Flood — Susitna Valley, Alaska

2023-08-26 to 2023-08-30 · near Skwentna, Susitna Valley, Alaska

Event narrative

Flood waters encroached on cabins along the Yentna and Skwentna Rivers. 2-4 inches of rain fell within the basin causing river levels to swell, and inundating land areas alongside cabins on the river's edge of the Yentna and Skwentna Rivers.

Wider weather episode

Widespread precipitation fell across the Talkeetna, Susitna, Yentna and Skwenta Basins in late August as a deep, upper-level low anchored itself over the Bering Sea, sending waves of precipitation through the area. The persistent moist pattern followed a prolonged period of wet conditions over the previous months, leading to high flows and flooding across the Susitna Basin and associated rivers in the basin over the course of the period.
