More atmospheric river storms are expected to hit California this week, one week after a deadly bomb cyclone brought heavy rain and flooding to California.
🌧 An atmospheric river arriving Sunday night is causing significant impact to travel and infrastructure due to heavy rain, heavy mountain snow and damaging wind gusts through Tuesday.
River flooding, mudslides, power outages, road closures, tree damage and snow load are expected impacts.
Flash Flood Warnings have already been issued in California, including in Santa Cruz County.
Several inches of rain are expected to fall during this storm, likely leading to widespread flooding as rainwater flows into smaller rivers and streams that will eventually move into larger rivers that could flow out of their banks.
⚠️ Typically, California sees about five to seven good atmospheric rivers each year that contribute to the water supply.
What’s different with this one that’s coming, the amount of moisture in the air that’s approaching the West Coast is at least 250-300% of what we normally see in the air as it’s approaching the West Coast.
What else is unique with this storm is the fact that California has been hit with so many of these storms.
And because of the already saturated soils from the previous storms, streams will likely flood quickly.
☔️ Many areas, including the San Francisco Bay Area and Sacramento, will likely see 3-5 inches of rain through at least Wednesday.
To the north in Redding, about 2-3 inches is expected, with some locally higher amounts.
Higher totals are expected further inland and south, including Fresno, where 5-8 inches of rain could fall.
Heavy rain is also expected to move into the Los Angeles area, where 2-3 inches of rain could fall over the next few days with as much as 8 inches in the mountains surrounding the L.A. Basin.
