NWS Anchorage, AK wrote its last area forecast discussion before this gale warning went out at Sep 27, 4:00 PM AKDT, 12 hours earlier.

AREA FORECAST DISCUSSION
SOUTHCENTRAL AND SOUTHWEST ALASKA
400 PM AKDT MON SEP 27 2010

.MODEL DISCUSSION...MODELS ARE IN GOOD AGREEMENT THROUGH THE FIRST
THREE DAYS. MODELS ARE NOT DIVERGING SIGNIFICANTLY BY THE WEEKEND
PERIOD WHICH WILL HAVE A LARGE IMPACT ON THE GULF OF ALASKA REGION.
AT THIS TIME THE SHORT TERM HAS A MIX OF NAM AND GFS WHILE THERE IS A
LEANING TOWARD THE ECMWF FOR LATER PERIODS.

.ANALYSIS AND UPPER LEVELS...THIS AREA OF THE HEMISPHERE IS BEING
DOMINATED BY A LARGE UPPER LEVEL LOW CENTERED JUST OFF THE ARCTIC
COAST. UPPER LEVEL TROUGHS EXTEND OUT OF THIS LOW DIGGING SOUTHWARD
JUST EAST OF THE AL-CAN BORDER AND WELL AS INTO THE CENTRAL BERING
SEA. THE JET STREAM AT 250 MB MOVES OFF JAPAN TO THE CENTRAL ALEUTIAN
ISLANDS BEFORE WEAKENING IN THE GULF OF ALASKA.
AT THE SURFACE THERE ARE TWO SIGNIFICANT LOWS WITH A HIGH SITUATED
OVER THE VERY MIDDLE ON THE STATE.
THE LOW IN THE EASTERN GULF IS WEAKENING AND MOVING EASTWARD AND IS
NO LONGER A SIGNIFICANT WEATHER FACTOR IN SOUTHERN ALASKA. THE STRONG
STORM IN THE BERING SEA IS THE REMNANTS OF TYPHOON MALAKAS. THIS
POTENT SYSTEM WILL CROSS THE ALASKA PENINSULA NEAR FALSE PASS AND
THEN MOVE INTO THE GULF OF ALASKA BY WEDNESDAY.

.SHORT TERM FORECAST...THE BERING SEA SYSTEM IS BRINGING HIGH WINDS
TO THE CENTRAL ALEUTIANS WITH THE ADAK AREA GUSTING OVER 75 MPH THIS
AFTERNOON. THIS SYSTEM IS BRINGING RAIN TO THE BERING SEA REGION AND
THE PRECIPITATION TYPE WILL STAY RAIN WITH AS THIS IS AN OLD TROPICAL
SYSTEM.

THE PATTERN OF A COLD UPPER LEVEL LOW WITH SURFACE HIGH IS CONDUCIVE
FOR CLEAR BUT CHILLY WEATHER...WHICH IS WHAT IS OCCURRING OVER A
LARGE PART OF MAINLAND ALASKA TODAY. AN EXCEPTION TO THIS IS THE
EASTERN COPPER RIVER BASIN WHERE THERE IS STILL SOME LIGHT SNOW
FALLING...BUT THIS SHOULD END BY THIS EVENING. WITH THE BERING SEA
SYSTEM MOVING INTO SOUTH CENTRAL ALASKA CLOUDS WILL MOVE BACK INTO
SOUTHERN ALASKA OVERNIGHT.

.LONG TERM FORECAST...MODELS ARE A BIT UNDECIDED AS THE WEEKEND
APPROACHES BUT THE MEAN TROUGH AXIS WILL REMAIN OVER WESTERN ALASKA
AND THE EASTERN BERING SEA THROUGH THE WEEKEND WHICH DOES KEEP MOST
OF THE AREA IN CYCLONIC FLOW SO THE LONG STRETCH OF SUNNY AND CLEAR
WEATHER IN SOUTHERN ALASKA APPEARS TO BE COMING TO A RAPID END.

.AER/ALU...WATCH/WARNING SUMMARY
PUBLIC...HIGH WIND WARNING 187.
MARINE...STORM 170 172 175 176.
         GALE 130 150 155 160 165 171 179 180 185.
FIRE WEATHER...NONE.
