A rush of glacial floodwater swept down Alaska’s Mendenhall River on Wednesday morning, prompting evacuation warnings in parts of Juneau.

City officials say the flood threat has ended and credit barriers with preventing more damage from the Mendenhall Glacier outburst.

Sections of Alaska’s capital city are bracing for the arrival of what could be record floodwaters due to rainwater and snowmelt flowing downstream from a basin dammed by the Mendenhall Glacier.
