...SPOT FORECAST FOR RED ROCK COMPLEX...

.DISCUSSION...

VERY WARM AND DRY CONDITIONS WILL CONTINUE TODAY WITH
UPSLOPE/UPVALLEY OR WEST TO SOUTHWEST WINDS EXPECTED ACROSS MUCH
OF THE RED ROCK WILDFIRE COMPLEX. A WEAK SYSTEM WILL SKIRT WESTERN
WYOMING THIS WEEKEND. THIS WILL RESULT IN A SLIGHT CHANCE FOR SOME
HIGH BASED RAIN SHOWERS SATURDAY...WITH A LITTLE BETTER CHANCE OF
SEEING A SHOWER OR EVEN A THUNDERSTORM SUNDAY. HOWEVER...A WETTING
RAIN IS UNLIKELY. THE MAIN HAZARD WITH THIS ACTIVITY WILL BE GUSTY
AND ERRATIC WINDS. A MAJOR CHANGE IN THE WEATHER WILL
OCCUR...MIDDLE TO LATE NEXT WEEK AS A STRONG STORM SYSTEM MOVES
ACROSS THE REGION. ACCUMULATING SNOW WILL BE POSSIBLE WITH THIS
SYSTEM...ESPECIALLY AT THE HIGHER ELEVATIONS OF THIS FIRE COMPLEX.

...THUNDERSTORMS IMPLY STRONG GUSTY AND ERRATIC WINDS...
...HAINES INDEX IS HIGH LEVEL HAINES BOTH DAY AND NIGHT...
