Atmospheric Rivers Linked to Landslide Risks in Alaska
US · Published Oct 29, 2026
• Recent research highlights the role of atmospheric rivers (ARs) in triggering extreme precipitation events that can lead to landslides in Southeast Alaska.
• These ARs are characterized by strong vertically integrated water vapor transport (IVT), which contributes to heavy rainfall and flooding.

Impact & Risks

Atmospheric rivers pose significant risks to communities in Southeast Alaska, particularly during extreme precipitation events. Heavy rainfall associated with ARs can lead to flooding and increase the likelihood of landslides, which may threaten infrastructure, homes, and public safety. Emergency managers and local authorities rely on forecasters to provide timely warnings, but the unpredictability of landslide occurrences adds complexity to disaster preparedness. These events underscore the importance of situational awareness and advanced forecasting tools to mitigate risks and protect vulnerable populations.
