New Glacial Flood Dashboard Helps Juneau Prepare for Extreme Weather

This post examines a new digital tool launched for Juneau, Alaska residents and officials to prepare for sudden glacial lake outburst floods.

It explains what the Juneau Glacial Flood Dashboard offers, why it was developed after damaging floods from the Mendenhall Glacier, and what the platform means for local resilience and global risk management as climate-driven glacier melt accelerates.

What the Juneau dashboard provides

The dashboard was introduced in May after scientists, agencies, Tribal leaders, and nonprofits collaborated to build a locally focused warning and planning resource.

It aggregates multiple information streams so residents can see near real-time conditions around glacial lakes that threaten downstream communities.

Key features and capabilities

The platform bundles operational data and situational awareness tools to make fast decisions easier for non-specialists and emergency managers alike.

Real-time data feeds from monitoring stations that track lake levels and hydrologic triggers.

Aerial imagery to observe lake extent, ice dams, and recent morphological changes at a glance.

Interactive flood maps that show likely inundation zones for different outburst scenarios, helping homeowners check conditions near their properties.

Community access so Tribal governments, agencies, and residents can plan evacuation routes and prioritize infrastructure protection.

Why the tool is urgently needed

Juneau’s dashboard responded to a tangible threat made clear by the Mendenhall Glacier floods in 2024, which damaged hundreds of homes and disrupted lives.

Scientists and local leaders view the dashboard as a practical adaptation tool that complements operational forecasting.

Recent events that drove rapid interest

After the 2024 outburst from the glacial lake below the Mendenhall, state and local attention intensified.

In August, Alaska Governor Mike Dunleavy declared a state disaster preemptively ahead of another potential outburst, signaling the seriousness of the risk.

Public interest spiked dramatically — visits to the dashboard jumped from 12,999 to nearly 45,000 within two days after the declaration — underscoring how much residents value accessible situational data.

Experts such as environmental scientist Eran Hood emphasize that these events are not isolated: growing glacier melt driven by climate change increases both the size and frequency of glacial lake outbursts.

The dashboard is designed for planning and preparedness and does not replace National Weather Service operational alerts; it complements the ongoing monitoring of Suicide Basin and other high-risk lakes.

Broader implications and recommended actions

The local experience in Juneau is a case study with global relevance.

Roughly 15 million people worldwide live downstream of glacial lakes that could fail, meaning better data systems, resilient infrastructure, and proactive planning are essential.

Priority steps for communities and policymakers

Invest in continuous monitoring networks and public-facing dashboards that translate technical data into actionable guidance.

Strengthen evacuation routes, flood defenses, and land-use regulations in identified inundation zones.

Engage Tribal governments and local stakeholders in co-developing warning systems and response plans.

Maintain clear coordination between planning tools (like the Juneau dashboard) and operational forecast centers such as the National Weather Service.

Advocate for rapid reductions in greenhouse gas emissions to limit long-term glacier retreat and the escalation of outburst flood risk.

As an environmental scientist with decades of experience, I view the Juneau Glacial Flood Dashboard as an important step. It brings data to the people who need it and helps bridge science and community action.
