It’s no secret that California has been experiencing one of the most severe droughts on record. But with a strong Pacific low pressure system along the west coast, moisture will finally be heading our way. This particular storm, known as a “Pineapple Express”, acts as an atmospheric river, characterized by its strong persistent flow transporting moisture from the tropics, the Hawaiian region in particular, to the Pacific coast.
Strong winds as high as 100mph along with heavy rain and snowfall can be expected to dominate California, as a cold front trailing the low sweeps across the state. Winter storm warnings and winter weather advisories are in effect for Central and Northern California, as well as higher elevation regions such as the San Bernardino Mountains, where 4-8 inches of snow can be expected. As much as 1-2 feet of snow is anticipated to dump on the Sierra Nevada Mountains, causing whiteout conditions and power outages throughout the region.
As for the lower elevation portions of the state including southern California, flood and flash flood warnings and advisories are in effect, leading to mudslides throughout the area. As the cold front pushes eastward by Saturday, a weak ridge will move into the region, bringing dry air and mild weather for Sunday and Monday. However, with another trough expected to dig along the coast on Monday, light to moderate showers may once again be headed our way next week. Stay safe
