Marine Weather and Tide Forecast for Whittier, AK

.SHORT TERM FORECAST SOUTHWEST ALASKA AND THE BERING SEA/ALEUTIANS (Days 1 through 3)...

Conditions over Southwest Alaska continue to calm down as the main band of snow near the Kuskokwim River and the northern Bristol Bay starts to diminish. Widespread chances for snow will end by midday for Southwest, with the exception of places along the Aleutian and Alaska Ranges. The broad upper low in the Gulf of Alaska will continue to send cold air southward over the Bering, resulting in many locations along the eastern Aleutians and Pribilof Islands still experiencing gusty conditions. Gale force winds will persist throughout the day Sunday before starting to weaken Sunday night into Monday. The cold air aloft will help support showery activity over most of the eastern Bering, mainly in the form of a rain-snow mix. Additionally, the strong northerly flow will help aid in upslope precipitation for the eastern Aleutians and portions of the Alaska Peninsula, lasting through Monday afternoon.

Looking further out west, the front of a weaker low will move over the western Aleutians Sunday afternoon, producing light precipitation and some gale force gusts. During the day on Monday, a new shortwave will phase with the western Bering low, helping intensify precipitation rates and expanding the wind field along the front of the new system. The low will slowly shift southeastward through Tuesday before locating itself in the North Pacific by the end of the short-term forecast period. As this low moves towards the North Pacific, a ridge of high pressure builds in over most of the Bering, extending eastward towards the Southwest coastline and persisting into midweek.

.LONG TERM FORECAST (Days 4 through 7: Tuesday through Friday)...

On the Alaskan Upper level weather map, a closed low over the Southcentral Gulf of Alaska with its gusty winds and rainfall continues to weaken as it slides towards Queen Victoria Island for Thursday. A second closed low center, the remnants of Tropical Storm Barijat is located South of the Western Aleutians drifting Eastward to the South of the Alaska Peninsula for the end of the workweek. This low links up with a positively tilted trough extending from the Arctic over the Canadian Border before curving to the low center. Gusty winds and locally moderate rainfall with the associated surface low spread across from the Western to the Eastern Aleutians through late Wednesday, diminishing. The leading edges of this low develop moderate rainfall to the South of Kodiak Island by Friday. An upper level ridge over the Northern Bering expands to cover most of the Bering through Friday.

PANC...Southeasterly low-level windshear should subside later this morning when down-inlet flow becomes stronger and more dominant. Otherwise, expect mainly light northerly winds and VFR conditions to be maintained through the TAF period. Some showers could make it over the mountains today, but southeast flow aloft should keep the area mostly dry with most precipitation remaining confined south and east at the coast.
