CBJ GUIDE TO FLOOD PREPAREDNESS
Current Conditions:
GLOF Risk Elevated — Monitoring Ongoing
Suicide Basin is nearing levels seen before past outburst floods. If it released today, flooding on View Drive could reach homes and make roads impassable. No alert is being issued yet, but conditions are being closely monitored.
How to Prepare for a Flood
-
Sign up for emergency alerts – Get texts and calls about flood risk in your area.
-
Know your risk – Check the Mendenhall River inundation maps to see if your home is in a flood-prone area.
-
Buy flood insurance – NFIP policies are affordable in Alaska but can take up to 30 days to activate.
-
Make a go bag – Pack food, water, medications, important documents, and pet supplies.
-
Know where you’ll go – Plan evacuation routes, sheltering and parking (see below), and coordinate with neighbors.
-
Protect your property – Move valuables to higher ground and use sandbags or water barriers if needed.
What To Do During a Flood
What is a GLOF?
This video features a lecture by two of our core partners—Dr. Eran Hood from the University of Alaska Southeast and Aaron Jacobs from the National Weather Service. Together, they explain the science behind Glacial Lake Outburst Floods (GLOFs), including how they form, what triggers them, and why Suicide Basin is being closely monitored. The presentation provides valuable local context and helps to explain the risks and response planning underway in Juneau.
