Gale Warning 594, NWS Anchorage, AK

SOUTHCENTRAL AND SOUTHWEST ALASKA FORECAST DISCUSSION
NATIONAL WEATHER SERVICE ANCHORAGE AK
400 PM AKDT SAT SEP 21 2013

.MODEL DISCUSSION...RATHER GOOD IN THE NEAR TERM THEN THEY GET WORSE
OUT INTO THE EXTENDED PERIOD. GFS HAS A GOOD FIX ON THE STORM
CURRENTLY MOVING INTO THE GULF OF ALASKA TODAY.

965 LOW SLOWING AS IT MOVES EASTWARD ACROSS THE GULF AND BECOMES
STATIONARY ABOUT 180 MILES SOUTHWEST OF YAKUTAT SUNDAY AFTERNOON WITH
A SLIGHTLY HIGHER CENTRAL PRESSURE OF 970 MB. NORTHWEST WINDS WILL
CONTINUE TO INCREASE ACROSS KODIAK ISLAND FOR THE REMAINDER OF THE
AFTERNOON AND CONTINUE THROUGH TONIGHT WITH POSSIBLE GUSTS OF 50+ MPH
AT THE STATE AIRPORT. UPPER TROF SWINGING SOUTHEAST ACROSS BRISTOL
BAY PROVIDES THE BEST UPPER SUPPORT TO THE WINDS OUT ACROSS THE
ALASKA PENINSULA, AND MAYBE THE EASTERN ALEUTIANS. HIGH WIND WARNING
FOR TONIGHT OVER THE ALASKA PENINSULA WAS CANCELED AS THIS TROUGH NO
LONGER LOOKS STRONG ENOUGH TO GENERATE WARNING LEVEL WINDS. BY MIDDAY
SUNDAY WINDS WILL NOTICEABLY DIMINISH ALL AREAS BUT REMAIN QUITE
GUSTY KODIAK ISLAND ZONES AND THE CHANNELED AREAS OF SOUTHCENTRAL
ALASKA AND PRINCE WILLIAM SOUND.

UPSTREAM LOW NOW OVER THE WESTERN BERING IS COMPARATIVELY WEAK WITH
THE MAIN LOW CENTER STAYING WEST OF 180. THE ASSOCIATED FRONT WILL
SPREAD SOME LIGHT RAIN AND FOG TO THE PRIBILOFS AND UNALASKA AREAS
SUNDAY AFTERNOON AND EXTEND BACK SOUTHWEST ACROSS ADAK AND ATKA.
WINDS WITH THE FRONT WILL BE IN THE 15 TO 25 MPH RANGE.

ON MONDAY ANOTHER STORM RAPIDLY DEVELOPS AND MOVES NORTHEAST TO ATKA
MONDAY EVENING. THE TRACK OF THIS STORM WILL BE NEAR OR FATHER NORTH
THAN THE ONE NOW IN THE GULF OF ALASKA. GALE AND POSSIBLE STORM FORCE
WINDS WITH HEAVIER RAIN WILL PUSH ACROSS THE PENINSULA AND BRISTOL
BAY
TUESDAY AND KODIAK ISLAND TUESDAY NIGHT. LOW CENTER MOVES INTO THE
WESTERN GULF WEDNESDAY EVENING AS HIGH PRESSURE BUILDS IN BEHIND
ACROSS THE EASTERN BERING.
