SAN DIEGO - Rain due Saturday afternoon could cause dangerous driving conditions on San Diego County roads, with some snow likely in the upper reaches of the mountains.
"There will be enough rain to cause traffic problems with slippery roads making it easy to run into trouble," National Weather Service forecaster Roger Pierce said. "So far, it does not look like there will be that much snow in the mountains, but there will be snow on the roads."
Pierce said 1 to 3 inches of snow is expected in the mountains above 4,000 or 4,500 feet. Not enough snow was expected to require chains.
Pierce said the storm was likely to hit between 2 and 6 p.m.
The drizzly rain will move through the county fairly quickly, lingering overnight before departing Sunday leaving mostly fair skies.
"Tomorrow should be a real nice day after the storm leaves," Pierce said.
Temperatures were cool for this time of year, with 55 degrees Saturday morning at Lindbergh Field, Pierce said.
