catastrophic flash and urban flooding impacts across Los Angeles.

Nevada and near Mt. Shasta through tonight. 2-3"/hour snowfall

rates combined with wind gusts will lead to whiteout conditions

and near impossible travel above 5000 feet.

Center at 700 PM PST. Please refer to your local National Weather

Service office for additional information on this event.
