A set of powerful storms that could rank among the strongest in decades will slam British Columbia, the pacific north-west, and northern California this week, with torrents of rain, inches of snow in high altitudes and damaging winds. The region is bracing for widespread power outages and flash flooding, with extreme rainfall that could linger until the weekend.
After a relatively mild autumn, these rains are part of a familiar pattern caused by atmospheric rivers – strong storm systems that can bring both relief and ruin.
