Juneau Issues Avalanche Evacuation Advisories as Atmospheric River Drives Flood Threat

Warm rain on a deep December snowpack is accelerating melt, with hazards expected to persist into early next week.

Overview

  • Flood Watches cover much of Southeast Alaska, with alerts in Juneau through Saturday evening and in the southern panhandle through Monday morning, according to the National Weather Service.
  • The City and Borough of Juneau advised residents in mapped slide paths to evacuate, closed Thane Road, and opened emergency sheltering at Centennial Hall with emergency crews staged.
  • Natural avalanches were reported on Mount Juneau and along Thane Road paths, prompting closure of city facilities and a Friday school shutdown as officials warned of increasing risk with more rain and wind.
  • Rain-on-snow is producing urban flooding and ponding as clogged drains struggle to keep up, with reports of water in homes and on roads in Douglas and 4–5 feet of pooled water at a Juneau intersection.
  • Forecasts call for roughly 1–4 inches of rainfall across the panhandle with higher totals farther south, and previously issued local, tribal, and verbal state disaster declarations are supporting the ongoing response.
