Track the Latest Atmospheric River to Hit California
An atmospheric river continues to bring rain and wind to the Western United States.
Atmospheric rivers are essentially moisture streams in the sky and are often visible from space as narrow bands stretching from the West Coast out across the Pacific.
As these long, thin storm systems move across the ocean and hit land, they often bring extensive amounts of precipitation in the form of rain and snow.
As the moisture moves inland, use the map below to track the amount of precipitation that has already fallen in specific cities, zip codes and other locations.
More rain falling on top of ground saturated by precipitation from recent storms could increase the risk of flooding. The map below shows recent flooding detected along streams and rivers.
As streams rise, they can cover roads and force the closure of highways. With extreme rains, the ground can become so saturated that it gives way in the form of mudslides. Below is a map of recent road closures because of flooding and mudslides.
