Special Weather Statement
A pattern change begins Tuesday as clear and cold conditions give way to accumulating snow for the panhandle by the middle of the week as a system moves in from the northern Gulf. Current expectation is snow will be slow to accumulate, with this event proving to be longer in duration with forecast accumulations around 4 to 8 inches of snow starting Tuesday through Thursday. Highest snowfall totals will be for areas north of Sumner Strait, though a brief period of warming conditions late Tuesday will see some areas of the central panhandle change over to rain briefly, before cooler air returns through Wednesday. Thursday will see snow showers become increasingly predominant, with highly variable snow accumulations expected as the low moves south. Stay tuned for latest forecast updates at weather.gov/juneau
Winter Weather Advisory
...ACCUMULATING SNOW ACROSS THE PANHANDLE TO END THE WEEK... .A front moving across the gulf and developing low across the northern coast will bring snow showers to the panhandle beginning late Wednesday night. With stable cold dry continental air in place ahead of this system, precipitation is expected to remain snow throughout the event with high snow ratios. The initial frontal wave will push eastward into the panhandle with the northeast gulf coast seeing showers late tonight and highest snow accumulations expected along the outer coast with orographic enhancement. For most areas, snow is expected to be light and fluffy in nature due to cold temperatures both aloft and down to the surface. * WHAT...Snow expected. Total snow accumulations of 4 to 8 inches. * WHERE...Glacier Bay, Eastern Chichagof Island and Admiralty Island. * WHEN...Until 3 AM AKST Friday. * IMPACTS...Travel could be very difficult. * ADDITIONAL DETAILS...Snow showers will begin to impact communities along Icy Strait and Admiralty Island early Thursday. Heavier snow showers will likely develop further inland Thursday evening as the low tracks southward along the outer coast and a deformation band sets up.

Winter Weather Advisory
An atmospheric river will be impacting the area starting early Friday morning. Temperatures are expected to be slow to warm around Haines and Skagway Friday; possibly not warming above freezing until Friday evening near sea level when southerly winds with gusts to 50 mph could develop during the transition to rain. Inland and higher elevation areas of the Haines and Klondike highways, specifically above 1000 ft, could remain snow through the entire event. For the Icy Strait corridor, continued snow showers followed by warm, moist air overrunning the arctic boundary south of the area will bring accumulating snow. * WHAT...Snow. Additional snow accumulations of around 3 to 5 inches. * WHERE...Glacier Bay, Eastern Chichagof Island, Cape Fairweather to Lisianski Strait, & City & Borough of Juneau. * WHEN...Until 9 AM AKST Friday. * IMPACTS...Travel could be very difficult. Heavy wet snow will be difficult to manage due to high water content. * ADDITIONAL DETAILS...Snow will be dependent on how strong warm air aloft moves into the area. If warm air moves in quicker, bringing temperatures up faster, then less snow will accumulate and the transition to rain will be faster. If the warm air takes longer to move in, & the rain transition to be slower, total snow accumulations could be up to 8 inches.
Flood Watch
An atmospheric river with multiple surges of moisture is expected to arrive across the panhandle starting late Thursday night and lasting through early Saturday morning. Precipitation is expected to start as snow for many areas, but will be transitioning to rain for area near sea level up to around Icy Strait and Juneau into Friday morning and at the latest overnight Friday into Saturday for the far northern inner channels of the panhandle. Southern panhandle is expected to switch over first Thursday night, Icy Strait during the morning hours of Friday, and Friday evening at the latest for Haines and Skagway. With the transition, snow levels are expected to rapidly increase to 2500 ft or greater in the southern half of the panhandle. For Haines and Skagway, it is possible to only reach around 1000 ft. Total rainfall amounts from late Thursday night through Friday night may range around 3.0 to 4.5 inches extreme southern panhandle, including Ketchikan and Metlakatla, 2.0-3.5 inches for the central inner channels including Petersburg, Wrangell, and Kake, 2.0 to 3.5 inches for the Icy Strait corridor including Juneau, and 1.0 to 1.5 inches for the far northern inner channels near sea level. Furthermore, any snowfall accumulations on areas cleared of the deep snow pack, such as sidewalks or roadways, may cause additional runoff from melting snow. Currently expecting the snowpack to absorb most rainfall from this weekend system and produce minimal runoff in the northern half of the panhandle with a deep sea level snowpack. Therefore, snow, ice, or other debris could potentially blocking storm drains and allow for ponding of rain and snowmelt in areas that they normally would not collect, such as roadways. Rain for sea level areas is expected to continue into the weekend, with a series of fronts to push more moisture over the area. Early indication of an additional 1.5-2.5 inches of rain for the southern panhandle, 1.0 to 2.0 inches for the central panhandle and Icy Strait, and up to 1.5 inches of rain near Haines and Skagway. Details for how this will interact with the existing snowpack and when it will be primed and begin to runoff is still unknown at this time. Stay tuned for more information. * WHAT...Flooding caused by rain and snowmelt continues to be possible. * WHERE...The following areas, Prince of Wales, Eastern Gulf Coast, Southern Inner Channels and Central Inner Channels. This includes the cities of Sitka, Petersburg, Kake, Port Alexander, Craig, Klawock, Hydaburg, Coffman Cove, Thorne Bay, Wrangell, Ketchikan, Hyder, And Metlakatla. * WHEN...From Friday morning through Saturday evening. * IMPACTS...Excessive runoff may result in flooding of rivers, creeks, streams, other low-lying areas and flood-prone locations. Storm drains and ditches may become clogged with debris or snow. Increased risk of possible isolated landslides. * ADDITIONAL DETAILS... - An atmospheric river is forecast to impact the panhandle late Thursday night into Friday night. The Southern and Central panhandle may start out as snow, but is expected to switch to rain late Thursday night. Around 2 to 4.5 inches with possibly locally higher amounts, particularly near Ketchikan and Metlakatla, of rain is across the central and southern panhandle Thursday night through Friday night. An additional 1.0 to 2.0 inches of rain for the central panhandle and 1.5 to 2.5 for the extreme southern panhandle is possible on Saturday. Areas with a preexisting snowpack, both from recent accumulations as well as the deep, previous snowpack, may have additional runoff. Gusty winds at sea level ranging from 40 to 60 mph are likely along the southern panhandle through Friday night. This combination of weather hazards could lead to possible isolated landslides along steep slopes. Conditions for the possibility of flooding and possible isolated landslides will be maximize Friday evening and decrease by Saturday morning. Stream flows in rivers may quickly rise and may exceed flood levels. This atmospheric river has the possibility to extend through the weekend with additional rainfall Sunday.

Hydrologic Outlook
ESFAJK Off and on showers will continue through mid week. The next organized system will push an atmospheric river into the panhandle late Thursday night through Friday. This system will bringing rounds of moderate to heavy rain for communities along and south of a line from Sitka to Angoon to Petersburg. Current forecast rainfall amounts are around 2 to 4 inches, with locally higher amounts approaching 5 inches at higher terrain. This rainfall in combination with rapidly rising freezing levels around 3000 to 5000ft will lead to localized flooding concerns like rapid river rises on small streams, ponding on road ways and poor drainage due to snow blocking drains. Any existing snowpack will become more dense and hard to move. Preparations should begin for an expected rain on snow event going into the weekend. Including the cities of Sitka, Angoon, Petersburg, Kake, Port Alexander, Craig, Klawock, Hydaburg, Coffman Cove, Thorne Bay, Wrangell, Ketchikan, Hyder, and Metlakatla
Winter Storm Warning
...HEAVY SNOW CONTINUES FOR SOUTHEAST ALASKA THROUGH MONDAY... Snowfall is ongoing across much of the panhandle as a front pushes inland, with snowfall rates beginning to diminish in the wake of the front as snow showers replace the previously widespread snowfall. Heaviest snowfall rates will continue through Monday afternoon for locations along and north of the Icy Strait Corridor. An initial warmup moving up from the south has brought temperatures as far north as Hoonah and Pelican to 34 degrees. That warm up is expected to continue into the early morning hours of Tuesday, resulting in some locations changing over to a rain and rain/snow mix for areas along and south of the Icy Strait Corridor from Elfin Cove to Gustavus and Juneau. However, weakening winds combined with heavy snow showers on Tuesday will likely see a switch back to snow for most areas. Main forecast challenge on Tuesday will be the highly variable snowfall accumulations across the northern panhandle due to the hit or miss nature of the showers. The potential exists that warnings and advisories could be extended into Tuesday. * WHAT...Heavy snow. Additional snow accumulations of 1 to 4 inches. Winds gusting as high as 30 mph. * WHERE...Glacier Bay, Eastern Chichagof Island, Cape Fairweather to Lisianski Strait and Admiralty Island. * WHEN...Until 9 PM AKST this evening. * IMPACTS...Travel by land, sea, and air will be be very difficult. Gusty winds could bring down tree branches. * ADDITIONAL DETAILS...Through the afternoon and evening hours, a transition to a rain/snow mix, or even rain, is expected as a strong push of southerly winds moves northward. The southerly winds diminish in strength on Tuesday, allowing snow showers to return to the area.
Winter Storm Warning
...HEAVY SNOW RETURNS TO SOUTHEAST ALASKA ON MONDAY... .Prefrontal showers associated with a weak wave moved through the Icy Strait corridor and western Baranof Island has prompted the winter storm warning to be moved up in time. Snow ratios are very high, pushing greater than 30:1, therefore snow characteristic is very fluffy and dry with very little moisture. Once snow becomes increasingly wet, expect to see any snow depth gained from these snow showers reduced. Therefore, there is very little change in overall snow totals. A weather system will arrive late Sunday night and sweep into southeast Alaska, bringing heavy snowfall across the region on Monday. Heaviest snowfall rates are expected through Monday morning and into the afternoon. An initial warmup moving up from the south is expected through the afternoon and overnight hours on Monday, resulting in some locations changing over to a rain and rain/snow mix for areas along and south of the Icy Strait Corridor from Elfin Cove to Gustavus and Juneau.

Special Weather Statement
While periodic snow showers are falling across portions of the panhandle Friday and "clear and cold" conditions are expected through this weekend, forecasters are monitoring the increasing potential for heavy snow Monday into Tuesday. There is moderate confidence in the timing of the snow to move in from the west Monday morning, spreading inland through the day. Confidence is increasing on a period of heavy snowfall rates with at least 6 inches of accumulation and some potential for locations to see greater than 12 inches. These details on higher snow amounts and where that will fall will be refined in the coming days, so stay tuned for later forecasts and updates as more data becomes available. Locations across the northern panhandle that already have a significant snowpack, now is the time to take mitigation efforts to prepare for this incoming event. This includes: removing snow from vessels, roofs, shelters and out buildings susceptible to collapse, pushing snow banks back, and shoveling around mail boxes and community fire hydrants. Additionally, avalanche risk remains elevated in much of the region.
