Locals are mopping up after yesterday's storm but there are still plenty of hazards.
PEOPLE in Mandurah and surrounding areas are waking up this morning to survey the damage caused by yesterday's ferocious storm.
Hundreds of power lines are still down, trees are blocking roads and thousands are without power after the 'once in a decade' storm tore through the south west.
Emergency crews have worked through the night making temporary repairs to houses and Western Power teams are trying to restore power wherever possible.
Residents are warned it could take up to a week for power to be restored in some areas.
