A pair of powerful atmospheric river events brought heavy precipitation across much of coastal California this week, resulting in record rainfall totals, extensive flooding, numerous landslides, hurricane-force winds, and power outages.

The first event had the greatest impact on northern and central California. It was initiated when a large low-pressure trough located in the northeast Pacific
