Atmospheric River Forecast Shifts: Northern California Now Targeted
Updated Predictions Indicate Heavy Rain, Snow for the Region
New Storms Expected to Impact Northern California
Atmospheric river conditions are quickly evolving, with the latest forecast models indicating a significant shift in the storm track. Northern California is now expected to bear the brunt of the upcoming atmospheric river storms, bringing heavy rainfall and mountain snow to the region.
Previously, forecasters had anticipated that the storms would primarily affect Central and Southern California. However, a change in the steering winds has redirected the storm track northward, putting Northern California in the direct path of these powerful atmospheric rivers.
What is an Atmospheric River?
An atmospheric river is a long, narrow corridor or filament in the atmosphere that transports moisture across vast distances. These rivers of moisture originate over tropical oceans and can extend thousands of miles, carrying an enormous amount of water vapor.
When an atmospheric river makes landfall, it can unleash torrential rainfall, triggering floods and mudslides. Atmospheric rivers are also responsible for delivering much-needed precipitation to drought-stricken regions.
Impacts on Northern California
The atmospheric river storms are expected to bring heavy rain to Northern California, with rainfall totals potentially exceeding 10 inches in some areas. The rain is likely to cause flooding, especially in low-lying areas and along rivers and streams.
In addition to the rain, the storms are also expected to bring significant mountain snow to the Sierra Nevada. Snowfall totals could reach several feet, creating hazardous driving conditions and increasing the risk of avalanches.
Timing and Duration
The first atmospheric river storm is expected to impact Northern California on Sunday, January 29th, and will likely continue through Tuesday, January 31st. A second storm is forecast to arrive on Wednesday, February 1st, and could bring even heavier rainfall.
Preparation and Safety
Residents in Northern California should prepare for the upcoming storms by taking the following steps:
- Secure loose outdoor items, such as patio furniture and garbage cans.
- Clear gutters and downspouts to prevent flooding.
- Have an emergency plan in place, including an evacuation route and a list of emergency contacts.
- Stay informed about the latest weather forecasts and be prepared to take action if necessary.
