An atmospheric river with multiple surges of moisture has started to push into the panhandle as of early Friday morning and is expected to continue through Friday, lasting into 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. As of 4am Friday, the southern panhandle has begun to swap over to rain. Moving northward, the Icy Strait changeover is expected during the morning hours of Friday, and Friday evening at the latest for Haines and Skagway. With this transition, snow levels are expected to rapidly increase to 2500 ft or greater in the southern half of the panhandle through Friday. 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, Eastern Gulf Coast and Central Inner Channels. This includes the cities of Gustavus, Hoonah, Tenakee Springs, Elfin Cove, Pelican, Angoon, And Juneau. * WHEN...From 9 AM AKST this morning through Saturday evening. * IMPACTS...Storm drains and ditches are clogged with snow that may cause ponding of water in these poor drainage areas. * ADDITIONAL DETAILS... - An atmospheric river is forecast to impact the panhandle through Friday night. Areas around Icy Strait and Juneau will see 3 to 6 inches of snowfall before a transition to rain is expected Friday morning. Heavy rain will fall on the existing snowpack which may lead to increased runoff and may produce ponding of water in poor drainage areas during the watch time frame. Around 1-3 inches of rainfall is possible Friday into Friday night, with another 1-2 inches of rainfall on Saturday.

You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding should be prepared to take action should flooding develop. Flooding may occur in poor drainage areas. Storm drains should be kept clear of debris as much as possible. Stay tuned to further developments by listening to your local radio, television, or NOAA Weather Radio for further information.

An atmospheric river with multiple surges of moisture have moved into the panhandle and is possible to last into Sunday evening. Precipitation has mostly transitioned to rain around Icy Strait and Juneau, and is still expected to transition for the northern inner channels Friday evening into overnight Friday. Snow levels have begun to rapidly increase to 2500 ft around the Icy Strait and Juneau area, with snow levels exceeding 4000 ft in the southern half of the panhandle. A brief, distinct lull in heavy rainfall is now expected overnight tonight into Saturday morning for the southern half of the panhandle, before another surge of moderate to heavy rain. Total additional rainfall amounts from late Thursday night through Saturday night (roughly 48 hours) may range around 4.0 to 5.5 inches extreme southern panhandle, including Ketchikan and Metlakatla, 2.0-3.0 inches for the central inner channels including Petersburg, Wrangell, and Kake, 1.0 to 2.0 inches for the Icy Strait corridor, 2.0 to 3.5 for the Juneau area, 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 or walkways. Another surge of moisture is looking increasingly likely for the southern half of the panhandle overnight Saturday and continuing through Sunday, and therefore, the flood watch was extended. There is growing confidence that very strong rain rates during the morning hours for the Ketchikan, Metlakatla, and Prince of Wales Island, with around a 40-60% chance for 3 hour rates exceeding 0.4 inches. This surge in precipitation may coincide with another surge of wind gusts, with sea level gusts possibly reaching as high as 50 mph Sunday evening. The southern panhandle could see 1.5 to 3.0 additional inches, the central inner channels could receive 1.0 to 2.0 additional inches, the Icy Strait corridor could receive 0.75 to 1.5 additional inches, and the Juneau area could receive 1.5 to 2.5 additional inches. Stay tuned for more information. * WHAT...Flooding caused by rain and snowmelt continues to be possible. * WHERE...The following areas, Eastern Gulf Coast and Central Inner Channels. This includes the cities of Gustavus, Hoonah, Tenakee Springs, Elfin Cove, Pelican, Angoon, And Juneau. * WHEN...Through Saturday evening. * IMPACTS...Storm drains and ditches are clogged with snow that may cause ponding of water in these poor drainage areas. * ADDITIONAL DETAILS... - The Icy Strait and Juneau area has just switched over to rain with the exception of north past Auke Bay, with areas near Gustavus transitioning soon. Heavy rain will fall on the existing snowpack which may lead to increased runoff and may produce ponding of water in poor drainage areas during the watch time frame. Through Saturday evening, an additional 1.0 to 2.0 inches for the Icy Strait corridor, 2.0 to 3.5 for the Juneau area is possible. Depending on how culverts and storm drains behave during this upcoming rain, along with the additional rainfall of around 0.75 to 2.5 inches with higher amounts near Juneau, the flood watch may be extended into Sunday.
