The Western United States and Canada are likely to see excessive rain and heavy snowfall from a sequence of back-to-back atmospheric rivers beginning this weekend and continuing into next week.
In the coming weeks, buckets of rain are likely to batter California. The culprit? Atmospheric rivers. The rains are born far away, deep in the tropical Pacific, where water evaporated from the warm ocean surface is absorbed into the atmosphere.
Despite a spate of recent storms, scientists say California needs more winterlike weather to bolster its water supply and avoid another drought.
