A winter storm is expected to arrive Sunday morning along the coast, bringing light to moderate rain throughout the region into Tuesday, weather forecasters said.

Most of the rain across Southern California will fall Sunday afternoon and evening, according to the forecast from the National Weather Service office in San Diego.

“An approaching storm system moving in from the north today will bring showers and cool conditions to Southern California through Monday night,” the weather service said. “The storm could bring significant snowfall to the San Bernardino County mountains, especially in the Big Bear area.”

Total rainfall amounts for most areas are expected to be from a quarter of an inch to a half-inch, the forecast said. Snow is expected in mountain areas, with snow levels falling to 3,000 to 4,000 feet Sunday night. Mountain areas above 5,000 feet could see as much as three to six inches of snow.

Afternoon highs on Sunday are forecast to be 58 along the coast, 59 in the western valleys, 53 to 58 near the foothills, 47 to 53 in the mountains and 65 to 70 in the deserts.

There is a slight chance of thunderstorms off the coast Monday, forecasters said, bringing the possibility of lightning.

Scattered showers should gradually taper off Tuesday morning as the storm system accelerates east into southern Arizona, the weather service said.
