first storm of fall brought downpours at times Wednesday. A driver was stranded on a backroad in the Tijuana River Valley Thursday morning. That driver had to be rescued by lifeguards after his pickup got submerged in floodwater. Light to moderate rain showers were expected to continue around the county until Friday, forecasters said. Coastal areas were expected to get between one-tenth and a quarter-inch of rain, while up to three-tenths of an inch were expected in the inland valleys and the mountains.
