A band of light to moderate rain swept across coastal and valley areas of San Diego County early Monday at the same time as snow fell in the mountains, prompting meteorologists to issue a travel warning.
The National Weather Service had issued a winter weather advisory for mountain areas above 4,500 feet until noon, but the advisory was lifted at 9:30 a.m. when the storm moved out earlier than expected.
A winter weather advisory means that periods of snow will make travel difficult. Among the areas included in the advisory were Cuyamaca, Mount Laguna and Ranchita.
"Residents and travelers into the mountains should be prepared for hazardous driving conditions due to slick roads," an NWS advisory said. "If possible, carry chains and take extra food and clothing."
Mountain areas this morning were also subject to sustained southwest winds of 15 to 25 miles per hour and gusts up to 40 mph.
By 6 a.m. -- before the rain departed coastal and valley areas -- the California Highway Patrol recorded 40 crash reports on rain-slick local highways and freeways. The CHP typically said it receives 50 to 75 crash reports during a 24-hour period on a ''good weather'' day.
