Flood — Susitna Valley, Alaska

2023-08-27 to 2023-08-28 · near Talkeetna, Susitna Valley, Alaska

Event narrative

One to three inches of heavy rainfall flooded low lying areas of the Susitna Valley, including the main road that crossed Kroto and Moose Creeks. This road closure limited resident access to their homes.

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.
