Storm Will Plant A Wet One On San Diego This Valentine’s Day

Not to take the romance out of Valentine’s Day, but this year a sturdy umbrella might be a better gift than chocolate or flowers. The National Weather Service says a huge, warm plume of moisture from the sub-tropics will arrive in San Diego County and drench a region that’s already squishy from earlier storms. The system will begin spreading rain late Wednesday. But the core will hit on Thursday — Valentine’s Day — when the moisture rides up the side of local mountains, condenses, and unleashes heavy rain.
