A potent storm system is sweeping through California, with meteorologists warning residents to prepare for possible flooding, hail, strong winds, and even brief tornadoes. The storm, which started gaining strength early on Monday, is predicted to bring significant rainfall to many areas, with up to 5 inches expected in some regions. Isolated rain totals of 10 inches are possible in certain mountain ranges as the storm progresses towards greater Los Angeles.

Residents in various cities, including Sacramento, Chico, Yuba City, Stockton, and Modesto, are advised to closely monitor weather updates and exercise caution. Flash flooding and power outages are among the potential issues that the storm may cause. The National Weather Service has issued flood watches and warnings for coastal and mountain areas across the state.

In addition to heavy rainfall, the storm is expected to bring strong gusts of over 30mph to cities like Oakland and San Jose. Thunderstorms in the vicinity of the state capital could result in the formation of brief tornadoes, along with heavy rain, small hail, lightning, and gusty winds.

As a precaution, the California governor's office of emergency services has activated its operations center and deployed personnel and equipment to high-risk areas. Motorists are urged to avoid mountain routes, and the weather service in Reno, Nevada, has cautioned travelers to consider rescheduling trips to the Sierra Nevada region.

With several feet of snow possible at higher elevations, the storm poses challenges not only in terms of flooding but also in terms of potential avalanche risks in the Lake Tahoe area and the eastern Sierra region. The storm is anticipated to move through the state at a faster pace compared to a recent atmospheric river event that caused devastation in southern California earlier this month.

Emergency responders rescued a man in El Dorado Hills on Monday morning after he became trapped in a tree due to rising floodwaters. The storm is expected to continue impacting the state over the next few days, requiring vigilance from residents and authorities alike.
