California braces for potential Category 5 atmospheric river, forecasters warn Bay Area will be hit the most

SAN FRANCISCO, CALIFORNIA: A dangerous atmospheric river packing heavy rain and strong winds is forecast to soak Northern California beginning Wednesday, with the potential to hammer the Bay Area in particular through Friday, according to meteorologists.

The National Weather Service warns the moisture-rich storm system could bring rainfall exceeding 6 inches across parts of the North Bay over the next few days, along with wind gusts topping 70 mph in coastal areas.

Forecasters caution Bay Area residents to brace for possible flooding, downed trees, power outages and travel disruptions into the weekend, as per Forbes.

Impact will be felt across the North Bay

Per forecast models, the brunt of the impacts from the incoming atmospheric river will be felt across the North Bay. Total rainfall amounts of 3 to 4 inches are expected in cities like San Francisco and along the Central Coast from Wednesday, January 31, into Friday, February 2.

However, parts of the North Bay could register up to 6 inches of rain over the same period, with the Russian River and San Lorenzo River potentially hitting flood stage. Soils are already heavily saturated, heightening runoff and raising debris flow dangers.

In addition to prolific rainfall, the approaching storm system will tap into the potent jet stream winds aloft. That's expected to drive wind gusts over 50 mph along the coastline and exposed ridges.

The National Weather Service warns mariners that the powerful winds could build ocean swells beyond 14 feet in height. Vessels are advised to remain in port given the forecast of intense winds and high seas.

The gusty conditions will also threaten to down trees and power lines across the Bay Area. Residents are encouraged to secure loose outdoor furniture and debris that could pose hazards.

What is an atmospheric river?

Atmospheric rivers are long, concentrated plumes of water vapor that transport immense moisture from the tropics to the West Coast of North America. Just a handful of strong atmospheric river events provide 30-50 percent of California's yearly precipitation.

When aimed directly at the state and flush with moisture, they can dump prolific rainfall and snowfall over short time frames, mitigating drought and fire risk but also occasionally spurring floods, landslides, coastal erosion, and water damage.

Computer forecast models indicate the incoming atmospheric river may qualify as a Category 5 event - the highest rating on the intensity scale. That signals the likelihood of not only heavy rain, but also strong, damaging winds.

Internet reacts to news of impending atmospheric river

In response to the news, the online community shared a range of reactions. One Facebook user expressed concern, advising, "Stay safe and be prepared for the upcoming atmospheric river, everyone!"

Meanwhile, another user voiced worries about potential cascading disasters, stating, "Just hope it isn't followed by a windstorm. Our town alone lost hundreds of trees this month."

Taking a humorous angle, a third user pondered the potential silver lining, asking, "Does this mean we will not have to hear Californians whining about water after they use a million gallons to irrigate an acre of almonds?"

Another individual reminisced about the past, saying, "They used to call this weather pattern 'The pineapple express.' I guess they think the new name sounds more extreme."

Amidst the mix of concern and humor, a fifth user offered a concise, sardonic remark, stating, "Cry Me...an atmospheric river." Another boldly declared, "And AZ is next. Bring it on."
