A flash flood warning has been issued for parts of San Diego County as the most powerful storm in a series of three makes its way into San Diego, bringing heavy rain, destructive winds, possible thunderstorms, inches of snow and possible flooding.
The powerful storm started moving in Sunday evening, and will continue through to Monday.
"This is the third and most powerful storm to hit Southern California," NBC 7's Ashley Matthews said. "It will bring periods of heavy rain this afternoon through early evening, with showers continuing through tomorrow morning."

A flood warning has been issued by the NWS for the San Diego River at Fashion Valley from midnight Sunday to midnight Monday.
A winter storm warning is in effect for the San Diego County mountains, including Julian and Pine Valley. The areas will likely see two to six inches of snow at altitudes between 4,000 and 5,000 feet. Peaks above 5,000 feet altitude will likely see six to 12 inches of snow.

Monday's commute will be messy, with heavy rain drenching the roads, said Matthews.
NBC 7 meteorologist Jodi Kodesh said Monday's storm should be the wettest of all, given how saturated the ground will be from the two prior storms.
Conditions are expected to be much drier by Tuesday and Wednesday.
