...GLACIER DAMMED LAKE ON THE SNOW RIVER WHICH FLOWS INTO KENAI
LAKE IS RELEASING...

THE SNOW GLACIER DAMMED LAKE HAS RELEASED. WATER LEVELS ON THE
SNOW RIVER ARE CRESTING TUESDAY AFTERNOON AND WILL BEGIN FALLING
OVERNIGHT AND INTO WEDNESDAY. WATER LEVELS ON KENAI LAKE ARE
RISING AND ARE EXPECTED TO CREST EARLY WEDNESDAY AT A STAGE OF
ROUGHLY 10.75 FEET...WHICH IS BELOW ACTION STAGE. SMALLER RISES
ARE EXPECTED ON THE KENAI RIVER TOWARD THE END OF THIS WEEK. NO
FLOODING IS EXPECTED.

A GLACIER DAMMED LAKE RELEASE IS A NATURALLY OCCURRING PROCESS.
IN THE HEADWATERS OF THE SNOW RIVER THE SNOW GLACIER IMPOUNDS A
LAKE. OVER TIME PRECIPITATION AND MELTING GLACIAL ICE CAUSE THE
LAKE LEVEL TO RISE. WHEN THE LAKE IS SUFFICIENTLY FILLED...IT
CAUSES A SMALL PART OF THE GLACIER TO LIFT...THUS DRAINING THE
LAKE. THE SNOW GLACIER DAMMED LAKE TYPICALLY DRAINS EVERY OTHER
FALL.

FORECAST ESTIMATES OF PEAK STAGE AND TIMING WILL BE UPDATED ON THE
ALASKA-PACIFIC RIVER FORECAST CENTER WEBSITE: APRFC.ARH.NOAA.GOV.

...UNSEASONABLY COOL TEMPERATURES REST OF THE WEEK...

AN EARLY AUTUMN LIKE WEATHER SYSTEM WILL BE SETTLING OVER THE
REGION MIDWEEK AND CONTINUE INTO THE LABOR DAY WEEKEND. THIS WILL
LEAD TO UNUSUALLY COOL CONDITIONS THROUGH THIS PERIOD WITH HIGH
TEMPERATURES IN THE COLUMBIA BASIN IN THE 60S TO LOWER 70S WHILE
THE MOUNTAINS WILL SEE 50S AND 60S. OVERNIGHT LOW TEMPERATURES
WILL ALSO BE COOL WITH 40S IN THE BASIN AND UPPER 20S AND 30S IN
THE MOUNTAINS.

THE INITIAL COLD FRONT WILL MOVE THROUGH THE REGION ON WEDNESDAY
BRINGING A CHANCE OF PRECIPITATION. UNSTABLE CONDITIONS WILL LEAD
TO SOME MORE SHOWERS ON THURSDAY. PERHAPS THE BEST CHANCE FOR A
MORE WIDESPREAD RAIN WOULD COME LATE FRIDAY AND INTO SATURDAY AS
THE HEART OF THE COLD AIR MOVES OVER THE FORECAST AREA. SNOW
LEVELS DURING THIS TIME WILL LOWER TO AROUND 6500 FEET. THIS MEANS
THERE COULD BE A DUSTING OF SNOW IN THE HIGHER ELEVATIONS OF THE
WALLOWA, ELKHORN, STRAWBERRY AND CASCADE MOUNTAINS.

THOSE PLANNING OUTDOOR ADVENTURES SHOULD BE PREPARED FOR THE
COOLER CONDITIONS AND POTENTIAL PRECIPITATION.
