DISCUSSION: As heavy rainfall continued to persist throughout the day across many parts of California, many areas experienced severe flooding and even flash flooding in many cases. As reflected by the footage above which was captured earlier today (courtesy of Ivan Natividad and TheUnion) over in Nevada City, California, some floodwaters became incredibly dangerous as they engulfed entire communities in raging "white water" rivers. This was caused by persistent torrential downpours over the same areas for a relatively long period of time. Furthermore, this was then worsened by the natural rainfall water run-off which was induced by the positioning of valleys and ridges in and around both Nevada City, California and many other cities across the state of California as well for that matter. Unfortunately, these sort of floodwaters are expected to persist as torrential downpours continue for at least the 24 to 48 hours in many places across central-to-northern California.
