California is preparing for an upcoming weather system that is set to bring heavy rain and mountain snow to the region. The National Weather Service has issued warnings as an atmospheric river moves into the state, beginning its impact in Northern California and the Central Coast on Wednesday.

According to KTLA 5 News meteorologist Henry DiCarlo, this is a significant storm, with a cold front stretching all the way from Canada to Mexico. The first round of the storm is predicted to bring rain totals of two to three inches in the San Francisco Bay Area and Southern California's coastal areas and inland valleys. In the Central Coast, foothills, and mountains, rainfall amounts could reach four to five inches. Thunderstorms and localized flooding are also expected.

Snow levels are expected to start at around 6,500 feet and drop to as low as 5,500 feet with the first storm. However, a break in the weather is anticipated late Saturday into late Sunday before a second, colder storm moves in between Sunday and Tuesday. The National Weather Service acknowledges a range of outcomes for this storm, but one possibility is that it stalls off the Central Coast, bringing steady rain for 12 to 24 hours and increasing the risk of flooding. Additionally, with cooler temperatures, snow levels could drop as low as 3,000 feet.

Authorities are urging residents to stay updated on the latest weather advisories and to take necessary precautions. With the potential for significant rainfall and snowfall, there is a heightened concern for potential flooding and hazardous conditions on roadways.

As California braces for this powerful storm, it is crucial for residents to remain vigilant and prepared for the varying weather conditions that lie ahead.
