AccuWeather Forecast: Level 4 storm, Atmospheric River arrives tomorrow

Before midnight Saturday, expect light scattered showers around the Bay Area. After midnight, our atmospheric river will begin to move into the Bay Area.

On Sunday, this will be a Level 4 major storm on our Storm Impact Scale.

Throughout the first half of Sunday, we expect the heaviest rain to remain in the North Bay. Into the afternoon and evening Sunday, the heavy rain will spread across the rest of the Bay Area.

Along with the rain, we will find strong winds in excess of 30 mph.

Rainfall estimates in the North Bay will range from 4"-7".

For San Francisco, the East Bay and the Peninsula, rainfall will range from 2"-4".

For the South Bay, rainfall will range from 1"-2.5".

Flooding is a high concern especially on our roads and on top of our 2020 burn scars (LNU Lightning in the North Bay and CZU Lightning in the Santa Cruz Mountains).

Power outages are likely as well with our strong winds.

A Wind Advisory will be in effect for the entire Bay Area Sunday for those gusty winds 30-45 mph.

A Flash Flood Watch will be in effect around our burn scars on Sunday for the possibility of Debris Flows. This will be one of the strongest storms we have seen in years, so it is a good idea to charge your electronics and prepare to hunker down Sunday.

A High Surf Warning will begin at 11p.m. Sunday along the entire coast for breakers 20-30 feet.

ABC7 News meteorologist Drew Tuma will have live updates on the storm as it moves into the Bay Area on Sunday starting around 2 p.m. You can watch on abc7news.com or on our ABC7 News Bay Area streaming apps for Roku, Amazon Fire, Apple TV and AndroidTV.
