Alaska Minor Flood Advisory | Effective 09/15/2026 08:31

* WHAT...Flooding caused by onshore flow restricting Kuskokwim River drainage in combination with excessive rainfall is expected. * WHERE...Kuskokwim near Bethel. * WHEN...Until 400 PM AKDT Tuesday. * IMPACTS...Minor flooding in low-lying and poor drainage areas. River or stream flows are elevated. Ponding of water in areas is occurring or is imminent. * ADDITIONAL DETAILS... - At 715 AM AKDT, river gauges in Bethel have detected a rise in water level above 8.5 feet. River gauge reports indicate rises in water levels from the Kuskokwim River back-up in combination with heavy rain across the advisory area. This is causing minor flooding from overflow of poor drainage areas, especially along the Kuskokwim. - Strong onshore winds along the Kuskokwim coast have limited the ability for the Kuskokwim River to drain out into the Bering Sea. This has caused rapid river rises along the coast and inland into Bethel. Water levels are expected to back up along Brown Slough and flood low lying areas of Bethel and areas along the Kuskokwim. - For Kuskokwim River at Bethel: At 6:50am the stage was 8.6 feet. Flood Stage is 8.5 feet. Impacts: At 7.0 feet: Action and bankfull stage. At 8.5 feet: Minor flood stage. Water starts to back up along Brown Slough and flood low lying areas. At 12.0 feet: Moderate flood stage. At 14.0 feet: Major flood stage. - Http://www.weather.gov/safety/flood
