Marine Weather and Tide Forecast for Akhiok, AK

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

Conditions have started improving across Southwest Alaska, thus, the Winter Weather Advisories and Blizzard Warnings have come to an end. Gusty winds and lighter snow showers are expected to continue through this morning behind the front, which may result in reduced visibilities at times, but the worst conditions are expected to have finished. Expect gusty winds and snow showers to gradually taper off into this afternoon.

The large low continues rotating in the Bering Sea, currently visible on satellite situated north of Saint Paul. This low will continue to creep to the northwest and towards Nunivak Island, before weakening and moving towards Bristol Bay Friday. Associated warmer air will filter into Southwest Alaska, brining temperatures up into the 20's and 30's, though mostly remaining below freezing.

.LONG TERM FORECAST (Days 4 through 7 - Saturday through Tuesday)...

The persistent upper level ridge looks to remain anchored in the Pacific with several shortwaves rounding the top of the ridge axis for this weekend. A low pressure system and its accompanying front enter the eastern Bering by Saturday before pushing inland across Southwest Alaska and the Alaska Peninsula. The main threat with this system at this time looks to be the potential for moderate to heavy snowfall across much of Southwest Alaska and rainfall across the Alaska Peninsula. Only slight weakening of this system is set to occur as the shortwave further deepens as it tracks across the AKPen before the surface low repositions itself and consolidates in the northern Gulf for Sunday. This brings increased chances for snowfall across Southcentral Sunday with models in fairly good agreement for inland locations to see a round of measurable snow. Gusty northwesterly gap winds are likely along the southern AKPen up through the Barren Islands Sunday into Monday as the pressure gradient tightens between the departing low and a ridge building in the Bering. The low continues towards Southeast Alaska by early next week while the Bering ridge slides east to promote mainly dry conditions across Southern Alaska early next week.

Uncertainty and model spread increases heading into early next week as upstream activity in the western Bering picks up.
Deterministic models continue to struggle with the positioning and phasing of several shortwaves rotating around broad upper level troughing centered over Kamchatka. A series of lows pressure systems and fronts will bring an unsettled pattern with periods of precipitation and elevated winds across the Aleutian Chain through early next week, though exact timing and details will become more clear in the coming days.
