Record floodwaters threaten Juneau, Alaska, due to glacial lake outburst flooding from the Mendenhall Glacier. Residents in the flood zone have evacuated following urgent warnings. Water has breached the ice dam, with peak flooding expected Wednesday morning. This year's flood is predicted to surpass previous record levels, potentially reaching 16.8 feet. Temporary barriers have been installed, but a permanent solution remains under study, causing frustration among residents.
