Containment on the Lionshead Fire about 14 miles west of Warm Springs was inched up slightly this morning to 15%, even though the size grew to 203,685 acres.  Fire officials said this morning low fire behavior is expected today even with stronger winds leading up to a predicted rain event.  Southwest winds will build over the ridges prior to rain in early evening.  The increased winds pose a hazard along road corridors and the fireline due to the possibility of falling fire-weakened trees.  Wind can also reveal smokes that need more attention along the fire edge.  Predicted rain, as much as one inch in some areas, will have a positive impact on firefighting efforts.  Approximately 400 additional firefighters and support personnel arrived at the incident yesterday.
