When

Impacts
The Kuskokwim River is currently at bankfull. Soils remain moist and excessive runoff may result in localized flooding of rivers, creeks, streams, other low-lying areas and flood-prone locations.
Additional Details
- Heavy rain is forecasted to begin Monday afternoon. Rain should continue through Wednesday morning with storm total rainfall expected to be around 1 to 2 inches. Minor pooling/ponding of water in low-lying and flood prone areas is possible with the already saturated ground conditions beginning on Tuesday. Small stream and creek flooding is possible as we expect very high water levels throughout the week in response to the heavy rain.
- The Kuskokwim River dropped below bankfull Monday morning. River levels are expected to rise again in response to the heavy rain beginning Monday afternoon and remain high through the rest of the week.
- We will continue to monitor the situation closely and update as necessary.

Tips to Stay Safe
A Flood Watch means the area may experience a dangerous flooding event, and being prepared may save lives and property.
- Be aware of low-lying areas along your travel routes that are most likely to flood.
- Check your home’s emergency supplies, and make sure all members of the household know your emergency plan.
- Stay tuned for local weather updates on the situation as it develops.
If a Flood Warning is issued, it means that dangerous flooding is expected or already happening.
- Never walk, swim, or drive through flood waters or flooded roads.
- Stay away from areas where water levels can rise rapidly, like storm drains, culverts, creeks and streams.
If your home is likely to flood, or if authorities tell you to evacuate, do so immediately and move to higher ground.
