High water will begin in low lying areas on the east side of Fort Yukon from the middle to the end of week, with possible flooding developing over the weekend. This will be a slow-onset flood, then slow to recede event. * ADDITIONAL DETAILS... - Breakup is underway on the Porcupine River east of the border with high water levels due to snowmelt from a much wetter than average winter. The Porcupine River below Old Crow (Canada) crested at 53.56 ft on May 19, while the Porcupine River gage closer to the US border had a record crest of 53.57 ft on May 19. This high water will likely reach Fort Yukon by midweek, at which point the Porcupine may cause the Sucker River to back up into low-lying areas on the east side of town, then spread through the swales westward. Based on historic norms, if flooding occurs, expect floodwaters to slowly peak on the weekend, then slowly recede next week. There is potential for this event to be very similar to flooding last year; however water levels on the Yukon River are not nearly as high as last year which could mitigate the situation. - Http://www.weather.gov/aprfc - Please stay tuned to NOAA weather radio or your favorite local weather news source for updates on this situation. - If you live in low lying areas in Fort Yukon stay alert and be prepared to take action. PRECAUTIONARY/PREPAREDNESS ACTIONS... You should monitor later forecasts and be alert for possible Flood Warnings. Those living in areas prone to flooding in Fort Yukon should be prepared to take action should flooding develop. Take action now to move valuables to higher ground that remained dry during last years flooding.

If another ice jam forms, water could rise further and cause flooding in low lying areas. * ADDITIONAL DETAILS... - The ice jam downstream of Pilot Station released around 3:30 pm Sunday afternoon, and the ice started moving at Mountain Village at 4:30 pm Sunday. Water levels at Mountain Village went up approximately 5 feet Sunday night. Water levels remain high at Mountain Village, St Mary`s and Pitkas Point today. If another ice jam forms, the water levels could rise and cause flooding of low lying areas. - Https://www.weather.gov/aprfc PRECAUTIONARY/PREPAREDNESS ACTIONS... Pitkas Point and St. Mary`s residents should continue to monitor river conditions through Tuesday morning as the ice and water continue to move downstream. Significant rises in water levels remain possible. Those living in areas prone to flooding should be prepared to take action should flooding develop. Stay tuned to further developments by listening to your local radio, television, or NOAA Weather Radio for further information. && $$ AKZ825-210500- /O.CON.PAFG.FA.A.0004.000000T0000Z-240524T2000Z/ /00000.0.IJ.000000T0000Z.000000T0000Z.000000T0000Z.OO/ Yukon Delta Coast- Including the cities of Emmonak, Alakanuk, Nunam Iqua, Kotlik, Mountain Village, Hooper Bay, Scammon Bay, and Chevak 1259 PM AKDT Mon May 20 2024 ...FLOOD WATCH FOR AN ICE JAM REMAINS IN EFFECT THROUGH FRIDAY MORNING... * WHAT...Flooding caused by an ice jam is possible. * WHERE...The Yukon River from Mountain Village to the Yukon Delta Coast. * WHEN...Through Friday morning. * IMPACTS...Ice jams may result in flooding from Mountain Village to the Yukon Delta Coast. Low lying areas near Mountain Village could flood today through Tuesday. Low Lying areas downstream near Emmonak, Alakanuk, Nunam Iqua and Kotlik have potential to flood late Tuesday night through Friday. If an ice jam forms, water could rise rapidly. * ADDITIONAL DETAILS... - The Yukon River broke up to past Mountain Village on Sunday May 19. The breakup front will likely reach Emmonak and Alakanuk between Tuesday night and Friday, based on historic trends. There is potential for flooding in Emmonak, Alakanuk, Nunam Iqua and Kotlik as breakup progresses. Though this year has mostly been a thermal breakup for the Yukon River, an ice jam did form and release May 19 downstream of Pilot Station which led to flooding. This run of ice could lead to high water downstream. In addition, satellite imagery depicts minimal degradation of shorefast ice along the Yukon Delta Coast. This may exacerbate the situation as shorefast ice could impede the breakup push and lead to backwater in communities closest to the coast. - Http://www.weather.gov/aprfc - Please stay tuned to NOAA weather radio or your favorite local weather news source for updates on this situation. - If you live near or along the Yukon River on the Yukon Delta move valuables to higher ground, stay alert and be prepared to take action.
