An atmospheric river due to hit California in the coming days is not likely to help the situation in the Colorado River Basin, an expert has told Newsweek.

The atmospheric river—a corridor of concentrated, tropical moisture traveling through the atmosphere—is the latest to hit the state in recent months. The river has the potential to cause severe flooding across the state, with experts warning of severe disruption. When atmospheric rivers make landfall, they release vapors as either rain or snow. This can cause severe conditions, and has previously led to mudslides in the state.
