Alaska's capital suffered massive flooding and record-high water levels after an ice dam burst at a nearby glacier, releasing a powerful surge of rainwater and snowmelt.

The Mendenhall River overflowed earlier in the day, sending water into streets and some residential yards of Juneau on Wednesday.

Some residents were able to return to their home while other areas remained 'closed until further notice.'

'Residents are urged to use extreme caution near damaged structures, stay off riverbanks, and avoid driving through standing water,' a statement from the Juneau city website reads.

'Officials warn that driving through flooded areas can create damaging waves that further impact nearby buildings.'
