TRANSPORT WINDS ARE FORECAST TO BE OUT OF THE SOUTHEAST,
GENERALLY UNDER 10 MPH. IN SPITE OF THE RELATIVELY LIGHT WIND
FORECAST, A VARIANCE MAY STILL BE REQUIRED DUE TO THE REALLY DRY
AIR THAT WILL BE OVER THE AREA. HUMIDITY MINIMUMS AS LOW AS 20%
ARE POSSIBLE ON THE SOUTH FACING SLOPE.
SMOKE DISPERSION WEDNESDAY NIGHT WILL BE POOR, BUT DUE TO
THE LACK OF MOISTURE IN THE AIR, NOT EXPECTING PROBLEMS WITH
