An atmospheric river with multiple surges of moisture has moved into the panhandle and will continue through Sunday evening. Heavy rain rates during the morning hours for Ketchikan, Metlakatla, and Prince of Wales Island are expected to continue, with around a 40-60% chance for 3 hour rates exceeding 0.4 inches. This surge in precipitation will coincide with another surge of wind gusts, with sea level gusts possibly reaching as high as 50 mph through Sunday morning. The southern panhandle could see 2.0 to 3.5 additional inches of rainfall, while the central inner channels could receive 1.0 to 2.0 additional inches. * 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 Petersburg, Kake, Port Alexander, Craig, Klawock, Hydaburg, Coffman Cove, Thorne Bay, Wrangell, Ketchikan, Hyder, And Metlakatla. * WHEN...Through Monday morning. * 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. * ADDITIONAL DETAILS... - Around 3.5 to 7.5 inches of rain has fallen for Prince of Wales, Ketchikan, and Metlakatla and around 2.5 to 4.0 inches has fallen for Petersburg and Wrangell within the last 48 hours. Forecast rainfall amounts for Sunday are around 1.0 to 2.0 inches for the central panhandle, along a line from Sitka to Petersburg. Further south, around 2.0 to 3.5 inches of rainfall is expected for Prince of Wales Island, Annette Island, and the Ketchikan Gateway Borough, with locally higher amounts expected at higher terrain. Areas with a pre-existing snowpack, both from recent accumulations as well as the deep, previous snowpack, may have additional runoff. Small streams and rivers are falling, but are expected to rise again through Sunday. There is continued uncertainty for exceedence of flood stage based on how the snowpack at upper elevations will respond to the incoming rain. Ward Creek above Lake Connell Dam is currently experiencing minor flooding. Otherwise, current forecast reflects these rivers saying within their banks, however, uncertainty in snowpack depth, temperature, and runoff potential could lead to minor flooding. This combination of weather hazards could lead to possible isolated landslides along steep slopes. Conditions for the possibility of flooding and possible isolated landslides going forward will be maximized through Sunday morning as the heaviest rates and wind gusts up to 50 mph at sea level.
