What forecasters said that day
The local office's own words before this gale warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.
NWS Anchorage, AK wrote its last area forecast discussion before this gale warning went out at Mar 10, 4:26 AM AKST, 10 hours 53 minutes earlier.
Area forecast discussion, Mar 10, 4:26 AM AKST, 10 hours 53 minutes before
Southcentral and Southwest Alaska Forecast Discussion National Weather Service Anchorage AK 426 AM AKST Sat Mar 10 2018 .ANALYSIS AND UPPER LEVELS... A broad longwave trough extends through mainland Alaska and the western Gulf. This setup is bringing southerly flow and showers to the north Gulf coast. Out west, ridging has built in over the western Bering bringing warm air from the south with it. && .MODEL DISCUSSION... The models continue to struggle in this active pattern. This is particularly true for the east side with multiple lows moving through the Gulf. So while there is high confidence with an active pattern bringing multiple lows through the area, there is uncertainty with how the lows will move through and the impacts they may have. && .AVIATION... PANC...VFR conditions and light winds will persist. && .SHORT TERM FORECAST SOUTHCENTRAL ALASKA (Days 1 and 2)... Snow showers...some heavy...will persist over the eastern Kenai Peninsula today, but be gradually tapering off during the evening. The Winter Storm Warning has been cancelled. Due to backcountry avalanche danger through the weekend, a Special Weather Statement to relay information from The Chugach National Forest Avalanche Center has been issued. The rest of the north Gulf coast will continue to see snow showers today and the showers will also taper off by tonight. Most of the remainder of Southcentral will just see a few snow showers spill over the mountains but POPs are generally low inland. The next weather system to watch is expected to move into eastern Prince William Sound Sunday and spread westward Sunday night. Model tracks are still a bit uncertain but the Prince William Sounds region will likely see some more snow with the heaviest amounts being in the eastern Sound this time. && .SHORT TERM FORECAST SOUTHWEST ALASKA (Days 1 and 2)... Winds continue to weaken this morning as the pressure gradient weakens, due to the main storm system having reformed further south in the Gulf due to jet stream energy diving into the trough while deepening it further, causing a further south low position. With this in mind, the blowing snow advisory for the Kuskokwim Delta has expired. Brief ridging will cross the area tonight into tomorrow morning. As the ridge axis passes overhead, weak warm advection will help steepen a low-level inversion, aided by the recent snowfall. This should promote a fairly expansive stratus deck with some fog developing. Our attention then turns to a fast approaching front for the day Sunday. Southeasterly winds will increase ahead of the front, mainly near the coast and at higher elevations. This could promote some areas of blowing snow. However, with the recent snow having compacted some and typically southeast winds bring a wetter snowflake production, how much blowing snow will develop remains questionable enough not to include in the forecast at this time. As the front crosses the region snowfall coverage will be fairly widespread with bursts of moderate intensity snowfall possible. However, accumulations don't look to be to significant with just a few inches expected. && .SHORT TERM FORECAST BERING SEA/ALEUTIANS (Days 1 and 2)... The snow shower activity that has plagued the eastern two thirds of the Bering and Aleutians the past few days will continue to diminish through the morning, as a fast-moving narrow ridge of high pressure builds across the region, moving from its current position across the western central portions of the Bering/chain to the coast of southwest Alaska by tomorrow morning. Quickly following on its heals will be a cold front currently entering the western portions of the region. As it moves from west to east, a deepening low off the Siberian coast will increase warm advection ahead of the incoming front, with a warm front surging through the Aleutians into the north central portions of the Bering. This will allow precipitation to change from snow to rain following the warm frontal passage, mainly south and west of a line from Siberia, through the Pribilof Islands, towards Nelson Lagoon. As for the winds ahead of the fronts, some spotty sustained gales may develop along the warm front across the eastern Bering, with the better chance being immediately ahead of the cold front and near the Aleutians from Nikolski westward. Otherwise, winds will remain below gale criteria. After cold frontal passage, colder air filtering back into the region will allow precipitation to become more showery in nature, with snow showers being the predominant precipitation type. && .LONG TERM FORECAST (Days 3 through 7)... The long term forecast begins Monday with a deep but narrow upper level long wave trough bisecting mainland Alaska and extending south to nearly 30N. A surface low will move from the Northern Gulf into the Prince William Sound bringing another round of snow to coastal areas and the mountains, though the inland areas west of the Kenai and Chugach Mountains look to remain mostly snow free as the bulk of the moisture and energy should remain far enough east. A progressive pattern will continue across the region as we head into the middle of next week as a strong westerly jet moves over the Aleutians and pinches off the upper level low well to the south of our area. Temporary ridging will build in over the southern mainland Tuesday and Wednesday morning bringing a short break in the stormy pattern before another trough digs in across the Eastern Bering spinning up another low that looks to move across Western Alaska and eventually Southcentral by Thursday. The models begin to diverge some at this point with the track of the low center but all agree that a decent amount of moisture will be associated with this system aided by a strong southerly upper level jet pumping moisture in from the North Pacific. This storm also looks to be a bit warmer than the previous ones we've seen the past couple of weeks meaning precipitation types could be challenging with rain possibly mixing in with snow at sea level locations. Stay tuned as details become clearer regarding this system next week. && .AFC WATCHES/WARNINGS/ADVISORIES... PUBLIC...None. MARINE...Gales...174 175 176 177 178 351 352.

SPECIAL WEATHER STATEMENT National Weather Service ANCHORAGE AK 237 PM AKST Sat Mar 10 2018 AKZ125-120200- Western Prince William Sound- Including the cities of Whittier, Seward, Girdwood, and Moose Pass 237 PM AKST Sat Mar 10 2018 ...Special Avalanche Bulletin... Bulletin - Immediate Broadcast Requested The following message is transmitted at the request of the Chugach National Forest Avalanche Center - The Chugach National Forest Avalanche Center in Girdwood AK has issued a Special Avalanche Bulletin. * Timing...In effect now through 6 pm Sunday March 11th, 2018. * Affected Areas...For Turnagain Pass and areas in and around Eastern Turnagain Arm, including the Kenai and Western Chugach Mountains. * Avalanche Danger...Dangerous avalanche conditions will exist through the weekend due to 2-4 feet of snow that has fallen on an unstable base. Human triggered large avalanches are likely on slopes steeper than 30 degrees. Precautionary/Preparedness Actions... Choose terrain that is flat or less than 30 degrees in steepness, with nothing steeper above you. If skies clear for travel into the alpine elevations, careful snowpack evaluation, cautious route-finding and conservative decision making skills will be necessary to identify and avoid unstable slopes. Similar avalanche danger may exist at locations outside the coverage area of any avalanche center. Check www.avalanche.org for your closest avalanche center and to learn more about how to learn about how to identify avalanche hazards. This Special Bulletin does not apply to ski areas or highways where avalanche reduction measures are performed.
