An atmospheric river from the north that made its first push into the Bay Area over the weekend got its second wind Monday night, “over-performing” the National Weather Service’s expectations, the agency said. The storm, which is “stronger than expected,” caused minor to moderate flooding in some areas.

More light rain is expected to fall periodically through the Bay Area on Monday, continuing a pattern that began Friday and ended a nearly month-long stretch without the wet stuff. The latest question is when will the region be without it again?
