Alaska Unknown Hydrologic Outlook | Effective 09/10/2026 16:42

ESFAFC UPDATE: Based on forecast winds and water levels, flooding continues to look very unlikely along Kuskokwim River and the coast. However, higher water levels and winds gusting up to 30 to 45 mph may still impact activities along the water. For communities along Kuskokwim River (Tuntutuliak): * Gusty winds and storm surge pushing up the river will likely cause water levels to reach bankfull. * Flooding will be very unlikely as high water currently in McGrath and Crooked Creek is now forecast to arrive in the lower Kuskokwim River after the storm surge has subsided. * Timing: Water levels will be highest during high tide, which will be from around 11 AM through 3 PM on Friday. For communities along the coast (Kongiganak, Kwigillingok, Kipnuk, Toksook Bay, Tununak): * Though there will be gusty onshore winds and storm surge, water levels will very likely remain below 1 to 2 feet above the normal highest tide, with no flooding expected. * Timing: Water levels will be highest during high tide on Friday, from about 10 AM through 2 PM. Communities further north (like Toksook Bay and Tununak) may see higher water levels during Thursday nights high tide as well, from about 10 PM through 2 AM. Next steps: * Use caution along Kuskokwim River and along the coast, and plan for higher than normal water levels. * Send weather or flooding reports to inws.ncep.noaa.gov/report/ or by calling 1-907-266-5127.
