Hydrologic Outlook issued May 4 at 7:12PM AKDT by NWS Fairbanks AK

ESFAFG An ice jam above the mouth of the Fortymile River remains in place and is likely to continue eroding from the downstream side as water levels at Dawson are gradually increasing. The ice jam below Calico Bluff cleared overnight. Eagle and other locations along the Yukon that currently have open water can expect ice runs and rising water levels when this upstream jam releases. No flooding is expected at Eagle. This hydrologic outlook will expire at noon on May 5 and not be continued unless there is a change in the condition of the Canadian ice jam.

Hydrologic Outlook issued May 4 at 10:52PM SST by NWS Pago Pago AS

ESFPPG A prolonged period of widespread showers is forecast to impact the Samoa region beginning Tuesday and continuing through Thursday, with rainfall intensity and coverage expected to increase significantly by Friday and into Saturday. An active trough causing this extended duration of rainfall raises the potential for localized and widespread flooding, particularly in low-lying and poor drainage areas. Peak impacts are anticipated Friday through Saturday, when the trough is most active. Rainfall totals over the event period may exceed thresholds for flash flooding, especially in areas that have already experienced saturated soil conditions in previous weeks. In addition, landslides will

Hydrologic Outlook issued May 3 at 10:43PM AKDT by NWS Anchorage AK

ESFAFC As of approximately 19:30 AKDT Saturday, McGrath ice started running. Water levels have risen but remain below the bank. Ice is very weak and disintegrating as it moves. McGrath has no flood concerns at this time. As of approximately 20:30 AKDT Saturday, Stony River has ice running past. Water levels have risen 3-4 ft and are expected to continue to rise. Residents are not expecting the water level to reach airstrip level. This ice run is more dense, with more water volume, a lot of wood, and running faster than Thursday night. This ice run is most likely ice

Hydrologic Outlook issued May 3 at 12:18PM AKDT by NWS Fairbanks AK

ESFAFG An ice jam above the mouth of the Fortymile River has remained in place since Thursday. With the cooler temperatures snowmelt contribution to the Yukon has not increased water levels at Dawson so this jam has been stable and will likely erode from the downstream side. In this scenario, Eagle and other locations along the Yukon that currently have open water can expect eventual ice runs accompanied by a significant rise in water levels as this jam releases and potentially adds to the current jam downstream of Calico Bluff.

Hydrologic Outlook issued May 1 at 10:03PM AKDT by NWS Anchorage AK

ESFAFC As of 19:15 AKDT Thursday, ice began running past Stony River and water levels rose approximately 2 ft. As of 21:00 AKDT the ice continues to run and the water levels are steady. The River Watch team on Wednesday saw no intact ice until 8 miles upstream of the Tatlawitsuk River. River Watch also confirmed on Wednesday that the Tatlawitsuk, Swift, and Stony rivers were all free of ice. On Thursday evening, local residents in Stony River assume this run is intact ice that was released between Devils Elbow and upstream of the Tatlawitsuk River. At this time, the

Hydrologic Outlook issued April 30 at 7:49PM AKDT by NWS Anchorage AK

ESFAFC As of 16:30 AKDT Wednesday, an approximate 30 mile run of ice was moving downstream between Crooked Creek and Napaimute. The ice run is medium-to-large disintegrating sheets intermixed with large chunks, and moving at ~2 mph. Below Napaimute is open water until near Chuathbaluk where intact ice at varying stages of strength and decay extends all the way to Bethel. Residence in Aniak and Crow Village should expect to see water levels rise overnight as the upriver ice run meets the stronger intact ice sheets downstream and water and ice push through Birch Crossing and overtop the still ice-choked
