California Prepares for Double Deluge: Understanding the Impact of Atmospheric River Storms

California is preparing for the arrival of two Pineapple Express storms, also known as atmospheric river storms, which are expected to bring heavy rain, high winds, and mountain snow across the state. The first storm, arriving on Wednesday, may cause urban and small stream flooding in Northern California, while the second storm, expected on Sunday, poses a greater risk to Southern California with potentially record-breaking rainfall. The storms could bring significant impacts to all major population centers in the state, with the potential for flooding and strong winds.
