Atmospheric River to Bring Heavy Rain, Snow to California

Explosive Cyclogenesis to Intensify Storm

A powerful atmospheric river is expected to drench California with heavy rain and snow beginning Wednesday night and continuing through the weekend. The storm, fueled by an "explosive cyclogenesis" event, is expected to bring up to 10 inches of rain and as much as 5 feet of snow to the Sierra Nevada mountains.

What is an atmospheric river?

An atmospheric river is a narrow corridor or filament of concentrated moisture in the atmosphere that transports water vapor away from the tropics. The vapor condenses into rain or snow when it encounters colder air.

Atmospheric rivers are often associated with extreme weather events, such as flooding, landslides, and mudslides. They can also cause significant damage to infrastructure and property.

Explosive cyclogenesis

Explosive cyclogenesis is a term used to describe a rapid deepening of a low-pressure storm system. These storms can develop very quickly, and they can bring strong winds, heavy rain, and snow.

The storm that is expected to hit California is expected to undergo explosive cyclogenesis, which will intensify the storm and increase the risk of severe weather.

Impacts of the storm

The storm is expected to bring heavy rain and snow to California, with some areas receiving up to 10 inches of rain and 5 feet of snow. The storm is also expected to bring strong winds, which could cause power outages and damage to property.

The storm is expected to impact much of California, including the San Francisco Bay Area, the Central Valley, and the Sierra Nevada mountains. Travel could be difficult or impossible in some areas, and residents are advised to be prepared for power outages and other disruptions.

Stay informed

Residents in California should stay informed about the storm and its potential impacts. The National Weather Service has issued a series of watches and warnings for the storm, and residents should monitor the latest forecasts.

Residents should also be prepared to take action if necessary. This may include evacuating to higher ground, securing loose objects, and stocking up on food and water.
