300 PM AKDT THU SEP 4 2008
...FLOOD POTENTIAL...
THE RISK OF FLOODING IS LOW ACROSS THE REST OF THE STATE.  
 
ANALYSIS OF GAGES ON THE ALSEK RIVER SUGGESTS THAT THE TWEEDSMUIR
GLACIER HAS NOT BLOCKED THE RIVER.
...HYDROMETEOROLOGICAL CONDITIONS...
A LOW OVER SOUTHWEST ALASKA SPREAD CLOUDS AND RAIN ACROSS THE
SOUTHERN MAINLAND AND ACROSS THE GULF COAST AND PANHANDLE. PORTAGE
AND NUCHEK ON HINCHINBROOK ISLAND REPORTED OVER 2 INCHES OF RAIN ON
WEDNESDAY WHILE 1 TO 2 INCHES OF RAIN FELL ALONG THE WESTERN KENAI
PENINSULA AND EASTERN PRINCE WILLIAM SOUND. A POCKET OF A HALF TO
THREE QUARTERS OF AN INCH FELL OVER THE WINDWARD SIDE OF THE UPPER
ALEUTIAN RANGE. LIGHTER AMOUNTS WERE RECORDED OVER THE SOUTHEAST.  
SEVERAL SHORT WAVES MIXED INTO THE MEAN TROUGH OVER THE STATE WILL
HELP TO KEEP THE WEATHER UNSTABLE SHOWERY OVER SOUTHERN ALASKA.
CONTINUED MOIST ONSHORE FLOW LEAVES THE PANHANDLE WITH ADDITIONAL
SHOWERS AS WELL. MUCH THE SAME PATTERN REMAINS ON FRIDAY WITH THE
NEXT MAJOR LOW SWEEPING INTO THE CENTRAL ALEUTIANS SATURDAY NIGHT.  
...FREEZING LEVELS... 
FREEZING LEVELS THURSDAY MORNING WERE THE HIGHEST OVER THE
MID-SECTION AND SOUTHEAST WHERE ELEVATIONS WERE BETWEEN 6500 FT AT
FAIRBANKS AND 7800 FT AT ANNETTE. BELOW NORMAL VALUES OVER SOUTHWEST
