SACRAMENTO, Calif. — In northern California and southern Oregon, residents braced for the late Tuesday afternoon arrival of a “bomb cyclone” weather phenomenon that could create waves of up to 35 feet, wind gusts of up to 75 mph and heavy snow in mountainous areas.

The second storm developing in the Pacific Ocean was expected to slam the West Coast of the U.S. on Tuesday evening, bringing snow to the mountains of California and Nevada and wind and rain along the coasts of California and Oregon.

Sacramento is the second most flood-prone city in the United States, after New Orleans.

According to Sacramento Utilities Spokesman Lon Peterson the city of Sacramento acts “like a bowl.” And when it comes to wet weather, like what has arrived with this Thanksgiving storm, Sacramento relies on a series of 150 pumping stations across the city, with more than 350 pumps!

And those pumps have power! Some can move up to 100 million gallons of water a day. There are several pumps of that magnitude at the city’s Sump 2 station in Land Park alone.

The Sump 2 station sits on Riverside Boulevard between 10th and 11th streets. You may have even driven by many times without even realizing what it is. ABC10 got a backstage tour of the facility to learn just how much work is done to clean and direct the water.

In Stockton, San Joaquin County Public Works crews were busy clearing leaves from gutters in the Country Club area of Stockton so drains were free for the storm runoff.
