Marine Weather and Tide Forecast for Beluga, AK

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

The forecast remains on track, with some minor adjustments to timing and positioning of key features. The low near the Alaska Peninsula will produce the most impactful weather the next couple days. The strong front associated with this the low will stall over Bristol Bay through Thursday. Expect widespread strong and gusty easterly winds for nearly all of the Bristol Bay region today, as well as gusty winds through the bays and passes of the Alaska Peninsula. Downslope flow will limit rainfall from King Salmon northward, with the bulk of rain falling further south of King Salmon along the Alaska Peninsula as well as north and west of Dillingham. Strong and gusty gap winds are also expected on the back side of the low along the southern Alaska Peninsula (False Pass, Cold Bay, and King Cove). As downslope winds diminish Wednesday night and Thursday, areas of light rain will spread across most of the Bristol Bay region. Meanwhile, drier and warmer conditions will prevail for the Kuskokwim Delta and Kuskokwim Valley the next couple days, though with considerable cloud cover.
Conditions will be fairly quiet over the Bering Sea and Aleutians with just some showers as the low over the central Bering tracks southward to the Aleutians on Thursday before dissipating. By Friday, the only feature left will be a weak low in the eastern Bering Sea, with overall quiet weather region-wide.

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

A broad upper level low over Southern Alaska with multiple troughs and shortwaves rotating through the pattern carries the forecast period. The pattern smooths out with an elongated trough from the Central Aleutians to Southeast Alaska by Tuesday. Most of the active weather is initially expected across the Aleutians and Alaska Peninsula and spreads into and across Kodiak Island and the Gulf of Alaska through Tuesday. Forecast models are in decent agreement with the larger scale features, leaving the smaller surface details in greatest uncertainty.

A weak front spreads rain from the Eastern Aleutians into the AKPEN Saturday. A well developed low and front approaches from the North Pacific for Sunday, and brings more rain from the Eastern Aleutians across Southcentral Alaska through Tuesday. In the West, a developing low and front out of Kamchatka pushes rain into the Western Aleutians and Bering Saturday, and continues along the Aleutians through late Monday. Another strong North Pacific low and front approaches the Western Aleutians and Bering for Tuesday.
