A powerful winter storm will move into Southern California Thursday night, bringing the potential for heavy rain and high winds through the weekend. The brunt of the storm system won’t arrive until Friday when moderate to heavy rainfall is expected to fall across San Diego County. Coastal areas could see with 1 to 3 inches of rain. “Usually, our winter storms provide the bulk of rain in the mountains,” said NBC 7 Meteorologist Jodi Kodesh. “But, this time, even our coastline is expecting heavy rain & high winds.”
