A series of systems fed by a continued influx of very moist air was pushed into the central California interior through an atmospheric river set-up for several days. This created high snow levels between 9,000-10,000 feet and heavy rainfall for a majority of the San Joaquin Valley County Warning Area which in turn created flooding and flash flooding of area rivers, streams, and water supply canals. Also debris flows, rock slides, and road ponding/flooding was reported.
