A powerful winter storm system that dumped rain and snow on San Diego County overnight moved out of the region Wednesday, but it left behind record-breaking cold temperatures across the county.

The National Weather Service in San Diego said multiple regions in Southern California, including Vista, El Cajon, Palomar Mountain and Lake Cuyamaca experienced record-low maximum temperatures.

Rainfall records were also set in Ramona and Campo.

The system moved in Tuesday and brought sweeping downpours, powerful wind gusts and mountain snow at low elevations.

  • Mt. Laguna (6,000 feet): 14 inches

"Aside from the rain, we'll also be dealing with cold temperatures that will be heading our way later tonight," NBC 7 Meteorologist Sheena Parveen said. "We have a frost advisory for the coast, a freeze warning for the inland valleys, expect very cold temperatures also for the mountains and the deserts."

The frost advisory and freeze warning were in effect from midnight to 8 a.m. Thursday. During that time, temperatures could fall as low as 34 degrees along the coast and 28 degrees in the valleys overnight.

There will be no more rain in February, according to forecasters, and a slight warm-up is set to begin Thursday.

The wet weather is welcome in San Diego but some are concerned about the potential for heavy downpours, reports NBC 7's Melissa Adan.
