Forecasters also warned of heavy snow and strong winds developing in the northern Sierra Nevada and southern Cascade Range, starting out at higher elevations Tuesday and lowering slightly on Wednesday.

Significant travel disruptions were likely across highway passes of the northern Sierra, forecasters said.

Winter weather advisories were to go into effect by late afternoon in the central Sierra above 7,000 feet (2,134 meters).
