Juneau, Alaska, braces for potential record floods as melting glacier causes water buildup.

Juneau, Alaska, is facing potential record floods from rainwater and snowmelt flowing from a basin dammed by the Mendenhall Glacier. Flooding is expected to peak on Wednesday, with some residents already evacuating. Temporary levees have been installed to protect over 460 properties, while officials warn of continued flooding risks for the next 25 to 60 years as the glacier acts as a dam. The situation highlights the impact of climate change on local infrastructure and safety.
