A powerful storm could dump a lot of snow in some parts of Riverside and San Bernadino counties. Forecasters say the mountain areas could get up to 18 inches of snow as the storm rolls through tonight and tomorrow. The totals won't be quite so deep at elevations less than eight-thousand feet.
Heavy, wet snow is expected in Crestline, Lake Arrowhead, Big Bear City, Big Bear Lake, Running Springs, Wrightwood and Idyllwild-Pine Cove.
