A glacier outburst is underway in Alaska. It could send a wave of water downstream toward Juneau
Officials warn Juneau residents to evacuate as a glacial outburst flood from Mendenhall Glacier may surpass last year's 16-foot record, releasing up to 15 billion gallons of water.
- Amid rising basin levels, water started flowing from Suicide Basin toward Juneau on Tuesday morning, with flooding expected late Tuesday through Wednesday.
- A smaller glacier’s retreat created the basin that now fills with rainwater and snowmelt each spring and summer, and federal scientists say climate change is melting the glacier faster, altering rainfall patterns, and intensifying floods.
- Projections show this year’s crest surpassing the 14-foot flood stage, as the river surged to 9.85 feet by Tuesday noon.
- In anticipation of flooding, officials deployed a temporary levee along roughly 2.5 miles of riverbank, and Gov. Mike Dunleavy issued a disaster declaration.
- Long-Term studies indicate the glacier will act as an ice dam for decades, with outburst floods potentially persisting 25 to 60 years, say the university and science center researchers.
