California is bracing itself for another round of stormy weather, with heavy rain and snowfall threatening the state. The storms, known as “atmospheric rivers,” are expected to bring floods, mudslides, and travel disruptions across the region. Meteorologists have warned that the northern and central parts of California will be hit the hardest, with the worst weather expected over the weekend. Southern California, including the Los Angeles area, will experience its most significant storminess on Monday.
The Sierra Nevada Mountains will see significant snowfall, with measurements in feet rather than inches. The first storm system is set to arrive on Saturday, bringing around 6 inches of snow. However, by Sunday night into Monday morning, snowfall could reach up to 3 feet in higher elevations. Travelers planning to pass through mountainous areas should expect restrictions and closures due to heavy snowfall.
While the Sierra snow brings good news for ski areas, it also benefits water resource managers. The Sierra snowpack has been below average this season, so the additional snowfall will help replenish water supplies.
In southern California, the main concern is heavy rain and the potential for flooding. The storm on Sunday has the potential to bring 2-5 inches of rain, with some mountains and foothills experiencing up to 8 inches. Strong winds, rock slides, mudslides, and power outages are also possible. Creeks and rivers could have strong flows by Monday and Tuesday, so campers and hikers are advised to avoid them. Additionally, big surf is expected from Sunday through Tuesday.
These storms are part of atmospheric rivers, which are ribbons of water vapor that extend thousands of miles from the tropics to the western U.S. These rivers of water vapor provide the fuel for massive rain and snowstorms. On average, up to 50% of the West Coast’s annual precipitation occurs during atmospheric river events.
As California prepares for another round of stormy weather, residents and travelers should take necessary precautions and stay updated on weather forecasts and advisories. The potential for flooding, heavy snowfall, and travel disruptions is significant, so it is essential to stay safe and be prepared for any emergencies that may arise.
