San Diego may add another inch or so of precipitation to our strong winter rainfall totals after another storm moves through the region early this week. A storm system churning off the coast of California was expected to bring some light rain to San Diego County as early as Monday, according to NBC 7 Meteorologist Brooke Martell. Some light showers touched down early Monday but the brunt of the storm was expected to impact the county Tuesday when showers become heavier and more widespread.
