Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 511 PM AKDT Thu Apr 23 2026 .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 through 3/Tonight through Sunday)... Key Points: * Continued unseasonably wet and windy weather through Friday night. * The wettest weather will be the eastern Kenai Peninsula, Prince William Sound, and Susitna Valley. There has been a break in rain for many of these areas this afternoon, but the next round of heavier rain will arrive by this evening. * Additional rainfall through Saturday morning: 2 to 5" along the Gulf and Prince William Sound coastlines (including Seward, Whittier, Valdez and Cordova) 0.50 to 1" over eastern interior Kenai Peninsula; 1 to 2" in the western Susitna Valley; and lighter amounts elsewhere. * A Flood Watch remains in effect for the Susitna Valley from 9pm this evening through Saturday morning. Rain and snowmelt combined with still frozen surfaces could make it hard for all of the water to find a place to properly drain. As a result, there could be minor flooding of low-lying roads and properties. * Strong and gusty southeasterly gap winds will persist through at least Friday afternoon. Locations that will see some of the strongest winds include Turnagain Arm, Anchorage Hillside, south to west Anchorage, Palmer and the Knik River Valley, and Glennallen and the Copper River. A high amplitude pattern remains firmly entrenched over Alaska, with a trough in the Bering Sea/North Pacific and a ridge extending from the northeast Pacific to the Al-Can border. Deep and moist southerly flow is noted in water vapor with a moisture plume streaming northward from around 40N latitude up to the western Gulf. A series of vigorous shortwaves can also be seen in satellite imagery, with the strongest approaching Kodiak Island and the western Gulf this afternoon. At the surface, a weak frontal wave is tracking northward up a stationary front which sits beneath the upper level moisture plume. As these features continue northward, stronger winds and steady rain are spreading across Kodiak and the western Gulf. Meanwhile, there is a brief break in significant rainfall (and mountain snow) over Southcentral, with just some localized light precipitation in upslope areas along the south side of mountain ranges. Otherwise, it is cloudy with gusty southeast winds (especially through the typical coastal gaps) and temperatures in the 40s to around 50. While the expected weather for the next couple days is generally on track, there have been some shifts in model guidance with depiction of individual short-waves which will affect the timing of heaviest precipitation and strongest winds. The short-wave now approaching the western Gulf now looks like the strongest of short-waves with the best moisture transport aloft. It will amplify just a bit as it continues northward across the western half of Southcentral tonight. The heaviest precipitation will be across the southeastern Kenai Peninsula and northern to western Susitna Valley from approximately 9pm this evening through 6am Friday. Southeasterly winds will ramp up once again (ahead of the short-wave), with the strongest winds along Turnagain Arm and affecting the Anchorage Hillside. Winds look a bit stronger than last night, with a few gusts of 60 mph or higher likely for upper Potter Marsh and the upper Hillside of Anchorage. With the ground still largely frozen and trees yet to leaf out, do not expect any significant impacts due to these winds. Another short-wave will cross nearly the same area Friday afternoon through Friday night. Model guidance has trended toward a weaker, less amplified short-wave. As a result, winds and precipitation rates with this short-wave look less impressive and the forecast has been updated to reflect this. The upper level flow will shift behind this short-wave on Saturday as a new storm system moves into the Bering Sea, bringing an end (temporarily) to the deep southerly flow and moisture transport. One final short-wave will cross through Southcentral during the day Saturday, but precipitation with it will be quite light. A short-wave ridge will then briefly move through Saturday night into Sunday morning, with the frontal system from the Bering storm following closely behind. The upper level flow on Sunday will look very similar to what is in place today. Thus, unseasonably wet and windy weather will return late in the weekend and into the new work week. -SEB && .SHORT TERM FORECAST SOUTHWEST ALASKA/BERING SEA/ALEUTIANS (Days 1 through 3: Tonight through Sunday)... Key messages: - A low over the northern Bering Sea will steadily weaken through Friday night. - An unseasonably strong low will rapidly deepen as it approaches the central portions of the Aleutians on Saturday. - Very strong winds could impact much of the Aleutian Chain as the low crosses into the southern Bering Sea on Sunday. Widespread Gale to Storm Force winds could impact much of the marine outlook area this weekend. Discussion: A broad region of cyclonic flow now extends across much of the Bering Sea and Aleutians, with several embedded shortwave troughs rotating around the larger area of low pressure. Two of such disturbances are moving north into Southwest within a belt of southerly flow, ushering a few bands of light rain north across the region. Much of Southwest is still seeing rather blustery conditions as well, with gusty southeast winds persisting around the eastern fringes of a weakening surface low moving over Saint Matthew Island. Things have quieted down for now across most of the Aleutian Chain, where light west winds are prevailing along with occasional rain/snow showers drifting past. From tonight through Friday night, little change in the general pattern is expected as the low moving over the northern Bering Sea steadily weakens and as multiple shortwave troughs continue to move northeast along the AKPen and over Southwest. Multiple rounds of mostly rain will continue to affect much of the AKPen, Bristol Bay and Kuskokwim Delta as these upper waves move across. Generally calm conditions will continue across the Pribilofs and Aleutians, but this will change rather abruptly over the upcoming weekend. On Saturday morning, a North Pacific low will phase strongly with a potent trough approaching from the west and rapidly deepen into a 950-960 mb Hurricane Force low as it approaches Adak and Atka by Saturday afternoon. Model agreement for this system continues to improve, and it now looks likely that the low center will cross over into the southern Bering Sea near or just west of Adak by Saturday evening. A sting jet of intense winds will develop to the south of the low center, and this corridor of strong winds will progress north into the central/eastern parts of the Aleutian Chain by early Sunday morning. Even though the low will reach peak intensity prior to moving into the Bering Sea, this corridor of winds will still be quite intense. Storm Force sustained winds with Hurricane Force gusts will overspread much of the marine waters surrounding the eastern half of the Aleutians, with potential for wind gusts of 60 to 70 mph or stronger to impact Adak, Atka, Nikolski and Unalaska as the low shifts north late Saturday night into Sunday. Seas as high as 40 ft will move in tandem with the corridor of strongest winds south of the Aleutians between Adak and Nikolski Saturday night into Sunday morning. Farther north, the low's leading front will push across the Pribilofs on Saturday night, spreading precipitation initially in the form of snow across the islands along with southeast winds gusting to around 60 mph. Temperatures will likely be hovering at or just above freezing by this point, so this will limit potential for blowing snow. Snow will transition to rain as temperatures continue to warm on Sunday morning, while gusty winds to the east of the low center persist. The front will reach the Southwest Coast Sunday morning, with a similar progression from wet snow to rain expected through the day on Sunday as gusty southeast winds also spread across Southwest along and ahead of the incoming front. Stay tuned for more details as we continue to monitor this unseasonably strong storm system through this weekend. -AS && .LONG TERM FORECAST (Days 4 through 7: Monday through Thursday)... Unsettled weather is expected to persist across much of Alaska into early next week as a North Pacific low moves into the southern Bering. The low will then track northward, passing northwest of the Pribilof islands by Monday while gradually weakening and occluding. Storm force winds are possible across portions of the central Aleutians Sunday into Monday, with widespread gale-force winds otherwise expected across the Aleutians, much of the Bering and Bristol Bay through Tuesday. Coastal impacts remain limited at this time due to the presence of shorefast ice and an extensive ice pack over the eastern Bering. A frontal system associated with this low will move into the Alaska Peninsula and Southwest Alaska Sunday morning, reaching the western Gulf and Kodiak Island by Sunday afternoon and then progressing into Southcentral Alaska Sunday night. This system will bring a steady stream of moisture into southern Alaska, resulting in widespread precipitation as the front advances. The heaviest precipitation is expected across Kodiak Island, along the northern Gulf Coast, and across higher elevations of the Alaska Range due to upslope enhancement from southeasterly flow. In contrast, downsloping effects are likely to limit precipitation across portions of the western Chugach and Kenai Mountains, as well as along the Bering side of the Alaska Peninsula. As the primary low weakens and occludes over the northern Bering, additional shortwave disturbances are expected to rotate around the parent low and move northward into Alaska. Model guidance is in general agreement on a shortwave moving into Southcentral Alaska Monday night into Tuesday, which will support another period of enhanced precipitation, particularly along the northern Gulf Coast and Kodiak Island where southeasterly flow persists. Beyond Tuesday, model solutions begin to diverge with respect to the timing and placement of additional shortwaves. Some guidance brings additional energy into Southwest Alaska Tuesday into Wednesday, while other solutions delay impacts into Southcentral Alaska until midweek. Confidence in the details decreases during this period; however, the overall pattern continues to support a persistent feed of moisture into southern Alaska, especially across Southcentral.

Southeasterly Turnagain Arm winds will continue to impact the terminal this evening and overnight with strongest gusts of between 35 to 45 kts expected from about 7Z to 12Z as a front pushes through the area and winds bend more towards the terminal. However, lighter northerly winds may precede the front as the stronger winds stay over the Arm towards Fire Island allowing for some LLWS concerns this evening. VFR conditions are expected to persist, though any passing showers may drop ceilings below 5,000 ft AGL and briefly drop visibility to MVFR. Downslope flow will continue to keep most showers out of Anchorage, though chances will increase overnight. &&
