A storm off the coast of the US north-west and western Canada is pummelling the region - bringing high winds, flooding and snow to over seven million residents living in states along the Pacific Ocean.

The storm has caused widespread power outages for hundreds of thousands of Americans, and its strong winds have downed trees.

At least person - a woman near Seattle - has died.

The “bomb cyclone” - as forecasters call it - has been caused by air pressure quickly dropping off the coast, which has rapidly intensified the weather system.
