NWAC WEATHER STATIONS IN THE CASCADES HAVE RECORDED ABOUT 3 TO OVER 
9 INCHES OF WATER EQUIVALENT IN JUNE. SNOW LEVELS HAVE GENERALLY 
BEEN IN THE 6 TO 8000 RANGE. THIS WEATHER IS LIKELY TO HAVE PRODUCED 
UP TO SEVERAL FEET OF SNOWFALL AT HIGHER ELEVATIONS. TEMPERATURES 
SHOULD BE THE WARMEST BY FAR SINCE LAST SUMMER IN THE OLYMPICS AND 
CASCADES THIS WEEKEND. THIS DRAMATIC WARMING AND RECENT HEAVY SNOW 
ARE THE INGREDIENTS FOR DANGEROUS AVALANCHE CONDITIONS AT HIGHER 
ELEVATIONS ESPECIALLY ON THE VOLCANOES. A SPECIAL CONDITIONS 
STATEMENT HAS BEEN ISSUED BY THE NW WEATHER AND AVALANCHE CENTER.
THIS STATEMENT WILL BE UPDATED AS CONDITIONS WARRANT. PLEASE VISIT 
NWAC.US FOR DETAILS.
