Palomar Mountain was expected to receive 12 to 18 inches of snow. Lower elevation mountain communities, such as Julian, were expecting eight to 12 inches.
The heaviest snow was predicted to fall Wednesday evening into Thursday morning.
By 5 p.m., officials said chains were required on Sunrise Highway from Interstate 8 to State Route 79.
A winter storm warning for heavy snow goes into effect at 1 p.m. Wednesday and will last through 1 a.m. Friday. Residents were warned to stay off the roads in mountain areas unless they were prepared with chains and other safety precautions.

Snow showers were expected to linger near the mountains through Friday.
Wednesday night around the county was expected to be partly cloudy, with showers starting in the afternoon and increasing in the evening.
