Alaska Capital Juneau Urged to Evacuate as Glacial Outburst Flood Looms

Juneau is facing a high risk of catastrophic flooding due to a glacial lake outburst flood (GLOF) from Suicide Basin.

A disaster declaration has been issued to allow for the rapid deployment of state resources and personnel.

Emergency flood barriers have been installed, but evacuations are still recommended as a precaution.

Climate change is accelerating the melting of glaciers, increasing the frequency and severity of GLOFs.

The Mendenhall River has already risen to moderate flood stage, and is expected to crest on August 13th.

Glacial Melting: Climate change is causing the Mendenhall Glacier to melt at an accelerated rate, increasing the volume of water in Suicide Basin.

Ice Dam Collapse: The basin is contained by an ice dam that is prone to collapse due to the pressure of the water and rising temperatures.

Increased Rainfall: Altered rainfall patterns exacerbate the danger, contributing to higher water levels in the basin.

Evacuation Orders: Residents in the Mendenhall Valley are urged to evacuate the potential flood inundation area.

Emergency Barriers: Emergency flood barriers have been installed along the riverbanks to mitigate the impact of the flooding.

Disaster Declaration: The disaster declaration enables state and local authorities to coordinate resources and support protective actions.

Stay Informed: Monitor emergency alerts and local news for updates on the flood situation.

Evacuate if Advised: Follow evacuation orders and move to designated safe zones.

Protect Your Property: Secure or move valuables to higher ground.

Prepare an Emergency Kit: Include essential supplies such as food, water, medication, and a communication device.
