest they blew this way. and so that s of course the direction this fire is moving bringing it into the northwest quadrant of yosemite.
